what's that sound?

[joem18b]

sometimes - and more often recently - when i'm just barely asleep or perhaps when i'm woken up by, a whooshing sound, as if the cpap is pumping air freely down the tube or ??? As soon as I breathe in through the nose pillows, the sound stops. Can someone tell me what that is? Doesn't seem to do any harm, but it always catches my ear. thanks.

sounds like a leak.

I would guess you just opened your mouth.

I have your same APAP.
Sometimes, if you don't enter an humidifier well, it happens that the outlet seal does not make a good seal, and when the pressure goes up, you hear a hissing sound that can vary with respiration.
Try to control this.
