Uncle Nicko
We all use the AHI (Apnea-Hypopnea Index) calculated by the CPAP machine to guide our CPAP therapy. We all assume it's accurate. It's not. Sometimes it's not even in the ballpark.
The American Academy of Sleep Medicine (AASM) recommends hypopneas be defined based on a ≥ 30% decrease in airflow for 10 seconds or more with some additional criteria included. It's the definition most specialists & sleep techs use when analysing diagnostic sleep studies.
ResMed (and other manufacturers) have increased the threshold from 30% to 50%. They've also stated hypopneas without flow limitation are not scored as they typically do not result in oxygen desaturation or arousal. I'm calling BS on that. It's almost like they don't want to flag events.
So unless there's a 50% reduction in your airflow, ResMed doesn't think it's worth flagging. It doesn't meet the 'criteria'. You could be having hundreds of 40% drops a night just like Joe, severely affecting your sleep quality, and you wouldn't even know! Although, you'd probably feel pretty shit during the day, which many of you are reporting.
Perhaps, and this is pure speculation. The manufacturers have set these high 50% thresholds, so the machines have an excellent probability of calculating an AHI under 5? It would be fascinating to see those MyAir app scores change if they dropped to 30%, as recommended by the AASM.
In all honesty, I don't like the AHI number. It's a 'standardised' number that isn't standard, often misleading. I'll give you an example. You could have someone with an AHI of 30 who has SEVERE APNEA. That person might have mostly 10-second hypopneas with mild 3% oxygen desaturations. Another person might have an AHI of 10, classified as mild, yet they have 1 minute long apneas with oxygen levels dropping to 50%. I would argue that severe apnea is the AHI of 10 in this scenario. There are many shades of grey, and this 'one size fits all approach to diagnosis and treatment needs a rethink.
sleephq.com is now available for ResMed AirSense 10 or 11 users. It's super easy to upload, review and share your cpap therapy data charts.

I really love your videos and their informational quality. I purchased my BiPAP machine (went online and got it in less than a week because the DME said it would take them at least 4 months), and I'm getting AHIs and CAIs in the 40s (I'm getting used to the high pressure settings with the lower ones I put in. Thank you by the way, the first night felt like my lungs had been put through the ringer with high settings, and your tips are allowing me to build up to my correct settings). Frequently when I'm reaching early stages of sleep I can actually tell that I'm having an event as my body isn't getting the reminder to breath. I check my machine by stopping it and looking at the reports and it picked up an event.
You're doing such an important job, and doing it very good. You helped me a lot in the past few weeks - before and after I started cpap therapy. Thank you so much !!!
Awesome mate! Thanks for the great feedback Good luck with your therapy. Nicko
Just got my machine yesterday after a 4week trial. Your vids are invaluable and in fact people at the cpap clinic said they watch your vids too! Have now signed up to sleephq and checking it out. Cheers mate
This is the best explanation of flow rate and what I need to be looking for in Oscar. It's no wonder that I'm consistently way under 5 AHI but not sleeping well every night. Thanks mate!!
Great stuff brother. Let me know how you go
I can't begin to tell you how much I've enjoyed your videos! They've Really helped me in my quest to get my AHI's within a reasonable range. I currently use a Dreamstation 2 and don't currently have any access to reports other than what is provided by Phillips. Even so, This video(Along your other videos) have been a HUGE benefit to me!
THANKS !
Hi Dwight, thanks for the lovely comment mate. Great to hear you're enjoying the channel. All the best. Nicko
Phillips RECALLED due to patients inhaling particles breaking off of the machine. UNETHICAL!!
It is obvious the manufacturers want to make their machines look good rather than help patients the most possible. Thank you for your videos. I am very glad I found your channel.
I think that's probably part of it also. Thanks for your comment my friend. Nicko
Probably the hard truth keeps people awake too .. 😂
Outstanding content! I have learned soooo much from you. Pressure adjustments, the menu behind the menu and so much more. Thank you, keep up the good work! I may be able to get used to this machine after all
Wow you are amazing. The NHS sent me home with a CPAP 3 years ago. Apart from a couple of phone calls I’ve had no other support.
Hi Luke, that's very kind of you to say. Glad it helped. Best wishes. Nicko
@@CPAPReviews you
Sounds exactly like my story and many others… Absolutely horrible…
Huh.
