I have found myself needing to use CPAP for a few months and be "in compliance" which is defined in my case as a minimum of 4 hours per night 80% of the time. I have a Phillips Respironics Dreamstation and was set up by the very helpful sleep specialist with the app which then auto reports my times.
I have used it daily (nightly whatever) for the entire time I have had it and have kept fastidious time records via both a 4 hour count down timer as well as the time shown on the machine but have found that the app for some reason the app tends to stop at somewhere around 3.5 hours where it generally stays till I run up at least 4.5 to 5 hours of time when it will then jump forward to more or less the correct time. This is a major annoyance since I was not following the app early on and I have 4 nights that show 3.5 hours of use. Not enough to cause compliance issues but enough to screw me out of spending a weekend out on my boat.

I work 12 hour shifts and CPAP compliance it a severe burden on my work days. Basically once you count commute time, cross over time with my colleagues etc, I have basically 9 hours at home between needing to get back to work. Sleeping with this thing is a complete non-starter. I will not bore you with the details, I am sure you have heard them all before. That means that I am stuck either dealing with wearing this thing as I am working on small projects in my shop or while I am working on my computer. I do not have cushy chairs, I don't own a tv, and I am not generally inclined to lay around. That means being stuck playing huff and puff instead of eating dinner, instead of drinking water, instead of playing with my dog but most importantly instead of sleeping. The extra hour or so to deal with the app being silly is tolerable on my days off, but on my work days I am not dealing with 3 - 3 1/2 hours of sleep max and cutting an extra hour out of that is a real burden.
Has anyone else seen this issue and/or know of a fix for it?
Short term, I uninstalled the app and have been taking a picture of the screen showing the 4.0 hours therapy time each night before I go to bed in the event that there is any issues with the data saved on the card.
