OSCAR: numbers on event flags

As long as the machine detects breathing, it records the time it is on. If it is on and blowing to, say, dry out a hose, it won't record anything. It probably counts toward machine hours, though.

There's a lot of times I go to bed then lay there awake for an hour or more. If I realize it has been that long and finally feel myself drift off, I turn off the machine, wait at least 61 seconds, then turn it back on. When I view the data later, I just turn off that wake period and get a more accurate data set.

If you are unable to use it longer than 3 hrs, then sit up during the day with it on while you read, watch tv, whatever. This gets your body and brain used to the sensations of it all.

Thank you for your response.  You confirm my thought:  time on is not necessarily time asleep.

Can actual sleep time be measured? 

It isn't that I can't tolerate the machine longer than 3 hours, it is my chronic insomnia that is the problem!

in case it isn't obvious, the 4 hours doesn't have to be continuous. when I first started it generally took me 18 hours to get 8 hours sleep. now still fragmented but less so as sleep sessions have been getting longer & time between them getting shorter over time.

If we're on the 4 hours for compliance, the 4 hours has to be any time between noon today and noon tomorrow as that's a "day" to the machine. During my compliance, I've had to break my time into segments and it shouldn't be a problem.

Yeah, that's my problem, too.

For me, if I don't remember to turn it off/on or I actually go to sleep (ha), I can tell what time I lay there awake. The pressure line is relatively flat compared to the rest of the night/day. It can have some slight increase but once I am actually asleep, the pressure jumps upward. I also tend to have "sleep junk" central events while laying there. Most likely just simply holding my breath while I roll over or something.

In the screenshot below, you can see not only does the pressure increase, but the flow limitation becomes active and the flow rate becomes...more bumpy? Jagged? Yeah, I'll go with that.

Thank you for pointing that out.  Not being the sharpest knife in the drawer, I hadn't realized that, which is why I was keeping the mask on while I was awake and reading until I had got more than the 4 hours in...

Thank you for your explanation:  so, going on what sheepless has just said, I could take a nap in the afternoon using the machine for , say 2 hours, then  the hours in the night, say 3, would be added on, making 5 and therefore in compliance? 

How then would that look in OSCAR, I wonder? Thinking-about

It would show as two sets of graphs with a white gap in the middle.


But a note of caution only import into Oscar when you getup in the morning and don’t intend to sleep anymore do not import into Oscar after you afternoon nap otherwise your second nighttime session will not import without clearing the day first

I think that would be fine. See jaswilliams notes to see OSCAR charts accurately if you have multiple sleep sessions.