What a breath of fresh air you are.
A new paradigm in my experience.
Can't really say I'm dissatisfied with my Resmed and support program.
Even with my collection of allergies clogging my sinus, 24/7.
Loved your delivery, and the little Bean thumbnail. Don't ever change, please carry on! 😎
Hi Dana, thanks for the lovely comment. It made my day. Best wishes my friend
Thank you for you for what you're doing. I find your platform SleepHQ very informative and helpful. This video too. I was not aware that my Dreamstation keeps records of every my single breathe and could be viewed as timeline graphic. Really nice job!
I firstly tried a china cpap machine Reswell which reported AHI about 15 or so, while Philips Dreamstation reports always below 5. Now I have a logical explanation of this discrepancy.
Thanks for sharing your insights mate. Nicko
No doctor has EVER explained or even mentioned this data. Just “bring your machine in” and we will download it. I now have a Resmed which transmits data but never been told anything. So upset because other than asking for my pressure to be reduced there have never been any changes made. I have started to wonder if this is just another way for them to make money, not to really help anyone.
Just watched this last night. I opened an account at sleep hq. I started cpap in june of this year. I am still not sleeping, and it's taking a toll on my life. I was diagnosed as mild sleep apnea of 14. I have been consistently under 5 ahi, really since starting cpap. Yet i can't sleep through the night and wake up exhausted. I made some adjustments last night after watching this, and i tried using some mouth tape. It's hard because i have a goatee. But i managed to get it on, and it stayed most of the night. My ahi was 0.47 and went down .19
My leak rate was 4.8 down 3.6
My pressure is set from 7 to 11. Humidity 4 and epr on 2. I use airsense 11 and nasal pillows.
It seems from the data i should be sleeping like a baby. But looking at the saw tooth breathing says a different story after rewatching this video. I will not give up! I do hope i have a breakthrough soon brefore a breakdown!
Ware a mouth strap
.taping mouth is dangerous I believe..
@@vibes..585 Tried mouth strap didn't work. Mouth taping helps and not dangerous. It is a light glue easily removed. My brain would wake me up if I were suffocating just like it did before I started using cpap. Thanks for your suggestion!
Praying for your brother, you'll solve this. I'm also fighting sleep apnea but yeah I'll solve it soon 😁
Btw have you tried upping the pressure setting till you feel you're sleeping better?
@vicaccino I've actually lowered it. I looked at sleep hq and oscar data and adjusted in a tight range of where the pressure is 95% of the time. Much better, but even better with mouth tape.
What an excellent presenter. Thank you.
Hi Brian, thanks for the lovely comment. Best wishes. Nick
Great video mate. As an interesting follow up I would look at a WatchPat, or other sleep study auto report. I have found that these studies over report AHI (mark each event multiple times), so that it makes you look worse than you really are. Then they get you on CPAP and give you artificially low readings.
Brother! Great to hear from you. I don't think we have the WatchPAT down under but i had a look at it. I think if i venture down the diagnostic rabbit hole i might never come back up . It's a great point you make though. So many businesses doing home sleep studies, it's really not hard to artificially report a high AHI during the study and then sell them a pap. Keep up the fantastic work with the youtube channel. Nicko
Nice to see you around Dr. Veer! Wanted to mention that I've actually been told, and experienced first-hand, WatchPAT underreporting AHI rather than overreporting. Perhaps this is due to the nature of my AHI being mainly hypopneas with microarousal but very little oxygen desaturation. My recent in-lab picked these up giving 11 AHI overall and 17 during REM, while WatchPAT AHI was around 0.
When it comes to your own health, you have to take control. It's ultimately up to you. Thank you for this. Doctor was saying things were fine, but I didn't feel fine at all.
G'day, great comment. I think that phrase 'trust but verify' can be applied to all aspects of health (and life!). Cheers
hoping my doc can fix me not breathing and my shallow breathing. along with the pins and needles
@@chazzthaspazz4475 Pins and needles? Please explain cuz for like two years i experienced pins and needles in my skin mostly in the feet, legs and hands. Even in the face sometimes. Was just diagnosed with severe sleep apnea and got a cpap 1 week ago.
