Bathroom visit and smartcard

hecate · Post by **hecate** » Sat Mar 04, 2006 2:03 pm

Hi,

Last night, or more properly this morning, I got up to go to the bathroom and to clear my sinuses after about 7 hours sleep. I went back to bed and slept another 4 hours (it is the weekend and I have a sleep debt to catch up on), but this does not seem to be recorded on my smart card. Neither Encore Pro or MyEncore picked up this second round of sleeping. Is this normal?

Thanks
Liz

As described, your experience of not having the time after a brief break recorded on the SmartCard isn't the experience seen here with my REMStar AUTO CPAP w/CFLEX.

In my case, the machine shows a small vertical Black line across the green compliance bar and then the rest of the time in the sack shows up in an appended green bar.

It would be interesting to know how long your break is and what the Help files for the software say about how long a break can cover before a new day starts to be recorded.

How many times has this happened?

The way I understand their specs, Respironics machines are limited to recording 3 usage sessions a day;

http://remstar.respironics.com/specs.htm

One nap
One tuning off the machine after 30 minutes because the mask doesn't sit will
One bathroom trip
No data after that.....

Not so good for those who watn recording of the number of time they get up.

When I get up in the middle of the night for a bathroom visit I don't turn the machine off, I just hit the ramp button. When I return I put the mask back on and continue.
I wonder if this screws up my mask leakage statistics?

Liz,

That doesn't sound normal to me (unless the card got pulled out).

I'm thinking from my experience that if it's been off for over an hour, it'll start a new "session" (chart). On the first day that I set up mine, I had about 5 periods of sleep time for which it created several different charts, but as far as the "sleep time", it kept all of that for tha daily sleep time for that day (which shows up in a green time-line bar) in Encore Pro. My sleep time for that day started early that Saturday afternoon and covered through the next Sunday morning and showed a total of 10 hours and 43 minutes.
But, as for NOT recording a sleep session, that's not normal.

Doug,

Better turn your machine off before you take off your mask to go to the bathroom for a "pit stop". It'll probably show up as "large leaks" in your sleep statistics.

Best wishes,

Den

Downloaded todays data and along with it came my second sleep for yesterday. Glad I didn't lose it, but not sure why it happened that way. It recorded the time correctly an everything.

Thanks for your help. I have another question on my results, but i'll ask in another thread.

Hello ozij,

My data recording experience was a little different than what you show, so I went looking at the spec page referenced in your post and found our machines are a little different, but not by that much.

On my machine's page:
REMstar® Auto M Series

The data storage capacity section shows this information:

Code: Select all

Data Storage Capacity:
   Display: 7 and 30 day averages
   SmartCard: 6 months at 3 usage sessions per day, 7 days in-depth analysis

When I went looking at my compliance history graphed bars they show interruptions in the daily compliance. In those graph displays they show more than a few bars where there were four or more sections shown in the daily compliance detail. On a few graph bars at the beginning some bars show multiple “potty-break” lines and some have more than 1-nap session recorded for a day.

From my compliance graph detail I think this means that there must be a time window that must expire before a sleep section is considered a “Session”. It might also mean that what I call a "potty-break" doesn’t figure into the session counting logic. For example, in the early days of "getting-hosed" I found I still needed naps during the day and I wasn’t yet sleeping through the night uninterrupted. On those days where naps happened, the machine (joy at working from home) shows them as clear session breaks with a lot of white space in between. However the "potty-breaks" only show as vertical black lines on the green compliance bar indicating something happened at that time, but the session didn't expire. The specifications, which are very vague, don't spell out what it takes for a session to expire before the machine considers a new session must qualify under the “3-sessions per day” rule.

An area I find to be just plain wrong in my machine’s specification is where it indicates it will preserve 7-days of "in-depth" data. My experience is that it only holds 5 to 6 days of detailed data and that is dependant upon how much detail happened during those 5 or 6 days of sleep sessions. Unfortunately, I discovered that data limit the hard way.

It will be interesting to hear back from Liz to see what she has to say about her break time length.

Hi Liz,

Thanks for the update.
Glad to hear that you didn't lose it.

Best wishes,

Roger and Den,
Thanks for the expalanation of what a "session" is in Respironicspeak.

O,

That's the only word I could think of to describe it.....not sure what Respironics calls it.

Please don't ask me to prove this because I couldn't stay in bed this long since being "on the hose".......BUT......

From analyzing this a little further since this thread began, it looks like in Encore Pro that a "sleep day" goes from Noon on day 1 to Noon on day 2. Encore Pro would (in my estimation) keep a continuous graph on that amount of time if your "breaks" didn't exceed 1 hour each. If they DO exceed one hour, it will start a new graph for the next "sleep session", but keep all of the "sleep time" recorded in that 24 hour period in a "green, time-line bar" (albeit broken up by the breaks).

Hope I didn't make it more confusing.

Best wishes,

Den

Is there any other reason than the "leak" reading that one needs to turn off the equipment when one uses the loo? It doesnt seem to hurt anything leaving everything on for a few minutes,
