Remstar "average therapy hours" question

[emmettdigger]

I just switched to a new machine - the REMstar Auto and because it's new, that insurance business applies - have to use it more than 4 nights. I usually sleep about 6 1/2 hours/night during the week but on weekends, I tend to sleep up to 10 hours. Last night, I slept from 12:30-10 a.m. and instead of my average going up it went down! I can't figure out how adding 10 hours of sleep made my average decrease from 6.5 to 6.13/night. Any thoughts? Also - is there a way to tell how many hours I sleep every night instead of the average? There are nights I fall asleep without putting my mask on and that screws up my average.

Thanks!

The onscreen data doesn't make full adjustments to its numbers until noon GMT time.
The longer we use a machine the smaller the changes you will see on the LCD screen even with a substantial change during one night.
Check out my signature for links for software and you can see for sure what is going to be reported as far as hours of use.
That SD card is what is used for compliance requirements and not a number off the LCD screen.

I am assuming you have a new PR System One machine. If not...let me know and we discuss what is needed for the older models.

As Pugsy says, the machine updates the LCD data at noon GMT time---regardless of when that is local time.

Here in the Eastern Time Zone of the US, noon GMT = 8:00 AM during Daylight Savings Time and noon GMT = 7:00 when we're not on Daylight Savings Time. You are in Portland, OR on Pacific Daylight time right now and you are three hours behind Eastern Time. That means noon GMT = 5:00 AM right now. And noon GMT = 4:00 AM once we go off Daylight time in the fall. And that means all the data recorded after 5:00 AM local lime will wind up not being used for today's LCD display. It will show up in the figures for the next day's LCD figures.

So since you are located in Pacific Time Zone, all the sleep after 5:00 AM goes into the LCD figures on the day after the current one. You slept from 12:30 to 10:00 this morning. But the last five hours of that sleep session won't factor into the LCD data until tomorrow. For today's LCD reading only the four and half hours of sleep between 12:30 and 5:00 AM was used in the computations.

Also as Pugsy says, once you've got a full set of data on the machine, there's remarkably little movement in those 7-day and 30-day averages. I've got a blog entry that explains why those 7-day and 30-day averages are so resistant to change