Since I've been watching your videos, I have awoke and am being aware of much more of what is going on with my CPAP machine and myself. The doctor never told me anything. Basically he just told me I had severe apnea and let me loose. Didn't even tell me where to go to get a machine. Believe me, you have opened my eyes. I have learned so much and have so much more to learn. Thank you so much.
"Since I've been watching your videos, I have awoke and am being aware of much more of what is going on with my CPAP machine and myself."
Same here. I go to see my VA doctor tomorrow and hopefully things go ok and I'll be able to get a newer ResMed CPAP. But if not, I can now maximize the usage of my current AirSense 10.
One of your great videos Nicko! Thanks.
Many thanks brother. Glad you enjoyed it
I love this app! It's solving all of my CPAP problems. Mine was set way too high!
Absolutely tremendous eye-opening video! Very informative and clear. Many thanks for your educational and useful videos!
Hi Andrew. I'm glad you enjoyed it. Lots more to come
I love the way he flipped off his buddy with the O2 sensor ring 😂
I'm just starting my therapy. Going in to the unknown. Thank you very much for puting videos up on RUclips. They are very helpful in understanding what is happening and what to expect.
Me too hows it going
Holy jeez thank you for the info! Videos are concise and very appreciated.
Most welcome Brian
I'm a rpsgt and I really appreciate this video. My hubby is still exhausted after 5 yrs on cpap. I will check his data. I recently got dx'd with osa and I will start checking mine, too.
Awesome! Glad you enjoyed the vid
Your the greatest Nick, thanks
This was eye opening- thank you for this. My AHI is consistently
Hi Chad, you're welcome. Glad to hear you're enjoying sleephq. Cheers
So did you ever change your settings?
incredibly timely video. was having some really rough days with fatigue this week. put the data from the airsense 10 into sleephq and it looks like theres alot of events that arent flagged. might bump the pressure up a little and see how i go. the tight range auto setting idea is a good one too.
Awesome mate! Let me know how you go
Thank you for telling me about OSCAR. I have download OSCAR to my computer and it works
fantastic.
I use a ResMed S9 ACS-A Pacewave and my AHI 7 day average is 0,15. I use the machine 8 hours a night.
I am 74 Years old and I am a CPAP user since 2005. Starting with ResMed S8.
I got the S9 ACS-A cheap a Year ago and it is 100 times better than the regular S9 CPAP I used before.
You're welcome mate
Eye opening. Now it makes sense why with 99%compliance I still feel like I am exhausted. Even went to a nose Dr that gave me a surgery that opened the passage way through my nose. I feel like I breathe better but am still exhausted. Tried new bed new pillows. This is the first time hearing about the flow rate of breathing. Thank you
G'day Sam, compliance will get you 50% of the way mate and the other 50% is the right therapy mode / pressure settings and mask fit. Cheers
Tonight is my first night of my 3B cpap machine…
I watched your videos part one and part two of how to set it up and I went in and changed numbers around to the numbers you suggested for beginners now I’m scared to use it…
I’m thinking I probably should not have done that because maybe my doctor had it already set to a certain number..?!?!?
could someone please please tell me
I’m literally scared to go to sleep and use this as I said it would be my first night I just don’t want to not wake up
Supposedly I have “severe” apnea that is what is marked on my papers that she sent me home with apparently I woke up 42 times in one hour
So this again goes to what you said in one of your previous videos, besides what the machine is telling you, you can go by how you feeling. If still feeling tired, add an 1 additional pressure and see how you feel. Thanks Nick for your help, you rock.
G'day mate, great comment although i'll just add that sometimes it's not all about adding pressure which you will see in an upcoming video. Stay tuned
@@CPAPReviews oh man can't wait, thanks for your reply, have a wonderful day.
Thanks, had a dream station (DS), now resmed, after the motor foam problem. Set pressures, started on nine, AHI around 6, up to ten, AHI .09-1.5 mostly. Last test Doc recommended drop to seven. Three days of C Crap, so I'll take it back up. One thing I did like about the DS, break apart for short term travel.
I use the Wellue ring along with CPAP and it’s awesome. It wakes me when my SP02 drops. It’s helped immensely!
love it mate
As always Nick. Great video's with Great advise for us all. Thank you for keeping us all informed. Hopefully you will have some BMC machines on the the Sleep HQ site in the near future.
