It opposite for copd. Co2 also dilates vessels....especially in the brain.

Literally can’t do this so embarrassing !

Dumb example. My oxymeter shows oxygend down after few seconds of holding breath. Don't trust all what's online

C02 buildup. Causes blood toxicity. This makes you WANT to breath 🫁.

Is that man's pulse in metric or is he freaking out?

This is why high nitrogen environments are very dangerous because your body doesn't have the same result of breathing in nitrogen it will aptly take it in but if you're exposed to too high of CO2 levels you'll definitely notice

Broooooo you just solved a whole life for me in less than 90 seconds 😂 but wondering, how can you start practicing this correct tongue posture?

SMH 🤦

u brether oksigen..Now I Tell Where Oksigen Go..Exit Fart..Hahahaha....No No. Oksigen U brether Go to All part in Body Use The Oksigen..Not U use Oksigen U take Oksigen Give to Ur Part Body...U hold brether Ur Face Like Ghost No Color.Because u part cannot do Work..Slowly All Stop 1 Part And Part in Body..

What did the winner did this year? Congratulations

Carbonic acid, builds from CO2 in blood, causes us to feel panicked.

Excellent demonstration!

I also saw a video where a girl had to get something out behind her teeth because her tongue would push the teeth causing her teeth to flare out. Then I realised that's what my tongue does as well and I have bad teeth arrangement in general so I didn't realise that the reason why my front teeth are sticking out is because of my tongue. Going forward I'll pay more attention to how I position my tongue.

Very interesting, and thanks!

What about the flashing red light, sometimes, in the left-bottom? Thanks for the video!

The oxygen advantage by Patrick Mc Keown

Youre becoming a premature CO2 retainer, your body will have to start to retain more HCO3 (base) to balance out the constant CO2 (acid) increase, in order to keep blood pH between 7.35-7.45

Breathing with nose takes longer, also doesn't create turbulent flow of air, physics of the air going in through the nos and to the trachea with less cornering, with laminar flow of air making it fill up the lungs with more volume of air than mouth breathing.

but if u exhale all the co2 you still need to breathe.. meaning ur wrong

I have done it and you have 60 seconds of air in you. then it starts going down. 😂

First of all the oximeter always showd a delay, and the "respiratory reflex" is actually measured by different types of receptors, some of them being related to low CO2 preassure and other ones for O2 being it a complementary response

Can this be used if you’ve been over breathing for about a month with severe air hunger?

Lovely video. Signed up this year.

Okay, so what if you take a series of short shallow breaths followed by BIG exhales to reduce the active amount of oxygen and co2 in your body, then held your breath? Would you be able to hold your breath for longer since there is less CO2 build-up?

It's a carbon dioxide build up that causes you to breathe so that you can expel the toxins

Its called hypoxic drive if you want to educate yourself.

I noticed when I was younger that when I hold my breath underwater and slowly let out the air in my lungs, I didnt feel the need to come up to quickly. Now i know why. As long as google supports this theory once I look it up after this 😂

As a competitive swimmer we were taught this. This is why it’s a bad idea to hyperventilate while doing underwater challenges.

Fun fact. The body has no mechanism to detect low oxygen. This is how people expire in low oxygen environments

Actually the two basic triggering mechanism for breathing is Co2 buildup, or Ph drop.O2 also can trigger it, but just a little tidal volumen increase, it almost nothing compared to Co2/Ph. It will increase the rate of Breathing/minute and/or the amount air you inhale/exhale. Thats why patients with build up keton (Diabetic Ketoacidosis) lower the ph of the blood and then comes the typical "Kussmaul" breathing. Your body try to normalize the Ph by breathing out Co2 witch can cause spasm, and its very bad for overall vein/artery system and also for your brain. You needs a certain amount of co2. COPD patients usually fine with 60-90mmgh Co2 level (witch is very high). Your body can get used to it. But its require many many jears. They have normal ph with high co2. Common compenstion mechanism with Hco3.

Hi David! Hope all is well with you! :=) I discovered channel through one of my friends recommended your channel. He said that your content is very good. My question to you is if one has rib flare, where to start, what direction to take? what is your recommendation on rib flare?

i have sleep apneau should i train co2 tolerance.Thank you..

Who cares? I breathe to live. Don’t really get why sone pseudoscience man thinks this makes him important. You will breathe regardless of why.

Now lets do the same thing... but in a pure nitrogen environment.. Your body doesnt know youre not breathing oxygen.. night night

according to your experiment people who hold their breaths longer under water after inhaling pure oxygen are lying. 🤣 Bro there is a whole category of sport based on this and you are saying scientists are lying too in a way . 🤣

When oxygen goes down, CO2 goes up. So yeah it's still oxygen.

do the same thing after you have exhaled completely.

Thank you for this advice, ever since I tried this technique I've seen such great improvement in my breathing ❤️

There is also a 6-10 second delay in these devices.

O2 sat meters display a recent average, not the live level.

When saturation down mean o² in blood vessel move to the organ . I can make saturation down from 99 to 0 .

This is why rebreathers in scuba are so dangerous. You can turn the scrubbers on and forget to turn on the oxygen and you'll die in complete comfort as your CO2 level never rises and O2 plummets

Do an experiment where someone can only breathe out (to remove the co2) and watch if they need to breathe. If this does happen my prediction is co2 plays a role in all of this but even though you have very low co2 level you would still want to breathe (choking sensation not like casually breathing)

Gas exchange important. But who cares weather your brain measures the input or output hehe

There was talk in EMS about switching to c02 monitors instead of the pulse-ox he use inbthis demo.

That "noise" should come from the suctioning of the tongue on the palate. Jack, your noise is coming from the tongue flapping on the floor of your mouth. Try again for us!

CO2 diffuses across the BBB into the CSF where it forms into carbonic acid, which then dissociates into H+ and bicarb. This increased H+ stimulates chemoreceptors near the dorsal respiratory group to increase minute ventilation.

If I hold my breathe o2 goes down

This is why dead air zones are so dangerous. Gasses can build up and you can still breathe and not feel anything. The suddenly youre dead. Canary in a coal mine and all that. The birds would die first which was your warning to gtfo. It’s also why nitrogen chambers are considered the most humane form of execution. Our atmosphere is 70% nitrogen. We’ve been breathing it our entire lives. It’s harmless and doesn’t have a taste or smell. You can breathe, expel CO2, and just go to sleep and you wouldn’t feel anything. Hypoxia sets in pretty fast and gives you a giddy light headed feeling. Your brain function plummets and while you may be scared at first you’ll be so loopy you’d forget what’s even happening. Then youre gone.

That is real teaching not go home do 14 pages of homework, and memorize from page 10 to 29, i hate my country
