Mask Pressure in Sleepyhead
#1
I've searched on here and other sites but can't find the answer. I see in a number of posts that people using Sleepyhead have a graph showing mask pressure. For some reason, I cannot get it to display for me. I'm not sure if it is because of the machine I'm using (PRS1 560) or some other reason. It is selected in Sleepyhead to display, I've verified that.
The reason I am interested in this graph specifically is because I use the FitLife mask and I just wanted to verify actual pressure at the mask since it is such a large mask.

Unfortunately, the PRS1 units do not produce that piece of telemetry. ResMed units do. ResMed units give the mask pressure on a breath-by-breath basis, so for example you can see the effects of EPR on the pressure profile. PRS1 units only give the pressure setting for constant-pressure CPAP units or the current instantaneous auto-pressure setting for auto-CPAP units.

Now, to my knowledge, the "mask pressure" on ResMed units is not actually a measured value at the mask. It is the instantaneous expected pressure value at the mask, given the machine's understanding of which mask is being used.

Thanks for the reply. That solves that issue.
