[Diagnosis] how to tell if my ca apneas are positional

[Scimorelli]

I noticed on Oscar that most of my apneas are CA or central apneas.  Reading through some posts I found that they may be positional.  What do I look for in oscar to determine if it positional.

You would see a section of events along the timeline that are clustered, one after the other.

Attach an OSCAR chart and let's see what you're facing.

PS Positional Apnea may or may not be showing CA flags. Positional Apnea pattern should most always include some Obstructive and possibly Hypopnea.

What did your detailed PSG sleep study report about Central Apnea?

here is last nights oscar.  I will ask Dr for sleep study results

Take a look at your OSCAR in that left panel. See how it cuts some settings off there at the bottom. Can you scroll up and find Trigger. What's it set at?

Go into the clinical menu, find the Trigger setting and set it to High unless it's there already. In that case go to Trigger very high.

You're on a VAuto, which has a Trigger setting, which may be edited to assist with the CA, as I started to say above.

Also you may want to edit EPAP 4 to maybe 6 or 7 to get you a bit more base air.

trigger was set to high, I set it to very high last night but it felt weird so I lowered it back to high about 8pm.  There is also a cycle setting where I made the same change to very high which I lowered back to high.  Maybe it was cycle that made it feel weird.   For tonight I will raise the epap to 7 and see if it gives me aerophagia which is why I had to switch to bipap from cpap.  Also I will raise trigger to very high but keep cycle to high. What about TI range (currently set to .3s-2.0) and PS (set to 3.0)?

Rarely do you ever change the Cycle setting.

Correct. Cycle Medium will probably be OK for you. For me, nah I had to try changing mine because I've got a complex sort of thing. Complex Apnea and COPD, and VAuto not cutting it here.

Unless you have a high level, predominant Central Apnea on the test, this VAuto will be just fine.
