How important is the mask fit? I have had no benefit from my CPAP treatment (in fact I feel more tired) and consulting my doctor about changing the pressure has made no difference.
The only thing I can think of is that maybe my mask (full face) isn’t a good fit, but then my CPAP does not record any leaks.
Could a poor-fitting mask (even without leaks) ever impact on CPAP therapy? Or would it have to be a significant problem (e.g. massive leakage) to be capable of impacting on CPAP therapy?
