Question on OSCAR Mask Pressure Readings
On most of the OSCAR graphs, the displays appear to scale with the data received.
The Mask Pressure display appears to have a range of 10 to 16, with a maximum reading of 15.88 when the values appear to go off the scale.
How is the data derived for the mask pressure display?
RE: Question on OSCAR Mask Pressure Readings
The mask pressure data comes directly from one of the detailed data files.
If you want to change the scale of any graph, you can right click between the numbers and the name of the graph on the left end. a menu will open allowing you to change the upper and lower limits, and add some dotted lines at various values.

This is a bug in the CPAP machine itself -- it is not reporting mask pressures above 15.88. See Note 2 about this problem in the section listing Philips Respironics machines in http://www.apneaboard.com/wiki/index.php...d_machines.

Thanks for the explanations. It is a 900x machine. That explains the dashed line along the top of the graph.
