Not recording proper usage
So I just got back from a trip to Norfolk, VA and I took my machine with me. I used it every night for at least 7 hours, but each morning when I woke up it said my usage was actually less than what I used it for. The first night, which I slept great and my AHI was down to 3.0, I slept for over 7 hours, but the usage only showed a tad under 6 hours. The last night I used the machine for right about 7 hours, but the machine showed I used it for less than 6 hours. I traveled from Hawaii to Norfolk and did not mess with the time settings at all. Not really understanding why I was getting incorrect usage hours and wondering if I should believe the AHI numbers if the usage is incorrect.

Anyone else have this issue?

RE: Not recording proper usage
You are from Hawaii (UTC -10:00), and you went to VA (UTC -4:00), that is difference in 6 hours due to timezone differences. It is possible that your machine was putting the time in the next/previous day (switch over is typically 12 Noon).

Your sleepyhead daily report would show the sessions you had and how long they were.

Well gosh! The time change from Hawaii to the east coast must have cancelled out the hours of CPAP use.

I have no idea what happened, but figured, anyone that has been in Hawaii can handle the abuse. Smile

I am thinking it has something to do with the timezone changes.

Yeah Hawaii is beautiful, but I am really looking forward to getting back to CONUS permanently next year.

I haven't downloaded the data to sleepyhead yet, but I got all smiley faces on the machine. I'll check that out.

RE: Not recording proper usage
I'm having the same problem with my Aircurve 10 ASV. Sleepyhead is showing me that the recording is for the day before, and when I hit the stop button when I wake up, after so many hours; even if I get up to pee or not, it says 0:30 on the timer, even if I had it on for over 8 hours. I plan on calling the DME back tomorrow. Might have to have them come mess with it, or switch out my machine. My doctor said she noticed that chunks of my data have been missing.

There have been some issues reported using sleepyhead and the Aircurve 10 ASV. You might try ResScan and see if it sees something different.

RE: Not recording proper usage
I had a similar problem with my new Aircurve 10 Vauto. When I looked at my Sleepyhead data there were blocks of time in which it did not record anything. It was losing blocks of data every night and it was under reporting my usage. I exchanged the first machine and the second one did the same thing.

I believe it is caused by an overzealous compliance algorithm. The machine looks at several parameters to decide if you are really using the machine or not. If the machine is running and it senses you are not really using it, it stops recording data.

In my case, I switched to a full face mask an the problem went away--even though I had a smiley face for low leakage when using the nasal mask.

It's not just Sleepyhead. The machine will log time I spend on it, and then on the last button push of the night, to turn it off, I notice it says 0:30 instead of the full 7-9 hours I had it running.

I also use a FFM; a Simplus. What would cause it to compute that I am not using it, when I am totally using it at compliance? I don't get it.

RE: Not recording proper usage
If you put the machine in Auto-OFF, then it won't make a difference if you think you are still using it. But, at least you won't have to push the button to stop it. Maybe that will prevent you from getting the 0:30 reading.

By the way, watch the screen for a couple minutes and see if 0:30 reduces to 0:29 or 0:28.
