Your videos are just fantastic. I’ve learnt so much from them. I think your delivery style is excellent: concise, clear, easy to understand and enjoyable. Thank you so much for providing them free for us to benefit from them.
I really appreciate Dr.Veer’s videos. I believe his approach is comprehensive and holistic. My one criticism is background music. I really don’t understand why so many utubers use so much overbearing and distracting background music, I wish somehow this annoying and increasing trend would stop.
You are a rarity person with great sensitivity and compassion, this information is so well explain and important for the user how most of the time can’t interpret all this medical graphics, thank you so much.
Wonderful video. Truly. I'm going to ask my Dr for the raw data as he was seemingly only concerned with AHI. Clearly, that is not telling the story. I found your data breakdowns very easy to understand and follow. Great job, great video.
Brilliant. Just had my report back from my specialist in France. I was able to understand my report which was in french. And when I spoke to my guy I was able to show him I understood. So you really saved the day. A thousand thank yous. Waiting to get my CPAP machine fitted and I will DEFINITELY persevere and win through with this as I now understand my scores of moderate IAH 22 and IDO 13.3. Plus all the detailed data....well almost all of the stats.❤
Thank you so much for posting this. My AHI was 67, now it's under 2, thanks to my CPAP. My sleep clinic has been unable to see me and explained this, due to covid. When face to face appointment resume, I'll have some insight, when this is explained to me. So thank you again.
Oh my God, Thank you so much for this video. It's because of videos like this and people like you that internet is the treasure trove of knowledge that it is. You have no idea how much this video has helped me. 🙏 Thank you so much.
This level of information is exactly what needs to get out, because most doctors either keep this information away from us patients, or may not know everything themselves even.
The discussion at 7:20, about AHI relative to sleep position, is so overlooked at yet so critical. It is great evidence for multiple night studies. Having data from a single night is like monitoring someones driving for one day and deciding they never speed because they happened to not drive anywhere that day.
My first sleep study oxygen reading was 77%. Alarming! But I only had 9 events per hour. That was about 3 years ago. I was first given CPAP, then about 18 months later, BIPAP. Last year, I stopped using my machine for months. After that, a new sleep study by a new doctor: 15 events per hour, 95% oxygen. He put me back on CPAP. I honestly don’t notice a difference sleeping with the machine or without it. I am 68 years old and 20 pounds overweight, working on weight reduction. Last year, I lost 30+ pounds. Thank you for these great videos. Best wishes from Michigan, USA. Side note: I was sleeping in great pain for a couple of years due to osteoarthritis in both hips. I never got a good night’s sleep. I had my hips replaced last year and that has made a tremendous amount of difference in the quality of my sleep.
I now understand my sleep study better thank you - I was going to give up on the cpap it’s been a frustrating journey however now appreciating how serious my Q2 dropping to 60% during my rem sleep I’m going to persevere in finding a mask I can wear all night
You have no idea how happy this comment made me. Thank you! Incidentally REM OSA is often related to the tongue falling back. Try wearing a woodyknows backpack (see video on positional sleep apnoea), with a chin strap (see the Knightsbridge dual strap video on it), and a Philips dreamwear nasal cushions (it'll normally fit on any CPAP machine). Use all that and see if your O2 still drops after 3 weeks (takes time for you to get comfortable and to notice the benefit). REM OSA also causes a lot of brain fog and that takes time to clear too. With time you should be able to stop using the backpack and the chin strap (6 weeks or so?). If you are still struggling consider a MAD with all of that and then see if you still have drops occurring. If not wait the 3 weeks for you to pay back your sleep debt and start removing things until you are just on the mask. Sorry I can't explain it all to you, but ask your sleep lab and they will explain why it'll work and what order to stop using everything. They will be able to see from the sleep data to guide you. Good luck.
@@VikVeerENTSurgeon you are a gift to all of us - thank you for your detailed response and recommendations- I have not been very happy with my sleep lab the after care has not been great so I saw a different sleep technician who was recommended to me by a friend - she explained my sleep report in detail - also adjusted the pressure level on my cpap machine from 4-6 to 5-9, changed the humidity level and provided me with a different hose that provides warm air and a Resmed nasal cushion mask. I told her I was a mouth breather she explained we often breathe through the mouth because we’re snoring - i trialled the nasal cushion last night without the chin strap I lasted 6 hours and I had 1.4 events per hour, which I think is pretty good as my AHI in the sleep study was 24 I typically sleep on my left side but appreciate I change positions throughout the night- i so wish I could have a consultation with you here in Sydney Australia :)
Thank you so much for this video! It made sense and now I feel prepared to go to my sleep study follow up appointment tomorrow, where I'll learn my own results. I appreciate your time and help!
100%... I no longer use the resmed app or engage a sleep tech. I use sleep HQ to review my sleep data from my Airsense 10. I used an o2 ring to check my oxygen which was normal during sleep. I ended up needing a travel pillow because my jaw falls backwards when I sleep and now with APAP and the pillow my AHI is on average less than 1 and that's on my back. The reason I mention this is because my sleep study report had a lot of glaring omissions like 0 supine sleep data which I really needed in order to properly figure out the right treatment for me so it's definitely worth educating yourself and take ownership of your own therapy.
I was told my AHI was 85.2 and I had no idea what that meant. The first doctor I had when I asked for the info said I would not understand it anyway so he refused. My 2nd doctor at least is more into communication and working as a team with the patient. I am in Canada. Watching this video makes me want to learn how to read my chart as I really am as bad as the lady at the sleep clinic said I was wow!!!
Holy cow, I’ve learned a lot as a health practitioner about sleep studies and have never seen someone desaturate to 46%. You’re right, you are lucky to be alive.
Me too around 40% was happening regularly for a long time for me It got so bad for me All my body was like in big trouble It got to where I couldn’t sleep not even 15 minutes I would sit up and dose without even sleeping for minutes at a time That all the rest I would get
Everyone who sleeps on their back during a sleep study will have apnea. The test is designed for supine sleeping, isn't it? And the study can tell how long you are sleeping and in what position? I didn't know anyone is actually allowed to sit up. I was almost strapped to the bed in such a way as to not be able to move from a supine position. My report said to sleep on my back less. I don't sleep on my back nor did I sleep as long as they said. I literally slept about 2 hours if that long. It was 3 or 3:30 am when I finally slept and they woke me up about 4:30 or 5. Never got to see the report, didn't talk to the doctor before or after. Someone even marked out the doctor's remarks about me having minimal snoring. And what gets me is there is always a magic rabbit pulled out of the hat when someone does not have apnea bad enough to use Cpap. Oh, yeah, a number somewhere on that report can be used to justify it. AHI, ODI, etc. "Oh, your oxygen dipped for ten minutes during 7 hours of sleep. You need a CPAP stat." Do y'all have no conscience? Being a sleep doctor must be very lucrative. How many doctors do you compete with? How many hours does someone have to actually sleep for the study to be correctly interpreted? How about that? I was told the amount of time I slept was enough. Two hours of fitful sleeping is enough to diagnose someone? When they are waking up because they don't want to sleep? Because they don't want to sleep in a strange place with electrodes taped to them and lights on? Are y'all serious?
just for the record, we conduct over 95% of our sleep studies at home, and so people are in their own beds. We provide all the care for free on the NHS, and we ask people to sleep in any position they want. If that was your experience, you ought to go somewhere else. My job on the NHS is to help people come off CPAP, not get on it. sounds like you had a terrible time, I don't want you to name and shame the place. just find somewhere different. Good luck, and I hope you get your thing sorted.
