Oscar graph axis units

Oscar graph axis units
I love OSCAR but find it curious that there are no units displayed on the graph axes (viewed under DAILY tab.

Might you point me to a document describing the "Units of measure" on the graphs ? ....... for X and Y axis

Thank you

RE: Oscar graph axis units
All values, other than respiration, are measured in metric.  The pressure is measured as centimeters of H2O displacement.  The volumes are measured as either milliliters per hour or liters per hour.

You can find more information in our Wiki. The link to it is at the top of every page.

With your mouse, hover over the y-axis. A pop-up window will show more information on the y-axis and show the units.

In a few cases, units will be shown as "?". That means the data reported by the CPAP machine is in an unknown scale.

RE: Oscar graph axis units
Thank you for your quick response.

Green and red curves on the "Time at pressure" graph are not clear to me. One is for pressure and the other one is for EPAP.

Is there something written already that will explain their relationship?
I don't want to be a pain to you.

First time at pressure is one I rarely look at as it means little to nothing as I evaluate chart.

EPAP is exhale pressure,
Pressure is Inhale pressure and is often referred to as IPAP.

We see the difference on the pressure chart.

The time at Pressure graph display the time in minutes that is spent at a specific pressure (bucket).
a pressure bucket is a range of pressures (pressure +- 0.1).
