My pressure goes up to 20. According to my titration, I need a pressure of 19 to stop all apneas. I reach 19, sometimes awaken, probably not breathing and definitely experiencing leaks.
I'm losing a lot of sleep time readjusting mask to stop leaks. I'm tightening both top and bottom but don't want to make mask too tight.
I was using a full face FP 431, now using Quattro Mirage full face which I find to be somewhat better for leaks but not by much.
I'm not sure how tight the straps should be in order for me to breathe well without leaks.
Which full face masks handle high pressure best?