@@VikVeerENTSurgeon I live in Arkansas. Not too many in rural areas and they all want you to go to same sleep doctor. I had to insist on another full study because they just wanted to do the titration again. Yes, it seems like a racket around here. I know what my problem is and getting a doctor to at least check it has been a problem. Doctors here dont like to be questioned especially if they dont know whats going on with a patient.
Brain waves don't lie. They know exactly how long you were asleep & awake. Sleep misconception is very common & people often think they slept a lot less than they actually did. And enough with the sleep field being a racket. People can die from apnea.
During my two sleep apnea studies I couldn't lie in bed as I normally would. I slept almost entirely on my back because I was tied down with massive numbers of data cables. I felt like Gulliver on the beach. Normally I sleep more on my sides because I find it easier to breath that way. The AHI of 80+ was certainly skewed because I was tied down onto my back.
That really sucks. Have you thought about checking out other places? Maybe you could talk to your Dr. about it. The hospital I went to let me sleep in the recliner in the room. I told them that’s how I sleep at home because I can’t lie on my back & sleep I feel like I’m suffocating. Found out I gotta have a bi pap with oxygen.
A young man close to me has recently got CPAP machine and has AHI at 105 per hour, which seems alarming when 30 is severe, and none of your examples were anywhere near this high. I'm pretty worried! His mean SPO2 = 92%, CT 90 =14% (don't know what that is?). I will suggest he obtains a full report of the sleep study, which was done at home over just one night a few months back. Thank you for this information and much more on your other videos. Very much appreciated
My AHI was 102, CPAP is working great for me :) Mean SPo2 is his average blood oxygen level. CT90 is the overall amount of time he spent under 90%. My figures were worse than this.
Fantastic and informative video. I hope sleep study administrators have your knowledge, but I'm affraid they may not, and perhaps mis-diagnosing the problem. I've requested my sleep study info so I can review it. thanks again.
Loved the video! Great to be able to appreciate all the different parameters seen in the NOX T3 device and software program. Definitely more thorough than other HSAT devices.
I can't tell you how valuable this video was for me - thank you so much! I've been suffering from feeling like I haven't slept for years. After watching your video, I asked for my sleep study after they only gave me a single number AHI of 13.6. They then sent some summary information but did not include the graphs. I have interpreted the information based on the guidance you gave. Could you please tell me if I'm on the right track. The data they provided was TST=4h 42min, AHI=13.6, 2 obstructive apneas, 3 central apneas, 8 mixed apneas, 8 RERA events, 51 hypopneas, minimum O2 88%, less than 90% for 28min, mean O2 95.9%, 30% TST in supine position AHI=29.1, 70% TST non-supine AHI=7, RDI=15.3. I believe it indicates that I should stop sleeping on my back, and that should substantially help my sleep apnea. The study also indicated mild to moderate snoring but I don't have the graphs to correlate with sleeping position - I will be asking for the graphs. Am I on the right track? A slumber bumper will probably help me correct? What should I make of the 8 RERA and 15.3 RDI? Not sure what they mean. I've also started your exercises. Thanks again for this amazing video!
BTW, the only thing the sleep doctor told me was my AHI was 13.6 and I could probably benefit from CPAP. I tried and could not tolerate it because my nose is always congested. I wish she would have gone through my study as you took us through the samples. Would have saved me a lot of aggravation!!
Really hard for me to give you advice based on this, but my guess is that you have OSA when sleeping on your back, and then UARS (see video on this), when sleeping on your side. I would say that sleeping on your side (slumberbump is a good product - but i'm yet to review it), is a good idea. Also think about a Mandibular Advancement Device (trying to do that video too). Sorry I can't be any less vague. I hope it helps anyway.
Very good explanation 👍 I wonder why the doctor that analyzed the data, did not mention that I have almost zero obstructive apneas (1.2/h) when I am on non-supine positions 🤔
Very informative video. Thanks. I was just diagnosed with sleep apnea. I got the results of my sleep result today. Apparently I'm almost triple severe! My AHI was 85 with an average oxygen level of 85 as well. They just put in an order for my CPAP SO waiting for the call.
Thanks for this video. Perhaps the main shortfall with AHI scores is that they relate only to the frequency of stop breathing events, with no consideration for duration. Paradoxically, persons with extremely long events ( say more than a minute ), may have only modest AHI scores.
Great video! My sleep studies have no RIP Phase or Flow Limitations data :(. My severe sleep apnea seemed 'fixed' after some surgeries because the AHI was around 5. But the RDI was around 15 and oxygen levels dropped to less than 88% for about 32 mins. I still feel very tired and this has a toll on my mental health but some doctors just dismiss it seeing the AHI alone. Would you say that the RDI and oxygen levels I mentioned explain what I feel? If only my sleep study had RIP Phase and Flow limitation data!
It sounds very plausible. Do speak to someone who will look at it properly for you. - have a look at this video which I think might help you. - ruclips.net/video/sa9zNYpTWlM/видео.html
Thank you very much for the technical insight, I hope to employ this analysis on a second sleep study soon. I had a sleep study done several years ago and relate very much to the last case you mentioned - having the symptoms of sleep apnea but being told there's no problem, and suspecting I have UARS at least.
This is fantastic, thanks! Unfortunately, my sleep study was less detailed than the examples you looked at. It didn't break out apneas versus hypopneas, for example, and didn't show what body positions were associated with which apneas/hypopneas. Maybe this is because I did the sleep study at home with WatchPAT?
Oh sorry now I see you said watchpat. Watchpat got approved on a wink and a nod. Do it again with a good lab. I high cpap reviw channel covered how they were approved and why it shouldn't have been
So fascinating. I just looked at my trst results and realized I only had hypopnoeas, especially on my back. Im a week into CPAP and I am starting to feel better despite struggling to get used to the equipment.
