Excessive air leak?

[JoeS01]

Hello, would anyone please like to comment on the air leaks of my mask in the attached screen print? Is it normal or excessive? I  have a Resmed Airfit F20 mask which tends to squeeze the corners of the mouth and purse the lips a little bit.
Given the AHI is only 1.99, does the leakage really matter?

The spikes on your leak rate graph indicate mask movement, which I think you are probably aware.

Although your overall leak rate is low, it has caused you several breaks in therapy, which in turn can't possibly give you a great night even with a low AHI.  

The higher flow limitation matches with the mask leaks.  You'll need to fix the mask leak or mask movement.  Read through the mask primer.

Many thanks OpalRose, much appreciated

flow limits are what you need to fix.  Flow limits are what raise the pressure of the Resmed machine.  

to help with the flow limits we use EPR but you also need to raise the min for the EPR to work.

Turn on epr to full time
set the min 7
set EPR 3

that should help the raise in pressure and in turn help stop the leaks.
