I'll bite: what's a CPAP machine?
It looks like a mini vacuum cleaner and is compact enough to sit
on your bedside table. It's for Sleep Apnoea sufferers.
You wear this tight tight mask, turn it on, and what it does is
regulate the air pressure in your airways so that you don't end up
snoring and the airway doesn't collapse on you.
It can be pretty uncomfortable. If, for some reason, the
air pressure gets turned up automatically, you have to exert quite
a lot of strength just to exhale. Of course, if you manage to
fall asleep, you wouldn't mind all these, but I'm a light sleeper
unless I'm semi-dead (which occurs during the frequent episodes
when I stop breathing, ah harharhar!!) so it won't do.
Haiz...