Hi Mr Veer, Just a quick question to pick your brain if I may! What would you say that constitutes 'normal' or non sleep apnea metrics on a sleep study? Is it a certain AHI, say 5, in the most vulnerable sleep position for OSA, or stability of oxygenation etc Many thanks if you can assist.
Matt b, 5 and under is considered normal for ahi but watch lanky lefty's videos, he says you shouldn't go by the ahi number. (Mine was 5.9 with a mandibular device they told me it was minimal but I was having spo2 at 82-85% for 2 hrs a night - def not ok).
I have extreme sleep apnea but before i got tested i had recorded my snoring, The recordings show clearly the apneas where I do not breath for a bit then load snoring when I do, but when it gives an overall rating for the snoring it says it is not very loud, and that is because it basically averages the whole night, and if I spend 50% of the night not breathing(yes it was that severe) then that 50 of the night I am not making any noise.
I just purchased a Sleep O2 ring which measures sleeping O2 and heart rate from Sleep HQ which I can upload with my Cpap data. It aligns with the data. It's not cheap - requires premium membership- but I'm fed up trying to get data/analysis from the doctor. Cannot get my Fitbit which measures these to connect to the Fitbit app- very frustrating. Hoping I can plan better management. I think sleep medicine is easy money for many docs. The techs don't even tell you the data can be obtained from your machine when asked.
Hi Dr Vik, I have a deviated septum and severely blocked nose most of the time leading me to mouth breathe as I physically cannot through my nose, can this contribute the sleep apnea?
Sort of... Nasal obstruction makes sleep apnoea harder to treat, but doesn't cause sleep apnoea on its own. Sorry for being vague - it's actually quite complicated.
Thanks very much for posting this doctor. I had a sleep study performed a few months back on the N.H.S, but have still not heard anything because of some sort of backlog. I might try asking them to send me the results in the meantime. Are the results something that would be produced immediately? And so am I just waiting for interpretation? Thanks.
Thank you so much for this video! I was diagnosed with mild REM related OSA and mild positional apnea. Oxygen dropped to 85% at one point, and pulse rose to 120 bpm but in both of those instances the report says “excluded periods” for respiratory periods. So I don’t know what to make of them. Total AHI is 5 and total RDI is 28. It was a home study so I don’t have some of the other useful data. Could this point to UARS if I’m experiencing gasping events regularly on my back and yet numbers seem too low for OSA? Would a mandibular device be a good start? They want me on a cpap but I am unsure.
it is pointing to UARS - but that report sounds like it came from a WatchPat device? Might be worth doing a more complete study like on a NoxT3. I think a Mandibular Advancement Device would be a great idea.
I have mild sleep apnea. Pretty much a zombie with pseudo arthritis when left untreated so the term mild is pretty bullshit to me but that's another story. Anyway, mandibular works well for mild. I just graduated engineering and couldn't have done it without my mandibular. The cpap didn't give me the same energy boost the mandibular did.
Hi Dr. Veer - I'm wondering if you have an opinion about the various Home Sleep Test devices currently available. It seems like there is a trend toward smaller / disposable devices (like WatchPat and NightOwl) which rely more on complex tech / algorithms to "estimate" apnea events and sleep architecture. Do you think the Nox T3 (now T3s) is a better device to collect the kind of data necessary to diagnose UARS, for example?
Hi Dr. Veer, for apnea/hypopnea, do u know why they decided on the number 10 seconds as the magical number? For ex, what if a patient had events that were like 7-9 seconds, wouldn't they still be significant? However, they would not be counted because the event was not over 10 seconds....
you are right, it's a bit rubbish. most of us just look for arousals and dips in oxygen / effort in breathing. we don't count the seconds. that's why you need a good sleep study equipment. otherwise you are likely to get an unrepresentative result.
@@VikVeerENTSurgeon Also, a general question for you if u don't mind. Do sleep doctors account for the fact that patient's don't sleep well or like they normally do at home for in-lab studies? Like the first night effect, i feel sleep inlabs is not as "bad" as it would be for patients at home due to sort of being more alert in a new environment. The reason i am asking is because I know for my in-lab, i feel my sleep was not representative of my sleep at home at all. I had such a hard time falling asleep, possibly due to new environment/setting/wires/ being nervous/anxious or something. And then i also woke up in the middle and again had trouble sleeping. This is never the case for me. I'm usually out cold around 11-12 and up at 7-8 AM. And sleep the whole way thru. I actually feel like i barely slept for my inlab study. I recall being awake/alert for a large part of the study, which became increasingly frustrating mentally as i knew this was very important for me diagnostically. I feel my in lab study resulted in data that was falsely lower than it would have been had i slept like I normally do. I also had less reduced REM sleep (most of my events were in REM sleep), also making me think had I had more REM sleep my AHI would have been higher. I had an AHI of 6.5 but my sleep doc says i'm fine and don't need tx, despite complaints of classical symptoms such as morning headaches, brain fog/cognitive issues, poor unrefreshing sleep. I also saw your video on UARS. I'm just a person trying to get proper good quality sleep. And not have horrible morning headaches. I'm assuming due to my results, they feel i'm on the lower side and don't really need a cpap machine. I feel it doesn't hurt to try, perhaps it would resolve my symptoms. Maybe there are better ways to navigate this, but as a patient and layman, it's hard to know what to do. Any thoughts would be appreciated. thanks again.
If you are worried about a sleep disorder then an in hospital PSG is required. if you are just worried about a breathing disorder (like OSA or UARS etc), then a home study I think is superior. you can do everything at home except have the video on you but we aren't interested in epilepsy or sleep walking etc. I would have a PSG at home.
@@VikVeerENTSurgeon ahh i see. Thank you for response. Also, if you don't mind, what's your thoughts on cpap treatment for mild sleep apnea or UARS. I read varying things, some sources state benefit isn't so great unless one has closer to moderate or severe apnea. For me, the biggest thing is the horrible morning headaches, cognitive issues, and somewhat feeling drowsy. I think its mostly a breathing issue but I feel i'm on the milder side or a case of UARS. Wondering if cpap can still provide benefit.
I have 2 sleep reports with NoxT3s - one before and one after throat surgery.. What are the chances you can view these and comment.. My snoring went down but AHI increased after surgery.... love your videos btw - so good to have someone explain these things!
What abou AHI and RDI values during REM sleep and The same values for overall sleep? Which are the ones important to look for... to classify the sleep Apnea case?
I have tried two at home sleep studies and I couldn’t sleep either time, I tried for a week straight with both and my dr said there almost no data on my sleep and would have to do it again. Not sure what to do but try and get a referral for an ent and hope they have some answers, I am so completely wiped out almost every day!
Thank you very much for the video. Would it be possible for you to do one focused solemnly on Central Sleep Apnea with the analysis of the sleep study? It would be important to also learn about the different types of apneas, beyond the obstructive.
