So, the mask pressure is actual *measured* pressure... if you have a big enough leak that the machine can't maintain the desired pressure, then you'll see a drop in the mask pressure. Just looking at that by itself isn't as informative as I'd wish, i want to see the mask pressure *and* the flow rat...

My guess is that you may in fact be occasionally inhaling or exhaling deeply and sharply enough to trigger some fluctuation in the Mask Pressure that is just (barely) big enough for you to perceive as the mask collapsing onto your face. But without seeing the Flow Rate graph, together with the Mask...

That only makes it more of a mystery....

I'm pretty new to oscar, where can i find mask pressure?

thanks. Mine seems way more erratic than yours, even though it stays between 945 and 1045, for the most part

I upload my data in sleephq heres the link * the phenomenon happened within the last few minutes I was wearing the mask. https://sleephq.com/public/29e5416d-492e-4ef8-aefd-d386019245d1 The last 30 minutes of this night look like this: http://i.imgur.com/gZLuMXi.png Seems to me that you most likely ...

Doctors are trained to treat the patient--not deal with the devices, which are updated frequently--and every model is different. You need a clinical technician for that. Duh! Since there are none available, we amateurs do the best we can- -because we HAVE TO. And thank God there there are very well...

You can find the mask pressure in the chart selector at the bottom right of the screen. http://www.apneaboard.com/wiki/images/7/79/OSCAR_daily_screen.png The "other platform" is SleepHQ, which is a web-based program somewhat similar to Oscar. The advantage of SleepHQ is that you can create and post...

Ramp is on More important(ly), EPR is off. You might want to include Mask Pressure in your images and note where the phenomenon occurs. I'd recommend using that New Platform that's out there but be aware it's buggy (like reporting critically low oxygen levels when in fact they're normal). EPR is of...

Its doesnt happen every breath I'm seriously impressed with everyones knowledge. Even just working the problem, even if the "educated guesses" that may be off, the fact that people are working through it is amazing to see thanks you all for your willingness to help out At this stage we're all more-...

Sreiter, do you have EPR turned on? I can recall people complaining of the mask "pulsing" between inhale and exhale. The problem went away when EPR was turned off and they just received a constant pressure. I have no idea :( - I'll have to ask my doc. thanks for bringing it to my attention EPR is a...

Forgive me if I'm not supposed to post the stuff on the left hand side.
