Help Interpreting OSCAR data

Welcome to the board - from the full night it doesn't look like you're using EPR 3 (rather EPR 1).

It's normal for new users to have more central apneas while your body adapts to CPAP so I wouldn't worry too much. I'd recommend the following:

1. Increasing EPR to 3 full time
2. Increasing minimum pressure to 7cmH20 so you can benefit from EPR full time
3. Decreasing your maximum to 14cmH20

Try that a couple of nights and see how it works out for you. I bet a lot of those unmarked hypopneas will smooth out. Do you have any other comorbidities like COPD? What's your nasal hygiene routine look like on a daily basis?

I have high blood pressure and Generalized Anxiety which I treat with CBT and the very occasional xanax (once maybe twice per month).

I'm not sure what you mean by nasal hygiene?  Thank you for your reply!

egglocsta,
I was about to give you the exact same pressure recommendation as gainerfull.
A minimum pressure of 4 will usually cause you to feel,"air-starved".

Considering that you stated that you were awake when some of those CA's occurred, you can just dismiss them. Some are probably Treatment Emergent though and will lessen in time.

The recommendation to use EPR 3 is sound, as it will help with flow limitation, Hypopnea and RERA. Try for a few days and see how you feel, but if you see an increase in Obstructives, you will need to raise the minimum a little. We can reevaluate after a few days.