Hi Dr, thanks again for a very helpful vid. So one assumes the NoxT3 software only works with the initial test results and not with the Resmed Airsense 11 software? Im using Oscar to read this software and under Flow rate it often has multiple clear airways.....can I ask what is clear airways? you are a star. Oh just found another one of your Vid and am I talking about UARS?
Hey man if you see this it would mean the world… Do you think it would be possible for someone to be mis diagnosed with Narcolepsy type 2 but instead have UARS? I had a sleep study done that was normal with apnea’s but never truly aligned myself with the symptoms of narcolepsy. God bless
I guess it's possible, but it would be odd for a sleep doctor to get them mixed up. get someone to video you whilst sleeping - if you are breathing really heavily, it might be worth looking into it again.
@@VikVeerENTSurgeon tysm man, during my sleep study they recorded me but my father slept in the same room because I was a minor at the time. He snores pretty loudly so Idk how they would of noticed my noises over his.. Appreciate it so much. Thinking of doing another one now that i’m older to be sure.
I need you as my dr.. i literally feel like im dying or having a stroke most days if I dont have a perfect sleep. Drs havent helped me and sleep dr simply rebooked a sleep study 4 WHOLE months later.. i literally am afraid to drive in case I crash.. dont know what to do but thankfully my brother had a sleep apnea machine to lend me. Just havent been able to sleep with it yet.. I want to get surgeries and a dental device to bring lower jaw forward. I also have a deviated septum which no dr seems to have noticed yet or care about.
Thank you for these insights. Could you share some information on how these polygraphs technically work? Reason of asking is that the sot polygraph records 6h of sleep while im almost certain i slept significantly less. How does the device register i am sleeping and how accurate is this?
Errrr.... I guess. It depends on the equipment and how blocked you are. It isn't meant to pick this up, but it can confuse the readings if you have a blocked nose. vague answer I know, but it's quite complicated. Sorry!
I've heard RDI is a much more useful metric than AHI. RERAs aren't as bad as hypopneas, and hypopneas aren't as bad as apneas, but they're all still bad. I'm getting oxygen desaturations, loads of flow limitations and RERAs, and nobody in Canada will even acknowledge there's a problem because my AHI is low, so I don't know what to do.
Fellow Canuck. Suggest you follow Sleephq channel. He's a sleep tech in Australia who has sleep apnea. He has developed a tool to upload your data - like OSCAR. You can keep one month data for free. He has lots of great videos and is very responsive to questions. I just bought a Sleep O2 ring and premium membership to try it out but that's not necessary to start with. Hope that helps.
wondering about this: I have a heart rate / 02 monitor on my watch. It sometimes shows a steep drop - sometimes down to 70 but then right back up to normal a couple minutes later. Would this be more of a central rather than obstructive? Also separate of that - I sometimes wake up because while I can breathe in through my nose, I can not breathe out through nose and have to exhale through mouth. This is only occasional but worrisome.
Hello Doc. I found out my AHI is 83 from sleep study without CPAP. AHI is less than 5 when I'm on 14 pressure setting. I have been prescribed with this setting but I often wake up middle of the night with pulse rate around 90 to 100 bpm. I saw my sleep doctor and he is saying I'm sleeping fine and cpap machine is showing AHI of 0.3. I don't understand whats waking me up middle of the night.
So how can one get a graph like this? I can't go for sleep study to the hospital all the time. They gave me a study kit for home use for one night and i got a cpap machine. But is there another device which can give me more details of my sleep?
Hi doc! Thanx for this video. If paradoxical breathing is at 85, 8%, flow limitation at 27%, and snore at 37%, but AHI normal (1.3), what would that indicate? UARS?
hahaha, very hard to tell from just that, but yes it does point to UARS. there is definitely something going on with all that paradoxical breathing. get someone to look at it closely for you
@@VikVeerENTSurgeon thank you! I am super confuesd, and is just trying to learn as much as possible. Your video really helped. The sleep technician has marked the study "normal respiration", and they can't help due to norml AHI. Did recommend med to seek private help though, so that's next on the list. Again, thank you
If only all doctors explained so well.
my pleasure
Your videos are just fantastic. I’ve learnt so much from them. I think your delivery style is excellent: concise, clear, easy to understand and enjoyable. Thank you so much for providing them free for us to benefit from them.
I really appreciate Dr.Veer’s videos. I believe his approach is comprehensive and holistic. My one criticism is background music. I really don’t understand why so many utubers use so much overbearing and distracting background music, I wish somehow this annoying and increasing trend would stop.
You are a rarity person with great sensitivity and compassion, this information is so well explain and important for the user how most of the time can’t interpret all this medical graphics, thank you so much.
Wonderful video. Truly. I'm going to ask my Dr for the raw data as he was seemingly only concerned with AHI. Clearly, that is not telling the story. I found your data breakdowns very easy to understand and follow. Great job, great video.
Brilliant. Just had my report back from my specialist in France. I was able to understand my report which was in french. And when I spoke to my guy I was able to show him I understood. So you really saved the day. A thousand thank yous. Waiting to get my CPAP machine fitted and I will DEFINITELY persevere and win through with this as I now understand my scores of moderate IAH 22 and IDO 13.3. Plus all the detailed data....well almost all of the stats.❤
Thank you so much for posting this. My AHI was 67, now it's under 2, thanks to my CPAP. My sleep clinic has been unable to see me and explained this, due to covid. When face to face appointment resume, I'll have some insight, when this is explained to me. So thank you again.
Oh my God, Thank you so much for this video. It's because of videos like this and people like you that internet is the treasure trove of knowledge that it is. You have no idea how much this video has helped me. 🙏 Thank you so much.
This level of information is exactly what needs to get out, because most doctors either keep this information away from us patients, or may not know everything themselves even.
The discussion at 7:20, about AHI relative to sleep position, is so overlooked at yet so critical. It is great evidence for multiple night studies. Having data from a single night is like monitoring someones driving for one day and deciding they never speed because they happened to not drive anywhere that day.
Thank you, Dr. Veer. I wish all sleep medicine doctors took the time to explain sleep studies to their patients as thoroughly as you do.
I'm impressed by a Dr who gets straight to the point,a very well explained post too,thank you Dr Vic
My first sleep study oxygen reading was 77%. Alarming! But I only had 9 events per hour. That was about 3 years ago. I was first given CPAP, then about 18 months later, BIPAP. Last year, I stopped using my machine for months. After that, a new sleep study by a new doctor: 15 events per hour, 95% oxygen. He put me back on CPAP. I honestly don’t notice a difference sleeping with the machine or without it. I am 68 years old and 20 pounds overweight, working on weight reduction. Last year, I lost 30+ pounds. Thank you for these great videos. Best wishes from Michigan, USA. Side note: I was sleeping in great pain for a couple of years due to osteoarthritis in both hips. I never got a good night’s sleep. I had my hips replaced last year and that has made a tremendous amount of difference in the quality of my sleep.
