→Problematic Leak/Total Leak Lines
These are leak lines where it's clear that Large Leaks are present during a significant amount of the night, but it's not clear if the Large Leaks last long enough for the machine's manufacturer to say they are a problem.
The manufacturer with the clearest definition of when Large Leaks become long enough to adversely affect the quality of the CPAP therapy and the accuracy of the data is ResMed: ResMed's infamous '''''Mr. Red Frowny Face''''' shows up indicates on the machine's Sleep Quality Report when the (excess) Leaks are AT or ABOVE 24 L/min for at least 30% of the night. So we'll assume that if the time in Large Leak is approaching 30% of the entire night, the Large Leaks are problematic.
So a good working notion for a Problematic Leak/Total Leak line would be the following:
A Problematic Total Leak line is one that is NEAR or IN the manufacturer's Large Leak Territory for somewhere between 20-35% of the night; A Problematic Leak line is one that is ABOVE 24 L/min for somewhere between 20-35% of the night. A Problematic Leak/Total Leak line indicates that the leaks ''may'' be both '''long enough''' and '''large enough''' to have an adverse affect effect on the quality of your therapy and the accuracy of the data.
The Statistical Leak data for a Problematic Leak/Total Leak line will typically have a median Leak/Total Leak number well below the the manufacturer's definition of "Large Leak", but the 90% (or 95%) leak numbers, will be larger than the official Large Leak definition.
If you see a Problematic Leak/Total Leak line every now and then, there's no point in worrying about it. If you see Problematic Leak/Total Leak lines a lot, however, you may want to consider taking measures to address the leak issues.
