Clear airway (central) apnea and alcohol
My CPAP machine is showing variable rates of clear airway apneas, varying over a number of nights.
Interestingly, the rate is much higher after having an Alcohol Free Day! After a couple of standard drinks before dinner, it is usually below 5.0 (and often 1.0 to 2.0), but after an AFD, it is usually above 10 and sometimes over 20.
Can I get a Rx for a good Scotch? Smile
Is anyone aware of this "problem"?

Strange. I'm no expert so hopefully some one who is will voice their opinion. I was told that alcohol can increase the number of AHIs because it relaxes the muscles even more.

Alcohol is a sedative, and sedatives make obstructive apnea worse.

But this is a case of alcohol lowering the number of central apneas.

I suspect that this effect will subside with time.

RE: Clear airway (central) apnea and alcohol
Could also be that other factors that happen on AFDs are contributing. Like stress levels would be higher, etc. If you had a good day and went out drinking with friends, you'd have less stress and sleep better. But if an AFD happens during the middle of the week with a lot of stress, then your sleep would be off.

Interesting hypothesis.

RE: Clear airway (central) apnea and alcohol
The CAs are probably from hyperventilation caused by increased pressure. Alcohol suppresses resperation which in turn could make it less likely that you will hyperventilate. This is just a guess as to what may be happening.

Hyperventilation should go away on its own in time with acclimation to pressure.