I had almost 500 episodes (over 100 a hr) and 40% oxygen. Made me sooooo scared for myself.. I'm only 26
Now you use cpap or not?
Thanks!
that was ever so kind of you. many thanks.
Thank you so much
I am technician of sleep study from India🇮🇳
I now understand my sleep study better thank you - I was going to give up on the cpap it’s been a frustrating journey however now appreciating how serious my Q2 dropping to 60% during my rem sleep I’m going to persevere in finding a mask I can wear all night
You have no idea how happy this comment made me. Thank you!
Incidentally REM OSA is often related to the tongue falling back. Try wearing a woodyknows backpack (see video on positional sleep apnoea), with a chin strap (see the Knightsbridge dual strap video on it), and a Philips dreamwear nasal cushions (it'll normally fit on any CPAP machine). Use all that and see if your O2 still drops after 3 weeks (takes time for you to get comfortable and to notice the benefit).
REM OSA also causes a lot of brain fog and that takes time to clear too.
With time you should be able to stop using the backpack and the chin strap (6 weeks or so?).
If you are still struggling consider a MAD with all of that and then see if you still have drops occurring. If not wait the 3 weeks for you to pay back your sleep debt and start removing things until you are just on the mask.
Sorry I can't explain it all to you, but ask your sleep lab and they will explain why it'll work and what order to stop using everything. They will be able to see from the sleep data to guide you.
Good luck.
@@VikVeerENTSurgeon you are a gift to all of us - thank you for your detailed response and recommendations- I have not been very happy with my sleep lab the after care has not been great so I saw a different sleep technician who was recommended to me by a friend - she explained my sleep report in detail - also adjusted the pressure level on my cpap machine from 4-6 to 5-9, changed the humidity level and provided me with a different hose that provides warm air and a Resmed nasal cushion mask. I told her I was a mouth breather she explained we often breathe through the mouth because we’re snoring - i trialled the nasal cushion last night without the chin strap I lasted 6 hours and I had 1.4 events per hour, which I think is pretty good as my AHI in the sleep study was 24 I typically sleep on my left side but appreciate I change positions throughout the night- i so wish I could have a consultation with you here in Sydney Australia :)
Thank you. I had two studies done and never seen either one of them.
Thank you! This has been really helpful for talking to my sleep doctor and advocating for myself
Great video. Was so good to be able to read my own sleep study 👍
Thank you so much for this video! It made sense and now I feel prepared to go to my sleep study follow up appointment tomorrow, where I'll learn my own results. I appreciate your time and help!
EXCELLENT!! After diligently (emphasis ) CPAPing for 5 years - I was ready THIS video. Thanks. Peace
Thank you so much, doctor. This is something even the specialist I went to has probably missed.
100%... I no longer use the resmed app or engage a sleep tech. I use sleep HQ to review my sleep data from my Airsense 10. I used an o2 ring to check my oxygen which was normal during sleep. I ended up needing a travel pillow because my jaw falls backwards when I sleep and now with APAP and the pillow my AHI is on average less than 1 and that's on my back. The reason I mention this is because my sleep study report had a lot of glaring omissions like 0 supine sleep data which I really needed in order to properly figure out the right treatment for me so it's definitely worth educating yourself and take ownership of your own therapy.
Brilliant. This was THE BEST explanation!
I was told my AHI was 85.2 and I had no idea what that meant. The first doctor I had when I asked for the info said I would not understand it anyway so he refused. My 2nd doctor at least is more into communication and working as a team with the patient. I am in Canada. Watching this video makes me want to learn how to read my chart as I really am as bad as the lady at the sleep clinic said I was wow!!!
Love this more technical video. keep bring them on.
My O2 dropped to 46%. I don't know how I am not clinically brain dead after not knowing I had sleep apnea for years.
Thats tough. Hope you aRe doing better now
Holy cow, I’ve learned a lot as a health practitioner about sleep studies and have never seen someone desaturate to 46%. You’re right, you are lucky to be alive.
I just got my results and evidently I stopped breathing almost 500times and my oxygen went to 40
Me too around
40% was happening regularly for a long time for me
It got so bad for me
All my body was like in big trouble
It got to where I couldn’t sleep not even 15 minutes
I would sit up and dose without even sleeping for minutes at a time
That all the rest I would get
I think such a low value could be in error
You are helping so many dr I just had a sleep study and this helps so much thank you greatly 🙏
Everyone who sleeps on their back during a sleep study will have apnea. The test is designed for supine sleeping, isn't it? And the study can tell how long you are sleeping and in what position?
I didn't know anyone is actually allowed to sit up. I was almost strapped to the bed in such a way as to not be able to move from a supine position. My report said to sleep on my back less. I don't sleep on my back nor did I sleep as long as they said. I literally slept about 2 hours if that long. It was 3 or 3:30 am when I finally slept and they woke me up about 4:30 or 5. Never got to see the report, didn't talk to the doctor before or after. Someone even marked out the doctor's remarks about me having minimal snoring. And what gets me is there is always a magic rabbit pulled out of the hat when someone does not have apnea bad enough to use Cpap. Oh, yeah, a number somewhere on that report can be used to justify it. AHI, ODI, etc. "Oh, your oxygen dipped for ten minutes during 7 hours of sleep. You need a CPAP stat."
Do y'all have no conscience? Being a sleep doctor must be very lucrative. How many doctors do you compete with? How many hours does someone have to actually sleep for the study to be correctly interpreted? How about that? I was told the amount of time I slept was enough. Two hours of fitful sleeping is enough to diagnose someone? When they are waking up because they don't want to sleep? Because they don't want to sleep in a strange place with electrodes taped to them and lights on?
Are y'all serious?
just for the record, we conduct over 95% of our sleep studies at home, and so people are in their own beds. We provide all the care for free on the NHS, and we ask people to sleep in any position they want.
If that was your experience, you ought to go somewhere else. My job on the NHS is to help people come off CPAP, not get on it.
sounds like you had a terrible time, I don't want you to name and shame the place. just find somewhere different. Good luck, and I hope you get your thing sorted.
@@VikVeerENTSurgeon Not all allow home studies. I was told my case is too complicated
@@VikVeerENTSurgeon I live in Arkansas. Not too many in rural areas and they all want you to go to same sleep doctor. I had to insist on another full study because they just wanted to do the titration again. Yes, it seems like a racket around here. I know what my problem is and getting a doctor to at least check it has been a problem. Doctors here dont like to be questioned especially if they dont know whats going on with a patient.
