I've been using a breeze headgear (nasal pillows) with a DeVilbiss 9000 CPAP machine. It is set at 11 lbs of pressure and I have not been using the ramp. I have used the machine all night, every night for the past two weeks with good results. I feel so rested. However, I have a heavy feeling in the upper part of my chest and daytime shortness of breath with and without exertion since using the machine. Has anyone experienced this. I have no other symptoms such as chest pain, arm numbness, etc Any suggestions? Will this pass with time?? Is it concerning/serious??? I appreciate any enlightenment anyone can offer.
