All I can assume is that somehow the machine is designed that way. I had thought that EPR was suspended when events were being detected and that the pressure was then held constant at the prescribed level, which is the pressure level at the tops of the peaks on the mask pressure graph.
EPR also has a 15-Second Rule.
Got any longer apneas?

Each "double hump" is a breath. The part of the breath above the "0" line is when you are inhaling. The part of the breath below the "0" line is when you are exhaling. The "O" line is the line that cuts the humps in half.
¿Qué?
And yet, that 35 LPM bias just happens to be the same as the Leak Rate of an HC431 FFM @ 10 cmH2O.
A coincidence?
Or are mysterious forces underfoot?
