Y-Axis question

Y-Axis question
What is the best Oscar settings for Y-Axis scaling mode; is it best to leave them at Auto-Set or set narrower perimeters? Suggested settings would be appreciated.

RE: Y-Axis question
I have Flow Rate and Leak Rate set manually. Flow Rate because if I take a real deep breath, or yawn, it will increase the scale and makes it harder for me to read my normal rate.
Leak Rate because I have OSCAR set to 24 L/min as a LL and a much larger leak will, again, make it harder for me to read the scale.
Flow Rate I have set to -70 to 70, and Leak Rate I have set 0 to 30. YMMV...

The rest I believe I left on Auto Scale.

RE: Y-Axis question
That depends. Normally, the Auto-fit option is the first choice. Sometimes, on a day-to-day basis, I've noticed that some graphs will over constrain the data by using limits that are larger than needed. That's when I will set the limits manually. After viewing the data, I will return it back to the Auto-fit. The Pressure graph comes to mind. I use EPR and don't have the EPAP option turned on for this graph. On some days OSCAR will want to include a displayed range that is inclusive of the lower pressure of the EPAP. This causes the graph line to be displayed in the upper half of the graph. This oddity is sporadic at best and I haven't found a way to consistently reproduce it.

Bottom line is, play with it. You can always reset the graph back.

I hope I answered your question.

Auto scaling is a thing the OSCAR team will be looking at, not this upcoming release.
