Interesting night. I need to write down data from the Airsense 10 window when I go to the bathroom. As I recall, I got up at elapsed time of something like 4.4 hours.
There is a gap in pressure and flow between 22:40 approximately and 00.12 approximately. I was asleep. You mentioned that might be a time when the mask was dislodged. I sleep on my back almost all the time and wake up on my back so something happened. Any more ideas? Should I tighten the mask straps? I must have been breathing during that time.
Or maybe I was sleep walking and got up and went to the bathroom. Going to the bathroom requires shutting down the CPAP machine and disconnecting the hose at the same time because of the automatic start.
I have included another graph of different variables.
After I wake up for the major bathroom break, I sometimes do breathing exercises to relax and go back to sleep. I know that CO2 is the gas that regulates breathing. Some of the authors I read say that there is a need to increase CO2 for health reasons. One exercise is breathing in a paper bag. Last night I used a modified 4 6 8 routine. Not sure about the magic numbers and didn't follow faithfully. But the strategy is to breath in quickly, 4, hold breath for a longer time, 6, and then exhale, 8, to maximize the CO2.
Does this explain the graphs for these variables? Title volume, Insp. time, Exp. time?
Here is how I can tell if I went to the bathroom in that first 15 minute break. I may have have mentioned that I have an artificial unitary sphincter to control leakage as a result of prostate cancer removal surgery. The nylon device is implanted. There is a bulb in my scrotum that when squeezed sends air pressure to open up the sphincter on the urethrae. It takes two hands to operate the device. Left hand to hold the top tube out of the bulb to stabilize the device and the right hand to squeeze the bulb. I have to stand up because if I sit down there is not enough gravity to empty my bladder and I leak on my PJs. I made an artificial urinal by cutting out a section of a 1 gallon plastic water jug. I use my pinkie (left smallest finger) on the left side of my hand, putting it in the handle of the jug, and the rest of the fingers on the left hand to hold the top tube, and then using the right hand to squeeze the bulb and aim. I can empty the the jug each time. So when I get up after say 5 hours, I can tell if I got up earlier and went to the bathroom earlier.
Given all the stuff around my head: cushion, frame and cervical collar, it might be sleepwalking.
