Sleep apnea?Until I wake up gasping for air
Sleep apnea?
I have mild pulmonary Edema from my heart condition. Sometimes wake up feeling like I’m drowning. Not pleasant, but the diuretics keep it under control mostly.Now and again yes, more frequent when stressed and dones't bother me otherwise.
2 minutes 20-ish is my record from a few years ago... tried it again relatively recently and managed over 2 minutes ago.
Biggest factors here are lung/O2 holding capacity and ability to manage the gasp reflex (or whatever it's called): tests with idiots and curare (muscle relaxant) show that - in the average person running at full saturation - blood O2 levels don't get dangerous until around 5 minutes (never managed to square this with my [limited] first aid training)... the test subject who was describing this at the time explained the reason they cut at 5 minutes was because the supervisors got panicky.
So what it - ultimately - comes down to is suppression of the gasp reflex in the first instance... you'll see videos of training divers starting to hiccup underwater as their bodies try to force intake of breath.
I believe that was only accomplished on pure oxygen. In terms of what can be achieved by an expert randomly taking a deep breath of normal air, I'd expect somewhere lower than 20 minutes.World record is about 20 minutes by a freediver so it's possible but needs a lot of training even by the fittest.
Around 11 minutes.I believe that was only accomplished on pure oxygen. In terms of what can be achieved by an expert randomly taking a deep breath of normal air, I'd expect somewhere lower than 20 minutes.
I find the bleeding eyes an issue before breathing becomes one.about 5 minutes after the wife has farted
