If your dad has a CPAP machine and still snores then it’s not doing its job. Either:
He’s not using it
He’s removing it halfway through the night
The mask is not fitting well
Can’t help with the first case. In the second case, it can happen reflexively if the air is too warm or too dry. Is he using the humidifier feature?
For the fit part, he might want to try a different type of mask (eg nasal pillow if using a full mask or vice versa). Different types of masks may also be more convenient for certain sleep postures, which as you already discovered can make you more or less prone to snoring.
I should clarify, I have no idea if it helps with his snoring. My understanding was the CPAP helps with the sleep apnea, snoring is its own thing. I just seem to remember my mum saying he was still snoring, I could be wrong.
That said, I’ll ask him about it, I’m pretty sure he is using it. Case 2 or 3 might be things.