Hi Chris, We're doing F&P now and then BMC will follow. Thanks mate
@@CPAPReviews Thanks again Nick. Good to hear as my BMC Luna hardly ever registers any AHI events. Will be great to be able to see if results are accurate or not.
Now I want to watch the Matrix series again. LOL. But thank you for the great videos. Looking at the larger range of data in SleepHQ is awesome and your videos explaining how to look at different things within your data and small recommendations that can help correct and improve the limitations inherent to the CPAP machines is really helping me get my machine set back up after it's settings reverting back to default since it's been unplugged and not used for an extended time and I rolled off of being eligible for support from the sleep clinic and have to go back thru my normal doc if I want to go beyond monitoring it myself or for new sleep study. Looking at the AHI index my changes had been looking very good. After watching a few more vids and looking closer at other areas of the data I have more work to do. Thank You so much for sharing your knowledge and making these videos.
Hi there, what a great comment! Glad you're enjoying the platform . Keep up the great work
Great analysis this is so helpful
Thanks, Nick. Superb information. I have to give Sleep HQ a try.
Awesome mate, yeah absolutely! Certainly lots of cpap users on the platform checkout their therapy performance. Should also see lots of cool new features in the near future. Cheers bro. Nicko
Thanks for the amazing video!
You're welcome brother. Thanks for your support
Absolutely golden information Nicko. Thank you.......just gotta get an o2 ring from ya.
Cheers brother. Absolutely! I'm working on a brand new iphone app right now and it's nearly done. Cheers
Great information 👍 Thank you 👏
A most excellent video, thank you
Glad it was helpful!
Thank you, very clear!
Great stuff. Glad you enjoyed it
This was so informative. I look and my data and don’t have a clue what it means. Hope you continue to make the explanatory videos.
Hi Doreen, glad you liked it my friend. I certainly will!
Thank you, that was eye opening!
Glad it was helpful!
Thank you very informative mate.
I've had difficulty understanding what I've been looking at. That was very useful, thanks.
Glad it was helpful! I will be doing a lot more tutorial videos in the near future
Thank you for such an informative video! I have learned more from your videos online than I have from my present and past sleep doctors. Quick question...how commonplace is it in the CPAP world that supplemental oxygen at night is added in addition to using your CPAP...when you are continually waking up not being able to breathe on the machine? Would this be mainly because your CPAP pressure is incorrectly set by the professionals? After listening to this video of yours, I find myself questioning the use of nighttime oxygen vs. tinkering with the pressure to fine-tune it. Any thoughts on pressure vs. supplemental oxygen? Thanks so much!
Sounds like great advice. Thanks.
You bet, thanks Will
incredibly informative !!!!
This needs some more views...
Hi Jake, i'm glad you enjoyed the vid
@@CPAPReviews Messed up tho, because by the CPAP reports coming out like that, it falsely shows higher effectiveness for therapy. They can then show their machines are doing a great job, when in fact, they are not.
This is a particularly good discussion for me. This morning was a good example of what I face in my own therapy: I think I would benefit from a higher upper pressure limit but the mask fit will not hold it.
This morning, I was awakened by my mask leaking - the pressure was blowing past my seal and it would only hold if I got the mask EXACTLY square on my face. This has been true for a long time and what I have had to do is set the upper limit down to stop the problem.
Fortunately, I had enough quality sleep last night that I am OK for the day but you really piqued my interest when you talked about using therapy, thinking everything is OK but still feeling draggy during the day. That is, I have good days and bad days without an apparent cause.
I use a Resmed Airsense 10, Vitera full mask. I wish someone made a mask that really sealed well for my face contours but I fear there is not. Have used the Resmed Quattro, too. Same issues.
I am going to pay more attention to my settings and see if I can adjust around this a little more. Anyone w/ suggestions?
I use the nose mask. It has a smaller ares to leak..
@@KBS117 Thanks very much - for reasons I won't get into here, a nose-only mask just won't work for me...
Great video, very helpful, wasn't really sure how to read that data. I'm using Oscar but SleepHQ looks less messy so I'll check it out. Just had a look at my flow rate. I don't think I'm missing to many apnea events but there are places were my it looks like I'm approaching an apnea event but then recovers. Doesn't go down to the zero line but gets closer. In the past I've used my oximeter and lined up the graph with the data in Oscar and never had to many worries with low oxygen outside of the marked apnea events. But I'm gonna compared the two data sets again for a few nights with this new insight you've given us.
