Rebreather pressure/volume (PV) diagram

Ant Slegg · 29th March 2006, 09:23

The Boris manual has (on page 6 of the version I have) the following:

"The rebreathers pressure/volume (PV) diagram is normally like a sideways ellipse,as you breathe out it starts from the bottom left and moves to the top right. The reverse is true on inhale."

Although I'm fairly sure I understand this (and the rest of the description) they do say that a picture paints a thousand words so I was wondering if anyone had the picture?

Did you want specifically a Boris PV loop or just a general PV loop?

A general one would have been fine, the link is Boris specific and will allow me to re-read the manual with the aid of a picture.
