A little Help from my friends please. ..interpreting data.

Last night was the opposite of the night before where I had some very good numbers...AHI 4.5 and AI 0.5. Last night the numbers were AHI 8.2 and AI 2.6.

Now here is the kicker. When I checked out the results on the computer all of my AI's occurred in a 15 minute span from 2:00 to 2:15....only two minor ones the rest of the night. There was 12 AI in that 15 minute span and they were long...from 38-56 seconds. Looking at the leak graph it looked like the rocky mountains but the leak rate never went above 0.2 L/s. It oscillated between zero and that number...well below the 0.4 level. The really odd graph was the pressure graph. I was running on Cpap start of 13 with a ramp of 20 minutes and then up to a straight cpap of 13.8. During the 15 minute period that I had all these AI, the pressure graph spiked down to 10 or below about every event. What the hell is that about? The snore graph showed definite snoring going on during this 15 minute period....they too looked like the rocky mountains...but barely up to the loud snore level.

Sounds like you kinked up your hose while you were asleep. How do you route your hose?

I started out on my side and it was just laying by me on the edge of the bed.

I would have thought if I laid on the hose I would have lost all pressure. These were like straight lines straight down and then back up...similar to what you would see when you were on apap and the machine was spiking up to deal with events...only this was spiking down.
