OSCAR Question About Pressure

[MurrayNevada]

I've been on this board for years but away from OSCAR for quite some time. In the pressure chart from last night there are two lines, one above the other. Can someone tell me what the difference is between the lines?
Thank you

Top pressure line is the inhale pressure.
Bottom pressure line is the exhale pressure.

You must be using EPR or exhale pressure relief.

If you weren't using any exhale relief you would see one single pressure.

See the gnomon at upper right? It says one is EPAP, one is Pressure. Helpful? Not so much!

Looks like you have EPR 2 turned on... that's all it is. On my Aircurve it just has one straight line all the way across, they don't even bother with EPAP.

Thanks folks. Your help is always appreciated.
