First OSCAR graphs, mask issues? - djhvyc - 02-07-2021
Hi all, please find my daily chart for last night below. It looks like I had some mask leakage issues driving my apnea? When I hit REM my jaw slackens, and even though I use chin strap/mouth tape I believe air is finding a way out of my mouth. I have a superior chin strap on the way that could improve things, after that maybe look into a full face mask?
Let me know what you guys and gals think. Pressure is set at 8.0 because I can't fall asleep with FOT active and my breaths are too long for even timax 4.0, so even though I use a VAuto it basically functions as a CPAP.
Sorry, screencap is attached

Your machine settings are totally bizarre for an Aircurve 10 Vauto. Fixed pressure of 8.0 in VPAP-S mode. Wow, you realize this is flat-out CPAP, right?. Are you ready to make this thing work properly? According to your chart your Ti ranges from a median of only 1.68 and a 95% just over 3.0 seconds, and with pressure support it will be shorter. Show me past results in Vauto mode because I'm skeptical whether you had workable settings.
Go into settings:
Mode: Vauto
EPAP min 8.0
PS 3.0
Max IPAP pressure 15.0

You're in the best of hands with Sleeprider; do use the settings he has recommended. Your leaks are fine, unless they are waking you up. And there's nothing to suggest they're driving your apnea.
After you've tried your new settings and posted another chart or two, it'd be worth considering whether a tighter pressure range would serve you better, since you feel you may be sensitive to pressure changes.
Although your leaks are fine, it's good to experiment with a new chin strap. You might also consider reinforcement for your tape if you have an idea where it may be loosening. I use Somnifix tape, with some reinforcement using Fixomull stretch tape (very inexpensive). Also be sure you're drying your lips and pursing them (turning them inward) before you apply your tape.