Brain waves don't lie. They know exactly how long you were asleep & awake. Sleep misconception is very common & people often think they slept a lot less than they actually did. And enough with the sleep field being a racket. People can die from apnea.
@@litwriter1468 can't you go to a private doctor?
During my two sleep apnea studies I couldn't lie in bed as I normally would. I slept almost entirely on my back because I was tied down with massive numbers of data cables. I felt like Gulliver on the beach. Normally I sleep more on my sides because I find it easier to breath that way. The AHI of 80+ was certainly skewed because I was tied down onto my back.
Did you retake the sleep study?
That really sucks. Have you thought about checking out other places? Maybe you could talk to your Dr. about it. The hospital I went to let me sleep in the recliner in the room. I told them that’s how I sleep at home because I can’t lie on my back & sleep I feel like I’m suffocating. Found out I gotta have a bi pap with oxygen.
I had the same thing , old bed with broken springs I couldn't move position... my studies at home were better done. It's never fun in a lab anyway.
I've got a sleep study tomorrow. I hope I get help after the study and not left to cope alone with my sleep problems.
A young man close to me has recently got CPAP machine and has AHI at 105 per hour, which seems alarming when 30 is severe, and none of your examples were anywhere near this high. I'm pretty worried! His mean SPO2 = 92%, CT 90 =14% (don't know what that is?). I will suggest he obtains a full report of the sleep study, which was done at home over just one night a few months back. Thank you for this information and much more on your other videos. Very much appreciated
My AHI was 102, CPAP is working great for me :) Mean SPo2 is his average blood oxygen level. CT90 is the overall amount of time he spent under 90%. My figures were worse than this.
I look forward to more of these technical videos on how to read the CPAP charts! THank you so much!!!!
A brilliant video as always Vik 👍
Thank you. I am now convinced I have upper airway resistance syndrome since I never sleep on my back.
Thank you very much for this, doctor. This is an excellent video.
Glad it was helpful!
Might be the most informative video on yt for real
Thank you for this video. In my new position at work I need to learn how to read a sleep study report. Thank you.
Fantastic and informative video. I hope sleep study administrators have your knowledge, but I'm affraid they may not, and perhaps mis-diagnosing the problem. I've requested my sleep study info so I can review it. thanks again.
Loved the video! Great to be able to appreciate all the different parameters seen in the NOX T3 device and software program. Definitely more thorough than other HSAT devices.
I agree! not really necessary if all you want is CPAP, but kinda essential if you want to consider alternatives
Wow great video! So glad I am subscribed. I wish you were my sleep doctor.
I can't tell you how valuable this video was for me - thank you so much! I've been suffering from feeling like I haven't slept for years. After watching your video, I asked for my sleep study after they only gave me a single number AHI of 13.6. They then sent some summary information but did not include the graphs. I have interpreted the information based on the guidance you gave. Could you please tell me if I'm on the right track. The data they provided was TST=4h 42min, AHI=13.6, 2 obstructive apneas, 3 central apneas, 8 mixed apneas, 8 RERA events, 51 hypopneas, minimum O2 88%, less than 90% for 28min, mean O2 95.9%, 30% TST in supine position AHI=29.1, 70% TST non-supine AHI=7, RDI=15.3. I believe it indicates that I should stop sleeping on my back, and that should substantially help my sleep apnea. The study also indicated mild to moderate snoring but I don't have the graphs to correlate with sleeping position - I will be asking for the graphs. Am I on the right track? A slumber bumper will probably help me correct? What should I make of the 8 RERA and 15.3 RDI? Not sure what they mean. I've also started your exercises. Thanks again for this amazing video!
BTW, the only thing the sleep doctor told me was my AHI was 13.6 and I could probably benefit from CPAP. I tried and could not tolerate it because my nose is always congested. I wish she would have gone through my study as you took us through the samples. Would have saved me a lot of aggravation!!
Really hard for me to give you advice based on this, but my guess is that you have OSA when sleeping on your back, and then UARS (see video on this), when sleeping on your side. I would say that sleeping on your side (slumberbump is a good product - but i'm yet to review it), is a good idea. Also think about a Mandibular Advancement Device (trying to do that video too). Sorry I can't be any less vague. I hope it helps anyway.
Thank you Dr. Veer. Could I ask what part of the data makes you guess that UARS could also be involved?
It's OK, I got the answer by watching your UARS video. I see that it's tied to RERA. Thanks again!
Very good explanation 👍 I wonder why the doctor that analyzed the data, did not mention that I have almost zero obstructive apneas (1.2/h) when I am on non-supine positions 🤔
This is why I try to sleep on my stomach....of course that produces other stuff (back problems)!
Just amazingly clear and informative!!
Very informative video. Thanks. I was just diagnosed with sleep apnea. I got the results of my sleep result today. Apparently I'm almost triple severe! My AHI was 85 with an average oxygen level of 85 as well. They just put in an order for my CPAP SO waiting for the call.
Pretty hard to roll on side when all wired up!
Learning so much have been using a APAP for over 20 years
Where was this guy when my doctor was insisting that I needed a CPAP and couldn't understand why it was making my sleep worse.
Thanks for this video. Perhaps the main shortfall with AHI scores is that they relate only to the frequency of stop breathing events, with no consideration for duration. Paradoxically, persons with extremely long events ( say more than a minute ), may have only modest AHI scores.
Thank you so so so much for your content
If all doctors had your mindset.
Mine just handed me over the analysis with zero explanation. 😢thank you
Great video! My sleep studies have no RIP Phase or Flow Limitations data :(. My severe sleep apnea seemed 'fixed' after some surgeries because the AHI was around 5. But the RDI was around 15 and oxygen levels dropped to less than 88% for about 32 mins. I still feel very tired and this has a toll on my mental health but some doctors just dismiss it seeing the AHI alone. Would you say that the RDI and oxygen levels I mentioned explain what I feel? If only my sleep study had RIP Phase and Flow limitation data!
It sounds very plausible. Do speak to someone who will look at it properly for you. - have a look at this video which I think might help you. - ruclips.net/video/sa9zNYpTWlM/видео.html
Thank you very much for the technical insight, I hope to employ this analysis on a second sleep study soon. I had a sleep study done several years ago and relate very much to the last case you mentioned - having the symptoms of sleep apnea but being told there's no problem, and suspecting I have UARS at least.
This is fantastic, thanks! Unfortunately, my sleep study was less detailed than the examples you looked at. It didn't break out apneas versus hypopneas, for example, and didn't show what body positions were associated with which apneas/hypopneas. Maybe this is because I did the sleep study at home with WatchPAT?
