I use SleepyHead and just figured out how to enlarge the flow rate graph in the daily screen and use the arrow key to scroll through the entire night. I notice that I'm having a lot of hypopneas that last less than 10 seconds so they are not being recorded as events. Are these short episodes enough to cause my symptoms?
I also notice that around 4am every morning the hills in the flow rate graph start looking flat instead of rounded and my pressure goes up to and stays at max pressure which is 12.
I'm going to turn the max pressure up. I've had it at 13 before but wake up feeling bad like my lungs are overinflated. Is it possible to get used to the higher pressure if I take it really slow, like 0.2 cm increase (12.2) for a week, then another 0.2 cm increase (12.4) for a week, etc until I get it high enough that the peaks stay rounded and I stop reaching and staying at the max pressure for extended periods? Or would it be better to just leave it at 12 cm H2O?
I also have a pulse oximeter. Last night my basal O2 was 97% and my low O2 was 91%. It only dropped down to 91% once for a very brief period and it dropped down to 92% twice for very brief periods. Other than that it was 96-98% all night.
