Regular CPAP or ASV
#1
Regular CPAP or ASV
I started feeling tired again even though my CPAP data was showing the sleep apnea was under control.

I convinced my doctor to let me try ASV and felt that I was much better rested after using the ASV compared to CPAP.

I have attached some data for 1 night each of ASV and CPAP. Does the data explain why I would be feeling so much better on the ASV or should the CPAP be sufficient?

RE: Regular CPAP or ASV
Going just by the data I’m seeing here, the ASV sample shows reduced Clear Airway events vs the CPAP. That just means that the ASV is doing what it’s intended to do.

Some possible problems with this scenario you’ve presented here in attempts to answer your question:

This is a very small sample size for both machines. It’s better to see multiple days to view trends. There’s lots of variables involved, much more than 2 separate machines. Realistically even if the machine, settings, mask, etc. were left the same, no 2 nights can give identical results data, but there will be trends and patterns that should be recognizable.

How were things on the CPAP? You’re stating that you were getting tired again. What else might have changed? How long were you using the CPAP before deciding to switch machines? How many Clear Airway events were showing in the recent past? How new is the CPAP?

Certainly a higher level machine should be better but only if it’s truly needed should it be considered. Realistically you should consider all optimizations possible before entertaining a different machine.

If it turns out that you need the ASV, you’ll certainly get great results. The above things I’ve brought out aren’t intended to persuade you against the ASV if you need it.

RE: Regular CPAP or ASV
On your AutoSet turn on your "Pressure" on tour Pressure chart. SleepyHead has a bug that continually turns it off. It appears that you are using EPR on the AutoSet and when trying to reduce Central Apneas that is not always a good thing. You also want to show Flow Limits. Flow Limits can bring to light issues that don't show in the AHI readings.

Set your AutoSet to Min pressure = 5 and Max pressure = 5 and let us know what your EPR is set at, my guess in 1. then try it and post results. The next change would be to increase EPR with adjusting your other settings to emulate the PS you are using on the ASV.