Daniel Jackson, they all show this, they might not have shown you the data, ask your dr for the full report.
Oh sorry now I see you said watchpat. Watchpat got approved on a wink and a nod. Do it again with a good lab. I high cpap reviw channel covered how they were approved and why it shouldn't have been
Wow, thank you sir ! Fantastic video!
So fascinating. I just looked at my trst results and realized I only had hypopnoeas, especially on my back. Im a week into CPAP and I am starting to feel better despite struggling to get used to the equipment.
Thank you very much for explaining all this.
Doctors now dont have time for a patient to give them this valuable information, they concern about achieving targets.
Thank you Dr Vik
AHI = 23 😔
Very useful video. Thank you!
That's awesome Doc. Thanks
Hi Mr Veer,
Just a quick question to pick your brain if I may! What would you say that constitutes 'normal' or non sleep apnea metrics on a sleep study? Is it a certain AHI, say 5, in the most vulnerable sleep position for OSA, or stability of oxygenation etc Many thanks if you can assist.
Matt b, 5 and under is considered normal for ahi but watch lanky lefty's videos, he says you shouldn't go by the ahi number. (Mine was 5.9 with a mandibular device they told me it was minimal but I was having spo2 at 82-85% for 2 hrs a night - def not ok).
I have extreme sleep apnea but before i got tested i had recorded my snoring, The recordings show clearly the apneas where I do not breath for a bit then load snoring when I do, but when it gives an overall rating for the snoring it says it is not very loud, and that is because it basically averages the whole night, and if I spend 50% of the night not breathing(yes it was that severe) then that 50 of the night I am not making any noise.
Guess when you have a AHI of 58 and sleep exclusively on your side you should have a PAP machine...
This is gold
I just purchased a Sleep O2 ring which measures sleeping O2 and heart rate from Sleep HQ which I can upload with my Cpap data. It aligns with the data. It's not cheap - requires premium membership- but I'm fed up trying to get data/analysis from the doctor. Cannot get my Fitbit which measures these to connect to the Fitbit app- very frustrating. Hoping I can plan better management. I think sleep medicine is easy money for many docs. The techs don't even tell you the data can be obtained from your machine when asked.
Hi Dr Vik, I have a deviated septum and severely blocked nose most of the time leading me to mouth breathe as I physically cannot through my nose, can this contribute the sleep apnea?
Sort of... Nasal obstruction makes sleep apnoea harder to treat, but doesn't cause sleep apnoea on its own. Sorry for being vague - it's actually quite complicated.
So informative. Thanks Vik.
Glad you enjoyed it!
Thanks very much for posting this doctor. I had a sleep study performed a few months back on the N.H.S, but have still not heard anything because of some sort of backlog. I might try asking them to send me the results in the meantime. Are the results something that would be produced immediately? And so am I just waiting for interpretation? Thanks.
No, it needs to be validated, sorry.
@@VikVeerENTSurgeon Thanks for reply Doctor 👍
Thank you so much for this video! I was diagnosed with mild REM related OSA and mild positional apnea. Oxygen dropped to 85% at one point, and pulse rose to 120 bpm but in both of those instances the report says “excluded periods” for respiratory periods. So I don’t know what to make of them. Total AHI is 5 and total RDI is 28. It was a home study so I don’t have some of the other useful data. Could this point to UARS if I’m experiencing gasping events regularly on my back and yet numbers seem too low for OSA? Would a mandibular device be a good start? They want me on a cpap but I am unsure.
it is pointing to UARS - but that report sounds like it came from a WatchPat device? Might be worth doing a more complete study like on a NoxT3. I think a Mandibular Advancement Device would be a great idea.
I have mild sleep apnea. Pretty much a zombie with pseudo arthritis when left untreated so the term mild is pretty bullshit to me but that's another story. Anyway, mandibular works well for mild. I just graduated engineering and couldn't have done it without my mandibular. The cpap didn't give me the same energy boost the mandibular did.
Hi Dr. Veer - I'm wondering if you have an opinion about the various Home Sleep Test devices currently available. It seems like there is a trend toward smaller / disposable devices (like WatchPat and NightOwl) which rely more on complex tech / algorithms to "estimate" apnea events and sleep architecture. Do you think the Nox T3 (now T3s) is a better device to collect the kind of data necessary to diagnose UARS, for example?
Hi Dr. Veer, for apnea/hypopnea, do u know why they decided on the number 10 seconds as the magical number? For ex, what if a patient had events that were like 7-9 seconds, wouldn't they still be significant? However, they would not be counted because the event was not over 10 seconds....
you are right, it's a bit rubbish. most of us just look for arousals and dips in oxygen / effort in breathing. we don't count the seconds. that's why you need a good sleep study equipment. otherwise you are likely to get an unrepresentative result.
@@VikVeerENTSurgeon Ahh i see, makes sense. Thanks for your reply.
@@VikVeerENTSurgeon Also, a general question for you if u don't mind. Do sleep doctors account for the fact that patient's don't sleep well or like they normally do at home for in-lab studies? Like the first night effect, i feel sleep inlabs is not as "bad" as it would be for patients at home due to sort of being more alert in a new environment.
The reason i am asking is because I know for my in-lab, i feel my sleep was not representative of my sleep at home at all. I had such a hard time falling asleep, possibly due to new environment/setting/wires/ being nervous/anxious or something. And then i also woke up in the middle and again had trouble sleeping. This is never the case for me. I'm usually out cold around 11-12 and up at 7-8 AM. And sleep the whole way thru. I actually feel like i barely slept for my inlab study. I recall being awake/alert for a large part of the study, which became increasingly frustrating mentally as i knew this was very important for me diagnostically.
I feel my in lab study resulted in data that was falsely lower than it would have been had i slept like I normally do. I also had less reduced REM sleep (most of my events were in REM sleep), also making me think had I had more REM sleep my AHI would have been higher. I had an AHI of 6.5 but my sleep doc says i'm fine and don't need tx, despite complaints of classical symptoms such as morning headaches, brain fog/cognitive issues, poor unrefreshing sleep.
I also saw your video on UARS. I'm just a person trying to get proper good quality sleep. And not have horrible morning headaches. I'm assuming due to my results, they feel i'm on the lower side and don't really need a cpap machine. I feel it doesn't hurt to try, perhaps it would resolve my symptoms. Maybe there are better ways to navigate this, but as a patient and layman, it's hard to know what to do. Any thoughts would be appreciated. thanks again.
If you are worried about a sleep disorder then an in hospital PSG is required. if you are just worried about a breathing disorder (like OSA or UARS etc), then a home study I think is superior. you can do everything at home except have the video on you but we aren't interested in epilepsy or sleep walking etc. I would have a PSG at home.
