Over the past month or so, I feel like the pressure my CPAP produces has become less than it used to be -- judging by how the air venting out the front of the mask feels, and also how my ears don't pop as much as they used to when I turn the machine on. And I've been feeling tired more, and my wife tells me she heard me snoring the other night.
It's still showing the same pressure setting as always, but I've been traveling a lot, so something might have gotten damaged. I'm not seeing any other signs of damage, though.
Is there any way I can test what pressure it's actually putting out? Or is it worth just pre-emptively seeing if I can get it replaced under warranty?
Unfortunately, the machine's a dumb brick, so I can't get it to tell me whether I've been experiencing apnea more than usual.