Wow thank you so much Nick
Thank you for the info and Help. Your a great help to us all. I'll set my Cpap to 13 and see how we go.
Sleep Doc tomorrow, Interesting to see what he has to say.
Nice one brother! I'll be very interested to hear about your visit and to check the changes over the coming week. I received your email
@@CPAPReviews Had a bad eye leak (as in just my right eye)last night for the first time, kept waking me up. drop down to 12.6 see how I go tonight. Thank you for all your help I can not say this enough times
Great information. One recommendation may be to change away from the pillows. I used pillows for years and determined that I had trouble exhaling and sometimes inhaling
Thanks for sharing your great insights mate
I used pillows because I have sinus and congestion issues esp when I sleep. I thought it was getting the air in me the best. I wake up though with a heavy chest. Could that be why... I'm struggling too hard? My o2 ring shows my oxygen is good though..always within the range..90s
Fantastic information as always. Off to check the flow rate.
Great stuff Bernie, Glad you enjoyed it brother
That thumbnail is fire! Lol love it. It looks like Morpheus truly is struggling with cpap breathing. One of my favorite movies .
Thank you! It is my fav haha
@@CPAPReviews welcomed !
Excellent video! Thanks for sharing the Sleephq link - I din't know I could access such valuable information from my home PC!
HI David, you're welcome mate! Best wishes my friend
Very valuable information. Thanks
Thanks for your comment Jenny
I'm a new cpap user thankyou for the great information you have explained alot about the cpap machine that should be explained but not
Hi Diane, glad you enjoyed the video. Thanks for watching
Great advice and observation !
Thanks Leanne
I am super impressed with your videos, so helpful, so much significant information presented in such an easy way to understand. I'd love your comments on this situation. I bought a good quality smart watch (Garmin, over $400) to monitor vital stats since I have health problems ... got it before I started the CPAP therapy. The watch gives info on sleep including a general "rating"; I consistently was in the 30's and 40's (rated poor) when it should be in the 90's. Par for the course since I had 25 events per hour in my sleep study. Although my ResMed stats are much better (2.7 last night), my Garmin watch ratings are still "poor" every night. I've been thinking that they must be off since I started the CPAP, but now you've given me another vantage point ... maybe the watch is correct and my ResMed data is off, not reporting numerous events. Hmmm ... what do you think?
Great post . Thank you
Glad you enjoyed it
I was wearing a CPAP machine for 7 years without which I would have died. I started an intermittent fasting regiment along with eating no bread, rice, or sugar. I don't have to wear one anymore. Diet Diet Diet Diet and generalized inflammation!
No sugar at all? Not even fruit?
@@Hsteel no fruit
And no sugar at all. You won’t miss them after a few days.
@@gondishapur just veggies and chicken ok
What foods would you recommend for this diet?
I love your content. Taught me more then my "doc" i'm switching because of this. Mine is complex. I have asthma. But i'm 100 percent adherence. AHI says 0 the report shows the hypnea's . Increase pressure in increments to get my overall well being and sleep good. I'm doing good. but i also noticed my o2 would go down to 88 sometimes. Keep up the good work. i'm only 39 years old. i have a long time to go. i'm now off of blood pressure meds and depression meds for 3 months. My asthma was worse for over a year after covid. Any data out there to see if Covid caused worse sleep apnea after disease? I noticed my wife's apnea has gotten worse.
A very informative review which has opened my eyes further.
Hi Michael, glad you enjoyed it mate.
I really want to take you for sharing this information, it can really save lives!
Glad it was helpful! Cheers
Hi Nick, great video, scary to think its underestimating it. I hope they updated their software. I’m trying to understand my own flow rate. Can you narrow the data range from -150/+150 on the graph so it’s easier to read?
G'day mate, sleephq customisation is something that will be possible in the future but for now that's not an option. Cheers
Awesome video! Thank you from the States
Glad you enjoyed it!
Very interesting Nicko.
Thank you :hell:
As a programmer & mathematician with experience coding signal processing algorithms, I would say it should be easy to write the code to correctly identify the hypopnea events in the examples you showed, without missing so many.
