CPAP only showing 3–4 hours of usage

Hey everyone,

I’m a little confused and hoping someone here has experienced this.

My CPAP machine keeps showing that I’m only getting about 3–4 hours of usage per night, but I know I’m wearing it for at least 6–7 hours. I put it on when I go to bed and don’t consciously take it off during the night.

I don’t wake up much, but I guess it’s possible I’m removing it without realizing it.

Has anyone dealt with this before? What should I check first: mask fit, leak rate, settings?

Appreciate any insight. This is still new to me and I’m trying to make sure I’m actually getting full therapy.

Thanks in advance
