CA is short for "central apnea" or "clear airway apnea" The machine doesn't know if you're awake or asleep.

Awake events seen in sleep lab test are discarded. The machine cannot be sure whether you're awake or asleep when scoring such events

What is the diagnoses and titration test

Welcome to the forum and good luck

Clear Airway is part of AHI number.

AHI = AI + HI = number of events per hour (obstructive + central + unknown + hypopnea)

Total AI = number of events per hour (obstructive + central + unknown)

AHI - AI = Hypopnea Index = number of hypopnea per hours

No it means "Clear Airway" and it also means that you stopped breathing for at least 10 seconds while your airway was open, not blocked. Many if not most such events are "Central" apneas where your brain forgets to breath for awhile. But the machine can't actually tell that for sure. You need electrodes on your head to detect that.

Hi Dee digits, welcome to Apnea Board!

Our Wiki has a List of Acronyms and a Glosary of Terms.

Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.

Thanks everyone for you replies to my question. I underwent the second sleep study the night of the 14th. Sleep tech started me out at a 4 and had to increase that higher sometime later.

I turned off all comfort features and just ran straight air. Increased pressure until I felt better in the morning.
This was on an older, non-smart machine. See how it goes with my new AirSense 10 Elite.