Exactly. Its not that its a human problem, its that the criteria is way too strict. Pattern recognition is within our ability to program for this kinda stuff
Hello, I’m also a programmer , Data Scientist with a Math degree. I agree , since there are degrees, Perhaps they should not be counting each breath as yes or no. They could rate them on a scale of 1-5, or 1-10, Then compute a score. But I am guessing this how they have always done it!!!
@pgerschibm precisely! I am NOT a programmer with a degree, and even I know that this can easily be done and should be flagging by category... 0-20%, 20-30%, 30-40%, 40-50%, 50+%. They only giving HALF of the data with this all or nothing approach. How UNscientific.
@@pgerschibmfor a world that now runs on data, this oversight is ridiculous.
Also very disappointing is the medical community and their disinterest in digging into these issues, and educating their patients properly.
After 6 months using a machine this is what I’ve found. After countless masks and adjustments I can report that I am now sleeping far worse than I ever did before. I am just as tired as I’ve ever been. It takes me eons to fall asleep even when I’m dog tired. I feel like I’ve been sold a very expensive and worthless waste of time.
Very informative, thank you! I started my therapy just a couple of weeks ago. I was so excited that my ResMed myAir app showed I was consistently below 5. Now I'm skeptical because I'm still very tired sometimes during the day.
But I know that I'm still adjusting to therapy and am probably not sleeping deeply.. I'm so glad I found this, as I'm always very proactive in my medical treatments and have learned the hard way not to completely trust Drs without question. Where can I get this O2 ring everyone is talking about?
Did you get an O2 ring?
Got mine off Amazon.. wellvue
Fantastic insight 👏
Glad you think so! Many thanks
Grate video, recently I had some problems with my therapy. as i lost weight i slowly dropped my pressures to stop some bad side effects i.e. wanting to throw up some mornings ect with a API of about 1.5. It was going grate until I got COVID. my API was still low at 7 but this video makes a lot more sense to me on why
Glad you liked it Dan. Thanks brother
That’s so grate mate!
Thanks for the great videos. I’ve been in sleep medicine for about 13yrs and did my Masters in Sydney. I have mostly been scoring but have started back in CPAP consulting so finding your videos great. I did use ASV years ago for centrals but managed to treats the underlying cause but know how important patient based feedback info is. If there is anyway I can help contribute or learn from you I would love to help and learn. I’m RPSGT (used to also be RST) and ANZSSA member.
Keep up the great work!
Good morning,
You mentioned Central Apnea.
How did you find the cause?
Many thanks,
Robert
Thank you. I've got OSCAR, will look at the breathing record and see what it looks like. I am embarrassed to say that EVEN AFTER FOAM-GATE, I've failed to verify or even question the "data" as reported. I'll make time to look it over tomorrow morning.
Thank you for this informational video. SUPER! That is of great help for me, a "non-medical" user, fond of Oscar to give me at least the additional information for the non-information of the Resmed/Dreamstation output. I wonder, will there ever be an Oscar iPad version, using the data available on iCloud?
Hi Peter, you're welcome. I highly doubt it but time will tell. Cheers
Makes sense. My dream station is set at 10 but it will drop some times and raise no higher than a 10 other times. Sometimes I am tired and other times I am ok. I am a back and side sleeper, no perminate position
Key point is 10:44 "So unless your airflow drops by a massive 50% for 10 seconds or more, RESMED doesn't feel there's a problem. They won't flag the events". It is very important to learn the Sleep HQ data, we need to take control of our own data cause it looks like no one else will.
Certainly one of the key points mate. Cheers
Is the 50% drop in airflow for 10 seconds or more a ResMed-specific standard, or is it the general medical standard for defining hypopneas? I've seen similar criteria mentioned in various medical sources unrelated to any specific company.
Hey Nick. Just wanted to let you know that OSCAR 1.4 is released! That means there is now support for the DreamStation 2, which I have been waiting for for the past 246 days of suffering with no comprehensive data, only the nonsense available from the unit itself and from DreamMapper. Thanks for all your support, and hope to maybe see some analysis of the new version in the future!
Oh, the DreamEraser!
Any idea if this version will work with a new resmed BiPAP. I've been without data for what seems like at least about a year now and I'm still struggling.
Really interesting - am gonna go through my data with Sleep HQ today. Not sure if this is your Easter egg but I love the add in from 16:13
Nice one Mike . The easter egg is here brother - 0:54 . If you look in the right sunglass reflection
Got a new one earlier this year. Hope it stays safe.
