New CPAP Owner Questions

I again suggest you lower EPR it will bring down your centrals and of course less time in apnea.

Reduce your EPR to 1, if needed we will adjust from there.  That should lower your CA events.

You are among the (un)lucky individuals that may be suffering from Treatment Emergent Central Apnea.  This often occurs with new CPAP users as you CPAP helps you breathe more efficiently, including the flushing of CO2 from your system.  Our main drive to breathe is having enough CO2 in our system to require removal. When CO2 levels drop below your apneic threshold a central apnea occurs until your CO2 builds up while you are not breathing.  This occurs gradually in a waxing and waning repetitive pattern.

To confirm provide a 10 minute zoomed view of your CA events and
Post your sleep studies, redacted, especially your initial diagnostic study.

I finally got to the EPR of 1.  The CA events did not drop noticeably while hypopnea went up noticeably.  Large leak went up from near zero probably do to my mouth popping open and exhausting air.  Are there any recommendations?  Could I just need more time?  It has been 29 days.

2 points first central are very inconsistent meaning one day they are higher one day lower. I would not take one day as a trend.

2nd the increase of H events was due to positional apnea. That is caused by chin dropping to your Sternum usually when your pillow is to high or back sleeping. No settings on the machine causes it or can help it. The only way is not to sleep in that position. Your earlier charts did NOT show this so think about what changed in your sleeping position.
