Second night, same thing so I went to the DME to make sure I was putting it on correctly. I was. DME gave me a small cushion, threw in an extra SD card and a case to put it in.
Third night, started out with the small cushion. 2 hours, as far as I know, all was okay. Then, 2 times, the tubing popped off of the mask and it was leaking like crazy. Went back to the medium cushion to see if I got better results. It kept leaking and the tubing popped off as well as the top head gear on the right side (where the forehead piece is). I woke up to my tubing on the floor and the machine running (not sure how long that was going on before I woke up).
Has anyone else experienced this? Respironics has authorized the mask to be sent back as defective and they will replace it so that isn't a problem.
