AirSense11 not catching CAs - jake.love - 11-12-2024
Hi all,
I woke up this morning feeling extremely lathargic but with a great stats on OSCAR, comparable to yesterday morning when I felt much more rested. I did a deep dive on my flow rate graph and began noticing multiple instances where I think I'm having CAs but they are not being logged on the software. Can anyone validate this or have any suggestions? Thanks, screenshots included.
Edit: So far I've identified 10 to 12 instances of this.

A Clear Airway event is defined as a cessation in breathing for at least 10 seconds. The Cpap machines won't flag an event if under 10 seconds.
"CA Events are flagged by many CPAP and bilevel PAP machines, and are apnea events of at least 10-seconds duration and determined to be of an open airway type."

Even if your AutoSet flags it as CA/Central Apnea/Clear Airway, it can't treat these. You can only attempt to avoid them, of which it appears they're of an amount that needs no treatment requiring adjustment. If you did attempt to address the CA, it'll likely negatively affect all the other events, which are currently controlled, according to this chart. Actions to control CA are on one side of the treatment teeter-totter, all the other events are on the opposing end.

That type of breath happens when we hold our breath to turn over in bed or pull up the blanket - any time we stop breathing while in bed. If it is less than 10 seconds it is not recorded as apnea.
