Vent flow rate. - The Happy Dreamer - 03-10-2012

When looking at my download report, does the leak or vent flow rate go up as the pressure goes up ?

ResMed S9 does a good job in calculating leak and shows just mask leak (unintentional leak).
Respironcis is a bit complicated for me it shows total leak (intentional leak + unintentional leak) so to work out mask leak have to subtract whatever leak is showing from your mask vent leak.

So the flow rates of the mask does show up in the leaks chart? that means that as the cpap pressure goes up so does the leak rate, right?

I don,t know what SleepyHead shows for leaks but vents leaks (intentional leak) can vary with pressure as the charts in the above link shows but the mask leak (unintentional leak) depend on how good the mask fit at any pressure.

my sleepy head V0.9.2-1 beta shows total leaks. there is an option to show total or unintentional. before the update it showed it a couple ways.
