Need help deciphering these stats

Post by SleepyRose » Wed Feb 18, 2009 7:50 am

Last nights
OA 3.7
H 3.5
VS 15.2
Large Leak 0.0 0%
Average Leak 52

Night before
OA 208
H 3.7
VS 10.3
Large Leak 2.0 mins, .39%
Average Leak 47

I was at 8.5 the night before and upped it to 9 last night. It looks like I had no leaks (why does it say Av Leak 52?) but my AHI is worse. What can I do to get my AHI down?

The recommended pressure on my sleep study was between 8-10. I wonder if I should up it again?

The average leak for your mask at your pressure is 33.5, Your average leaks were 52 and 47, so you did have some leakage. Last nights AHI was better not worse. You need to keep it where it is for a few nights(I like to give it a week). Making changes too quickly will mess you up. Every change means your body needs to adjust again. If after a few nights your results haven't improved at all, then change your pressure to 9.5 for a few nights. Remember to change only 1 thing at a time.

Leaks and large leaks aren't the same. Large leaks are when the leak rate gets really high.

You can have plenty of leak problems without having a large leak show up.

What do the leak graphs look like? The LED data for the m series leaves tons to be desired. As Goofproof says you got to look at the "dailies" - graphs graphs and graphs.
