Leak Rate Waveform - BrassCat - 04-08-2020
Hello the forum. Thanks for all the support.
I am confused concerning my leak rate waveform. See included screen shot.
I would understand the lower line indicates the current leak rate. Makes sense.
The upper line I am understanding would indicate the ACCUMULATED leak
volume. But it starts out high. I would expect it to start at zero and slowly rise!
Obviously I am misunderstanding what this line represents.
Best help, Stan

Total leaks includes the air flow through the mask vents. You can turn it off under "Preferences" under "File" at the top. Click on the "Waveforms" tab.

Note that, for PRS1, the CPAP and BiPAP models only report the total leak, and OSCAR is estimating the unintentional leak from that. I have no idea how accurate that estimate is.
The ASV and S/T and AVAPS ventilators all report the unintentional leak as well as the total leak.

Agreed. That's one of many of attributes of channels that we'll want to add. (Another being whether the channel is an average interval that should be drawn as a square wave plot vs. continuous data that should be a linear graph. This varies by manufacturer.)