Your page here has been a real 'eye-opener'. I have been on a (res-med - air sense 10) C pap for 30 years. I had severe sleep apnea until I started using the c pap machine and I do feel somewhat better but still tired in the morning ( more so lately). Should I go to my sleep doctor for an updated sleep test (which now I didn't trust) or just bump up my c pap machine a point or two or more? and see what happens. I'm kind of afraid to self-diagnose but if the tests aren't correct, not sure which way to go now. Thanks for the great info. I really appreciate it.
Thank you my friend. Glad you enjoyed it. Yes that's certainly a difficult decision and one i can't help you with unforunately. I certainly know what i would do. Here's another video however that might influence your decision making - ruclips.net/video/xfeYfoy-BS8/видео.html Good luck brother
Thank you Nicko!
You opened my eyes!!! I didn't know that was possible for me to monitor and evaluate the quality of my sleep. Indeed I think that having this opportunity will my sleep get better!
Jesus Christ! I'm gobsmacked. I'm getting SleepHQ right now for my Resmed AirSense 10. This is the kind of data I want
I had a CPAP and everything was good at first. I cleaned it once a week as demonstrated in the company videos. My machine got sick there buy making me sick and the company only said "buy another one" I learned to sleep in my recliner which ended my snoring problem.
Looking forward to the O2 ring integration. My ave. O2 from sleep study was 90% and API was 97 events/hr. BIG wake up call. With CPAP on, down to 1 event/hour, but O2 average still 90%, using O2 ring. Checked with Resmed pulse oximeter - median O2, 90%.
Hi Carolyn, thanks for sharing your experience mate
This is awesome. Your work is fantastic thank you! I have an 11 and a mini and I want to sign up. When will you guys be able to do the mini, and can I merge the data for the 11 when at home and mini when on the road?
G'day, thank you! The mini is hard as there's no SD card. All data transfer is done via bluetooth and we'd need a ResMed API of sorts to make it work. The Air11 is working well and i just added wifi to mine with the SleepHQ magic uploader that we're currently beta testing. It's awesome. Cheers
Great tutorials 😎
Glad you like them!
Thanks for another informative vid. Can I ask what is the normal breathing pattern we are born with? My understanding (I was involved with the SIDS foundation) that breathing does change during the night when the brain has enough oxygen it slows and when it needs more it increases. This is achieved by the brain on / off switch. But with SIDS the switch doesn't start again. So what is normal VS not normal. I currently use an AirSense 11 AutoSet and have AHI average around 5
I need to get a card reader so I can use this. This data is amazing!
Best move you can make while on sleep apnea therapy.

You're Awesome Dude!! That's all I have to say :)
You rock! Thanks
Very informative video. My AHI is very low (0 for more than 50% of the nights). However, I have some hypopnea like events associated with RERAs and I think these should not count in the AHI. The RERAs are often associated with mask leaks (full face Amara View) and to make the long story short, if I awake, there are no hypopneas, but there is no sleep either...
Thanks for sharing your experience
One feature that might be nice with this respect then is a split screen mode or overlay mode to compare hours or nights.
G'day mate, yeah that's a very cool idea! I like it I'll add it to our big list of features we're currently developing.
I just signed up for a SleepHQ account have yet to upload any data yet. I have been using a CPAP machine for 15 years and am now very curious as to how my flow rates look. Thanks for the tutorial. Cheers.
Hi Peter, awesome mate! Welcome to the party let me know how you go
Awesome video,any chance you can do a video on how to go to the sleep hq site and drag files and and what files do drag and how ,im not so great with the phone
Sure thing mate, i'll be doing a whole bunch very soon!
Great video! Can you tell us what is the "proper" threshold for breathing reduction in order to "count" the events?
Hi Joseph, that's a great question my friend and I'll give you a pretty detailed answer. If you were to do a ResMed home sleep test they would use the following definition when flagging hypopnea. This is the AASM (American Association Of Sleep Medicine) recommendation - All criteria must be met.
a. The peak signal drop by 30% of the pre-event baseline (pap device flow rate)
b. Duration of 10 seconds or more
c. 3% drop in oxygen from pre-event baseline or the event is associated with arousal (going from sleep to waking).
