Onkor Reading - Need help interpreting.

[Starlette]

Can someone help me interpret what I'm seeing?
I especially want to know what the two gaps in breathing mean.

Thanks.

At first glance it appears like a break in therapy like turning off the machine but obviously pressure and leaks have no gap. What does your Encore report say? Does it show the same thing?

Onkor shows a similar 45 minute gap in my flow recording on Saturday early am, around 3 am also. The same data viewed in Sleepyhead shows only ~ a 5 minute gap, and I know I had a bathroom break right there (after waking up with a really dry mouth). I think maybe there are a couple of flaky values in the flow data that Onkor can't handle, so it just leaves a gap in the flow until it finds something interpetable. I'll try to get the plots posted here from both Onkor and SleepyHead so you can see the difference...
Here's Onkor zoomed in on the gap

and here's SleepyHead, same time frame (but slightly different scaling)

Strangely, neither program seems to get it completely right! And the only break I remember is the one at about 3:22-3:25
(this is of course SleepyHead 0.8.4 that jedimark is still working on, so there may be graphing anomalys there... but I thought Onkor was pretty stable and reliable?)

There may be a slight problem with session files (when we turn off the machine for a bit and then restart) getting combined properly with Onkor or SH that doesn't occur in Encore.... Not sure. I don't understand all the inner workings of sessions, times, combining and such. Respironics has had Encore for years... Onkor and SH are just babies in terms of age. I think they both are quite remarkable for what they do give us.

Milw. I screwed up on pictures. I didn't show everything.
I'm going to remove picture above and do it correctly, bear with me.

[Starlette]

OK Milw, ready for review.

It really looks like machine glitches to me, since the graphs don't show breaks in the pressure graph and the leak graph. I happened to be wearing the oximeter during the gap in mine, but spO2 was pretty much fine and only one pulse spike during the period, so I don't think anything much was going on. I tried opening mine in Encore Pro as well, it showed only one little block of 'breathing not detected' and refused to show any flow data from earlier than 3:25 am (after the break ended).

Thanks for responding milw, ty very much.

RE: Oximeter
Can we wear them all night to get an oxygen reading?
Are we limited as the nights per week of use?

Mine is CMS50E

[milw]

I have the CMS50E also, it can record up to (I think) for 24 hours, so I just download the data in the morning after each night of recording. It works pretty well to record the whole night, tho mine has fallen off a few times in the middle of the night. Someone else mentioned wrapping a piece of medical tape around it to keep it in place, I think that would work pretty well except for sticky tape residue on the screen. My skin was irritated the first night or two but I got used to it pretty quickly. Unfortunately with the 50E you have to set the time at the start of each recording session, or else leave it at 00:00 and just write down what time the recording starts at.

I'm not real happy with the 'glitch' explanation, but if it is the machines electronics or sensors, it will probably start happening more and more frequently. My machine is only a few months old, and I would hope it will keep working for it's full 5 year life!
