What does "Fraction of Night in Variable Breathing" mean? What is a good percentage?

Sounds like you are using MyEncore - because those are the exact words I use on the graph.

From the Respironics Patent:
"... The Auto-CPAP... relies on the ability to trend the steady rhythmic breath patterns associated with certain stages of sleep. When a patient is awake, in REM sleep, or in distress, breathing breathing tends to be more erratic, and the Auto-CPAP trending becomes unstable. It is, therefore, important to interrupt the Auto-CPAP if the patient's breathing becomes too variable...."
Once the APAP has decided you are in "variable breathing", the actions it takes are quite complex (according to this patent).

I have no idea what a good value is. I average around 33% according to MyEncore.

I simply take the variable breathing as a measure of how "peaceful" your night was. In other words its a measure of how much of the night you were not having slow steady breaths,

So derek, what I am getting is that the lower my percentage of variable breathing, the better I am sleeping?
