Please help fix the sleep amount counter

I have a Dreamstation APAP.
My sleep schedule is crazy sometimes and at one point I slept at odd hours for different amounts of time.
I think this confused the device because now the counter for the hours slept is all out of whack
For example I might sleep 9 hours but it says 3.5 when I wake up.

Is there a way to fix this, but not affect the other data, records, and settings? In other words, can I keep everything the same but just reset the sleep hours counter?

Thank you

This is a copy of what I answered another (?) poster yesterday who had essentially the same question -


"I'll guess you tried to read results after noon, and that's the time (noon to noon) machines consider a day (or night) to be, so you have to read things prior to noon to get full results."

There's nothing you can do with the Respironics machine to alter when or what it reports in terms of hours of sleep.
The noon thing that Julie mentioned doesn't apply to Respironics machine...it's a ResMed machine thing.
The "noon" on the Respironics machine is noon GMT time and not your local time and the way the machine shows the on screen usage is more on the most recent session than the time you are looking at the data.

The on screen usage for a full day is based on a 24 hour period from noon to noon GMT time. People that have crazy sleep schedules are going to get some weird looking usage reports and there's not much you can do about it on the machine itself.
Eventually it all works out in the end with X amount of hours of usage within a 24 hour period.

Now if you were to use the SleepyHead software there is a feature in the software that will allow adjustment for the people who end up sleeping past the noon GMT time so that the reports don't looks so fragmented.

It's adjustable using the split day settings.

Not in my experience. I have a Respironics DreamStation and it uses LOCAL NOON time as the cutoff time.

Now that we changed the clocks I am seeing 11 to 11 instead of noon to noon on the Dreamstation.

And where are you getting the numbers from?
The LCD screen or software?
How does it know local time for you? The time zone adjustment thing??? That's not clock adjustment...you can't change the clock.
The Time Zone adjustment thing just makes it so that the machine's noon is GMT noon.

All Respironics machines use GMT noon time as the starting point for the 24 hour reporting period and not local time. They don't have a clock that can be set by the patient to their locality except for the time zone setting which is just the offset from GMT for things.
There is an internal clock and battery not accessible to the patient.

The OP I think is sleeping during the noon GMT, per the machine, so the reports are broken and they don't like it but there's not much we can do about it.
There has to be a break for the new session sometime.
Now ResMed machines we can fiddle with the clock for those that are day sleepers but we can't fiddle with the clock on Respironics machines.

I don't know if fiddling with the Time Zone on the DreamStation would give the OP what they want.
The new session time reporting period still starts at noon GMT time but using the time zone adjustment thing they might be able to fool the machine into thinking it's noon GMT time when they aren't sleeping.

Maybe I worded my comment incorrectly. On one of my insomnia days I woke up shortly after 11 AM and the Dreamstation APAP LCD time read that I had used the machine for 0.1 hours when it should have read much more. It must have cut off the session at 11:00 I am assuming, since sleepyhead had it correctly recorded as a longer session.

As you said Pugsy it is GMT noon, which has not changed. But could the DME have somehow programmed some kind of offset into the machine in July when I got it? Noon GMT is either 4 or 5 hours ahead of eastern daylight saving / standard time, right? So it should split the day at either 7 or 8 AM?

What am I missing?

Just missing the time zone adjustment thing. These machine's don't have a clue about Daylight Savings Time so with the recent change your time changed but the machine's time didn't andthe machine doesn't know it needs to do anything about it.
Is there a setting for DST in the time zone thing or is it just a time zone adjustment that is available to you? I haven't ever seen a DreamStation so I don't know what is offered other than a Time Zone adjustment. We used to have a similar feature on the System One machines but it was only on a few and they abandoned it for some reason. My System One never had it but it was mentioned in the manuals.

I don't know which designations for time zone are used by Respironics,
but my phone uses both CST (central STANDARD) and CDT (central DAYLIGHT) time,
to be manually set for when appropriate.
Odd for Respironics to allow for time zones--but not daylight saving.
And they are an American (aren't they?) company! . . . SMH.

Best just to ignore the front of the machine display, and look at the data with sleepyhead.

Thanks everyone for the replies
Since I'm not interested in dealing with software or other stuff, it sounds like I'm out of luck
But I guess it's good that the data is per 24 hr period so it works out in the end
It must have been like some of you said, that I slept past whatever cutoff point the device had. I think some of those days were one where I slept in pretty late.
Thanks again

If at some point in the future it still bugs you too much and you really want to do something about it and you are thinking of getting a spare machine you might look at the ResMed equivalent of your machine because the ResMed machines have a clock you can set so that the Noon reset time on the machine can be altered so that sessions aren't broken up if you sleep past the reset time.
We have a lot of ResMed users who work nights and sleep days and they just change the clock on the machine so the sessions don't get split.
