Pressure build up
Hello, can anyone please offer some suggestions as to why the unusual pressure build up at 1.53am on the attached chart below? I had just switched to a Resmed F20 medium memory foam mask that night to minimise leaks.
kind regards, Joe

RE: Pressure build up
Easy, the flow limits did it.
You have EPR on Ramp Only, change it to Fulltime. Also see the cluster of Obstructive events. They imply a positional apnea, most likely from you tucking your chin in toward your chest. Try 1 vs 2 pillows or a flatter pillow