@@VikVeerENTSurgeon ahh i see. Thank you for response. Also, if you don't mind, what's your thoughts on cpap treatment for mild sleep apnea or UARS. I read varying things, some sources state benefit isn't so great unless one has closer to moderate or severe apnea. For me, the biggest thing is the horrible morning headaches, cognitive issues, and somewhat feeling drowsy. I think its mostly a breathing issue but I feel i'm on the milder side or a case of UARS. Wondering if cpap can still provide benefit.
I have 2 sleep reports with NoxT3s - one before and one after throat surgery.. What are the chances you can view these and comment.. My snoring went down but AHI increased after surgery.... love your videos btw - so good to have someone explain these things!
What abou AHI and RDI values during REM sleep and The same values for overall sleep? Which are the ones important to look for... to classify the sleep Apnea case?
I have tried two at home sleep studies and I couldn’t sleep either time, I tried for a week straight with both and my dr said there almost no data on my sleep and would have to do it again. Not sure what to do but try and get a referral for an ent and hope they have some answers, I am so completely wiped out almost every day!
Thank you very much for the video. Would it be possible for you to do one focused solemnly on Central Sleep Apnea with the analysis of the sleep study? It would be important to also learn about the different types of apneas, beyond the obstructive.
I'd appreciate a central sleep apnea video as well.
I wonder if he could do that since he’s a surgeon. Centrally mediated sleep apnoea probably has no surgical solutions or treatments
Typically what is the difference between central and obstructive?
I had an apnea while lying down awake is that even possible?
Hi Dr, thanks again for a very helpful vid. So one assumes the NoxT3 software only works with the initial test results and not with the Resmed Airsense 11 software? Im using Oscar to read this software and under Flow rate it often has multiple clear airways.....can I ask what is clear airways?
you are a star. Oh just found another one of your Vid and am I talking about UARS?
Super helpful. Thank you
Brilliant Video Dr Veer thank you
Hey man if you see this it would mean the world… Do you think it would be possible for someone to be mis diagnosed with Narcolepsy type 2 but instead have UARS? I had a sleep study done that was normal with apnea’s but never truly aligned myself with the symptoms of narcolepsy. God bless
I guess it's possible, but it would be odd for a sleep doctor to get them mixed up. get someone to video you whilst sleeping - if you are breathing really heavily, it might be worth looking into it again.
@@VikVeerENTSurgeon tysm man, during my sleep study they recorded me but my father slept in the same room because I was a minor at the time. He snores pretty loudly so Idk how they would of noticed my noises over his.. Appreciate it so much. Thinking of doing another one now that i’m older to be sure.
@@VikVeerENTSurgeon even if Rdi and Ahi was normal?
I need you as my dr.. i literally feel like im dying or having a stroke most days if I dont have a perfect sleep. Drs havent helped me and sleep dr simply rebooked a sleep study 4 WHOLE months later.. i literally am afraid to drive in case I crash.. dont know what to do but thankfully my brother had a sleep apnea machine to lend me. Just havent been able to sleep with it yet.. I want to get surgeries and a dental device to bring lower jaw forward. I also have a deviated septum which no dr seems to have noticed yet or care about.
Dr.Vik ,I need your help. Please kindly assessed my situation.
Thank you for these insights. Could you share some information on how these polygraphs technically work? Reason of asking is that the sot polygraph records 6h of sleep while im almost certain i slept significantly less. How does the device register i am sleeping and how accurate is this?
Possible to do a video on interpreting a RBD report?
Is flow limitation the same as the Desaturation Index ?
No, very different
Dr. Veer, can you get RERA's in a sleep study from a chronically blocked nose?
Errrr.... I guess. It depends on the equipment and how blocked you are. It isn't meant to pick this up, but it can confuse the readings if you have a blocked nose. vague answer I know, but it's quite complicated. Sorry!
What is unclassified tachycardia?
I've heard RDI is a much more useful metric than AHI. RERAs aren't as bad as hypopneas, and hypopneas aren't as bad as apneas, but they're all still bad. I'm getting oxygen desaturations, loads of flow limitations and RERAs, and nobody in Canada will even acknowledge there's a problem because my AHI is low, so I don't know what to do.
Fellow Canuck. Suggest you follow Sleephq channel. He's a sleep tech in Australia who has sleep apnea. He has developed a tool to upload your data - like OSCAR. You can keep one month data for free. He has lots of great videos and is very responsive to questions. I just bought a Sleep O2 ring and premium membership to try it out but that's not necessary to start with. Hope that helps.
Excellent
Which sleep study is this taken from. I used a watchpat one. What’s your opinion on one of these ?
Mr Veer . I have mild positional sleep apnoea. Can you please review electronic positional device .Thanks
How can you spot central sleep Hypopnea ?
AHI
wondering about this: I have a heart rate / 02 monitor on my watch. It sometimes shows a steep drop - sometimes down to 70 but then right back up to normal a couple minutes later. Would this be more of a central rather than obstructive? Also separate of that - I sometimes wake up because while I can breathe in through my nose, I can not breathe out through nose and have to exhale through mouth. This is only occasional but worrisome.
Hello Doc. I found out my AHI is 83 from sleep study without CPAP. AHI is less than 5 when I'm on 14 pressure setting. I have been prescribed with this setting but I often wake up middle of the night with pulse rate around 90 to 100 bpm. I saw my sleep doctor and he is saying I'm sleeping fine and cpap machine is showing AHI of 0.3. I don't understand whats waking me up middle of the night.
You need an in hospital PSG with EEG and video etc. That will explain why you wake up despite not having a breathing issue.
Hi Sajid, how is your health now? I have similar problem and wake up multiple times in the night. What helped you resolve this issue? Pls help
So how can one get a graph like this? I can't go for sleep study to the hospital all the time. They gave me a study kit for home use for one night and i got a cpap machine. But is there another device which can give me more details of my sleep?
How do you feel about at-home sleep studies?
I dont see how under 5 AHI is good. Mine is usually 1-2 AHI on an APAP 2nd week in and I only feel more tired in another way.
I wonder if I could email you the results of 3 sleep studies of mine
Hi doc! Thanx for this video. If paradoxical breathing is at 85, 8%, flow limitation at 27%, and snore at 37%, but AHI normal (1.3), what would that indicate? UARS?
hahaha, very hard to tell from just that, but yes it does point to UARS. there is definitely something going on with all that paradoxical breathing. get someone to look at it closely for you
@@VikVeerENTSurgeon thank you! I am super confuesd, and is just trying to learn as much as possible. Your video really helped. The sleep technician has marked the study "normal respiration", and they can't help due to norml AHI. Did recommend med to seek private help though, so that's next on the list. Again, thank you
I have more ahi events in the non supine position than the supine. Is this unusual?
