Can someone help me figure this out

[fredn]

Last night I got this "spurt" of obstructions .....

I went to sleep at 8:10 PM ..... these started a little after 9:00 PM .... it was the biggest string of the night

Any idea what caused this or what was going on .... I woke up shortly afterwards (around 9:14 PM) to hit the bathroom ....

Not too sure, but maybe check your mask fit?
The leaks not too bad, it is under 24, but sometimes the machine doesn't pick up events when there's leak.
The events seem to appear when the leak is better later on. Kinda suggests to me that there may have been a leak earlier masking the events?

Did it happen all night or just this period?

I wouldn't worry too much

Are you wearing a full face mask or nasal mask? The leak pattern later on kinda looks like some mouth leak?

Fred,

Any chance you moved into an odd position? Whatever the trigger was, I see the leak rate dropped dramatically right at the start. That almost looks like you rolled over or moved your head to a place where your neck was kinked and blocked your airway. It is a pretty impressive effect...you almost totally stopped breathing during that short interval.

All in all, it appears that the machine adjusted upward, and the events stopped. However, the damage was done...your O2 level dropped enough that your body made you wake up by telling you that you had to go to the bathroom. If this happens more than once every blue moon, then you might want to switch from auto mode to fixed pressure levels. Had your machine not had to ramp up, you might not have had any events, or if you did, they might have been hypos rather than OA events.

Since you are digging in kind of deep here, have you considered getting a pulse oximeter? It would be interesting to see how your O2 level does in general at night, and it would have been especially interesting to see what your O2 level did here as well as your pulse rate.

Hey John .....

Right up my alley Can you recommend a couple to look at?

I ordered a CMS-50F .......

Fred,

That will do the trick. I have the E model, but I find that I have to tape it to my finger to keep it on overnight. A co-worker that also uses CPAP has the F, and he really likes it.

I'm puzzled by the leak rate. It was rock solid, but into the intentional leak range, then it dropped. That makes no sense. Is the proper mask type entered into your machine? I'm having a hard time figuring what kind of unintentional leak would be that high, but not vary up and down more than that.

I wonder if you somehow blocked the exhaust vent at the point where things go squirrelly.

I think the leak was high to begin with and wasn't picking anything up? And when the leak dropped it sensed events? Can't be 100% though the leak later on looks suspiciously like mouth leak???

You need to show a longer term of sleep than 30 min to draw conclusions. Besides the higher leak at the beginning which looks like a small tear in the air hose all other looks valid. If an S9 can't diagnose an event b/c of leak it flags it as unkown in yellow like this:

(Unknown events on S9 Elite b/c of leak in the air hose tear)

FWIW...the leak line appearing to be bottoming out...I have been able to duplicate that on a graph with intentionally blocking the vent.

There was another post recently with a similar question, and that's what I suggested as well ... perhaps the patient rolls over such that the vent is pressed in to the pillow or something else. Zero leak, but that means CO2 builds up. Ultimately this wakes patient up.
