Leak Lines

Post by JQLewis » Wed Sep 24, 2014 8:37 am

Why do some people's charts in Sleepyhead show two different leak lines? Mine only shows one. I've looked for an option for this, but I haven't seen one.

short answer, they have a different type of machine.

long answer, resmed s9 shows excess leak only,

PR shows total leak only, then sleepyhead does math and stuff and tries to approximate the excess leak based on the behavior of the flow.

it shows both the total leak, and what it calculates as probably the excess leak.
