Hi, Everyone, I started 2 weeks ago with Resmed AirSense 11. I set it to APAP mode with pressure range 4-10 (sleep study recommended range). I noticed that when I wakeup in the morning (or at night) pressure is always 10 (or very close, like 9.9). It was suspicious to me that machine always operates at the upper range, so, I decided to use it during the day, while working. After 30 mins of use, when I was sitting in front of my computer, pressure jumped from 4 to 7, after that to 7.7, dropped to 6.5 and was fluctuating in that range. Why is this happening? I was not sleeping at the moment and definitely did not have any AHI being awake during the day. Is this machine malfunction?

Thank You!
