The principle behind a CPAP is not air delivery. It provides an "air splint" that holds the airway open. When the airway collapses (or in my case becomes clogged) you stop breathing. It may take a bit for your brain to understand that this is happening. When it does it send a jot of adrenaline to your heart to jump start things. This is the culmination of the apnea event. That is why this so often gets diagnosed as an anxiety attack, is that you wake up suddenly with your heart racing wildly, often perspiring as well. Very similar to an acute anxiety attack.

So adding 02 to a patient does not deal with apnea. Monitoring does not help, as your brain gets it that you are not breathing for 20-30 seconds or even longer, and it takes over in a drastic way. You are monitored in a sleep study, but they don't come in and wake yo up every time you have an apnea event. some of them are not the big whammy event. Like I said in my study it showed I was have dozens of them an hour. So monitoring is of no help.

In obese America, where there are far too many fat necks, apnea is out of control as the air way can collapse as a result of all that tissue . It can also be the tongue falling back into the throat some, which is a positional thing in some people.

But CPAPS force air into your airways to keep them open under pressure, not to provide you air to breathe.
