Using the math to back into it, you must have used the machine 9.6 hours. Subtracting that problematic period (cluster of events), you used it 9.1 hours and had 35 (64 - 29) events. So for those 9.1 hours, your AHI was 3.6 - not too bad, but could still use improvement.Comfortably Numb wrote:I had events throughout the night, but there was a large cluster immediately preceding the worst period of AHI I've ever had in therapy. Between 1:15 a.m. and 1:45 a.m., I had a 29 events out of a total of 64 for the entire night. Between 1:40 a.m. and 2:15 a.m. my AHI was flat lined at 21 and then it began to recede. Not sure this is what you need.This is not a complete answer. I am trying to understand whether that 40 minutes wrecked your statistic for the night while the rest of the night was good.
During that half-hour cluster, what did the leak line look like?
BTW, many of us set the maximum pressure to 20. That gives the machine room to work when our bodies need more pressure, and the machine will not raise the pressure unless it senses the need.
Most of the regulars here don't pay much attention to the AHI line. I never turn it on in my SH charts. It's an index that requires interpretation - not easy to discuss. Best to just look at what events are occurring, at what time and what the leak line looks like.my AHI was flat lined at 21
