I feel like maybe one of the causes of apparently such widespread sleep apnea is how most people, as far as I gather, sleep with their windows closed. This is deeply unnatural—we evolved to sleep more or less outside, or at least in a shelter with a steady airflow—so of COURSE sleeping in an unventilated box with stale, stagnant air is going to result in not getting enough air while sleeping. A CPAP machine is basically doing the same thing. This is pure speculation, so I’m curious if anyone else has any perspective on this.

Hmm no the oxygen level is definitely not a problem in most cases, especially considering a sleeping person uses even less of it.

Also a CPAP doesn't increase the amount of oxygen. It just increases the air pressure a bit to keep the airways from collapsing.

This is indeed pure speculation and not how a CPAP works or even sound in thesis.

There is not an oxygen supply problem in a room even if it isn’t actively being ventilated. If there was, you’d have bigger problems. Also plenty of people do have some form of ventilation or air circulation in their homes.

Unless you’re sleeping in a tiny cramped space that is almost fully sealed, this is not an issue.

Sleep apnea and its treatment has nothing to do with whatever work of fiction you’ve invented here.