Now obviously the PAP doesn't have an 02 signal (well some have integrated 02 probes) but even still that info isn't factored into the algorithms. So the PAP just goes off the flow rate.
To be totally honest, the whole AHI thing is a really bad system. What if your breathing drops 29% instead of 30% and you have a 30% drop in your oxygen levels? Or what if you have an 80% drop in flow rate for only 9 seconds? They're trying to standardise diagnosis/treatment for a condition that shouldn't be standardised. Anyway, I'm going to try and fix these broken industry standards. SleepHQ will help. All the best. Nicko
So there home test study is a 30% drop. But, their machines are 50%?. I though you can tinker wiry these settings. I was just diagnosed and waiting for the airsense 10. Chose that instead of the 11 cuz I didn't want all the unnecessary prompts. Wondering if it was a bad choice in model or if I should have asked the Dr about a different manufacturer
I’m just doing a trial with a resmed airsence 10 are these any good .? I really enjoy your videos 😁
Is there a way to go through my data on the Sleep HQ and edit it by adding in a H or CA line for the noticed changes, and Do the RESMED 10 or others machines update on their own?
G'day Andrew, that's a really cool idea mate! I'll chat it over with Adam. We're pretty busy working on machine compatibility right now but in the future we want to provide analysis tools on the platform that will provide a more accurate report. Cheers
Hey been following the channel for a while even though I don't use a cpap. I have tried it on several different occasions and have never been able to get used to it at all. The doctors say I have quite mild apnea, but I have had crazy levels of grogginess for the past 8 years, have not woken up feeling well rested for the same period. Not once. I also sometimes cannot get back to sleep even if I wake up at 3 or 4:00 in the morning. I have something wrong with my central nervous system I think, I had undiagnosed OCD for many many years and a lot of stress and anxiety.
Just wondering if you know of anything else I could try. I've tried a few different apnea machines, I've tried various different settings, I've tried different masks, I don't know what the hell to try anymore. So I gave up a long time ago, but I'm still having pretty shit sleep as you say. I even tried a dental appliance but that just made my jaw hurt. It's very hard to fall asleep and stay asleep with the CPAP changing the pressure in my mouth. My brain thinks that something is trying to suffocate me I think.
Have a look at Vic Veer's video on RUclips. He is an ENT surgeon and has put together a quick simple throat/ tongue exercise plan. Its been helpful for many people and worth a try. I have started it together with my Resmed therapy and have noticed a difference.
OMG! THIS IS IT! I´ve been using my CPAP for a month (Resmed S10) now and i am still so tired feeling like bull**** (not as like when i was not using my CPAP). My doctor changed the pressure many times in this month, from 14 to 12, then to 11 and back to 14 because my AHI goes from 1-2 to 30 depending on the day. 14 is the spot where i maintain the AIH below 5 ALWAYS, but i can´t sleep well because i have only a couple of hours of it thanks to the uncomfotrtness i feel when i wake up wearing my mask and feeling like i am chocking. I´ve been on licence for 2 months now and the doctor said i will be able to get back to work asap because the therapy is going well in general and the only thing that left is me to get used to it.... I´m still feeling pretty bad :/
That's a tricky one mate. When you're just starting out i recommend you focus more on comfort and compliance. Just try and get to a point where you're using it 4+ hours a night. After a couple of months, your breathing will adapt to the pressure and then you can shift your focus to better apnea control. Good luck!
Those large swings could be chin tucking OA clusters, on oscar they look like 1=oa. 1 1 1 11111 111 1 1 1
Nick, do you consider REM SLEEP or good BLOOD OXYGEN a priority? If I don't restrict my rem sleep, my blood oxygen drops several times/night into the 70% range. I wake gasping for breath. If I take a little caffeine before bed, I still sleep well but perhaps not as deep a sleep. My blood oxygen graph is much flatter and I average about 97-98% with O2 scores in the nines. (O2 Ring) My events range 0.9 - 5/hr. I am pretty certain there are no obstructions causing me to stop breathing. I think I hold my breath during dreams. Resmed 10 set on manual CPAP at pressure of 18. No leaks. CPAP opens my sinus and permits me to breathe very well via my nose. Initially, I did not tolerate CPAP but now I love it. Thanks in advance for your answer.
When I switched from my Phillips machine, because of their shite foam, and bought a Resmed machine. I haven’t felt as good since.
