Question Regarding Minimum Pressure and APAP
#1
Question Regarding Minimum Pressure and APAP
How exactly does an APAP determine the correct pressure for your needs? I have always thought that the pressure would go to the best amount depending on what you require. This does not seem to be the case with me. Normally I have my ResMed Airsense10 set at 11-14 (cmH2O) and the 95% usually averages out ~ 11.5 - 12. The last couple of nights I reduced to 10-14 and the 95% averaged out to 10.88 and 10.94 respectively. I'm wondering why the machine doesn't level out at the same value regardless of the minimum set point?

Anyway the reason why I have been playing around with the pressure is that I'm trying to improve my mask leak rate. My theory was that my higher pressure of 11 may have been too high and maybe pushing my P10 nasal pillows out too much causing leaks. It doesn't look like it worked. I'm also thinking that I may have snored or gasped for air that woke me up last night even though my Oscar data didn't show any snoring.

I have attached a screen shot from a 11-14 session and a 10-14 session. Am I over reacting about my leak rate? Is it ok as long as I stay under the 24 L/min limit? I have been trying different masks lately with no significant improvement.  The most recent new masks were the P30i and the N30i. I seem to have very weird dreams and night wakeups with these masks.

Thanks in advance!
