I’ve been using a CPAP for a number of years but recently switched physicians. The previous one was not responding to my continued fatigue and I found using software that I was experiencing a high number of apneas.
I use a full face mask and do obtain a good seal. The new provider is encouraging the use of a chin strap to close my mouth even though I am using a full-face mask. I don’t understand why this is being encouraged. Will ask for clarification at next visit but that isn’t until October. [Yeah, could go in earlier but not worth it for just this question.]
So why use a chin strap to close the mouth with a full-face mask?
