Pressure=Stats
#1
Sleepyhead show me Mask Pressure and Pressure: mask pressure typically runs lower-Why?

What is the difference between the two?
I get a third reading in the RES MEd software, Why is that?

Which one correlates best to the pressure setting on my machine?

I'm not totally sure but my understanding is this: Pressure is recorded as the nominal output from the flow generator. It is a low resolution record, with a sampling rate lower than one per second. What is charted is therefore only an approximation of the actual pressure at any given time. The mask pressure is high resolution data, recorded near as dammit to real-time. It shows all the little ups and downs which occur, such as the pressure dropping for EPR and the little pressure pulses when the machine is trying to diagnose an apnea. ResScan refers to this trace as Pressure (High rate) which is the same as SleepyHead's mask pressure.
