[Pressure] 4/25/2

4/25/2
I use a ResMed S9 auto and just had a new sleep test (5th one in 12years) the study came back with a pressure set 4/25/2. Could anyone explain what this means? Thank You and have a Blessed Week

Welcome to ApneaBoard markds!
Not sure what that means, but someone else will probably chime in soon and give their opinion.

RE: 4/25/2
My guess would be starting pressure/max pressure/pressure relief?
But I'm a completely n00b with this so take it with a grain of salt. 25 is really high for pressure, if this is true.

RE: 4/25/2
Exactly which S9 do you have? Look near the start button. I bet it says VPAP Auto.
The Autoset cannot run up to 25 cm-H2O. But the VPAP (bilevel) can. The Rx looks like min EPAP is set to 4 cm-H2O. Max IPAP is set to 25 cm-H2O. And PS = 2 cm-H2O. It won't go up to 25 cm-H2O unless it scores events that result in it "thinking" it needs it. Admin Note:

Looks like it was set at 12/16 before, was not sure what the third number means. This is my 4th machine in 12 years and trying to learn more about it as I'm not getting very good support lately from the health care company.

This is my 4th machine in 12 years and trying to learn more about it as I'm not getting very good support lately from the health care company. The 2 means it will maintain a constant split between EPAP pressure and IPAP pressure such that IPAP - EPAP = 2. This is called pressure support. While always maintaining that difference, the IPAP and EPAP pressure can auto range such that EPAP is always greater than or equal to 4 (EPAP min.) And IPAP is not greater than 25 (IPAP max.) The doc has set your machine wide open -- given it free reign to operate over a wide range of pressures. In the future, when a data pattern has been established, that window may be narrowed. Get one or both sets of software for your machine. Follow your therapy; and look at the flow, pressure and event graphs in context to with the other graphs. Admin Note:

Mark, consider what your last machine was set at and whether you can tolerate such a low staring pressure. While the machine is an auto bilevel, starting too low can be uncomfortable and give you a sense of air starvation. If you are accustomed to higher pressures, you may want to bump that EPAP MIN up from 4.0.
