Jaswilliams as I appreciate your response. Would you care to explain the backup rate?

RE: pressure plateau
Backup breathing at a specified rate. It will attempt to initiate a breath at the specified interval

RE: pressure plateau
CPAPs and most bilevels respond to spontaneous respiratory effort initiated by the user. For these bilevel machines, if a patient does not spontaneously breathe, the device will just contiue to produce EPAP pressure until breathing resumes. Bilevel respiratory devices with a "backup rate" use timing or some other more intelligent algoritm to trigger IPAP pressure when spontaneous effort to breathe is not detected. This can cause the user to take a breath or even cause air to flow into the lungs as a machine initiated breath. There are lots of flavors like ST, ASV and ST-A, and all work differently. You will learn more by reading the Resmed Sleep Lab Titration Guide if you want to read it. All types of machines are covered. https://www.resmed.com/us/dam/documents/...er_eng.pdf

If you study this, you will become much better informed. Please use the information carefully until you fully understand it.

RE: pressure plateau
Thanks sleep rider.... greatly appreciated.

I'm sure at the sleep study this will be found out....and machine adjustments made as study progresses. But in past posts the ASV has been recommended. But NOW, which BTW I asked my DR. if I could get a ResMed ASV and he agreed, I see it's too early in the game to want a particular machine. The sleep study will tell me what I need.



VERY cool website.... the mode of ventilation chart is very cool !

RE: pressure plateau
An example to help explain the machines a bit. Consider this info about machines that I gleaned on my self research. Don't worry, it's not deep.

The thing is as I understand what you're dealing with, if you allow an assumption, and if that assumption says you need a machine capable of dealing with CA as the major need. You may also have other apnea events. Today's choice is ASV. Before the ASV, the best choice was probably ST-A.

I have used a ResMed AirCurve 10 ASV for about 2.5 years. It is capable of dealing with apnea related events including OA, CA, Hypopnea, and I will also say Flow Limits as mine was near zero FL quite consistently and I'm COPD. ASV may or may not be best for UARS, PLM, etc. and/or events that aren't apnea related. Also, if you have other breathing issues like COPD, then ASV may not be the best choice as I had found out.

Again, I am not stating what device you need or don't, nor am I talking in reference to any of your symptoms in this one specific post. Just a bit of info on my knowledge of the ASV and o from a guy that used it.
