I'm curious about Periodic Breathing (PB) and/or Cheyne Stokes breathing (CSB). Is it normal to have PB/CSB breathing patterns during the night? Is it typically more prevalent durning one sleep stage than another? At what point (as in percentage of the night) is PB/CSB acceptable? And is "CSB-like" ...

My apologies to all. From the PR S1 Pro with Auto IQ information page on the Philip's web site: "Clinicians can opt to use all 30 Auto-Trial days up front or choose to use fewer trial days and save the balance for a later date if the patient’s condition changes. For example, if you choose to use onl...

Well, let me recant a bit. You may need to know the Clinician's control code to "reset" the machine back into Auto Test mode.

The rep may just assume that a pt would never be able to get into the mode to reset it.

The rep doesn't know what he is talking about. The following is an excerpt from the machine description from our host (https://www.cpap.com): Auto-Trial Phase Auto-Trial Phase monitors and adjusts pressure on a breath by breath basis for up to 30 nights. The goal of the Auto-Trial Phase is to use br...

Thanks, Pugsy. Good heavens, there is a lot to learn.

Interesting discussion. From the experience of the community, can a CPAP pressure set slightly too high result in both CA's and Cheyne-Stokes breathing?

Thanks,

tHANKS for the feedback with the ASV.

Is that why the ResMed only allows the Quattro FF mask?

Edit.. I just opened SH 0.8.3 and PR S1 ASV machine is listed as being supported.

Yeah!

That makes sense because there is a notation in some of the documentation that the SD card cover needs to be replaced if using a modem or other module.

So would the data on the PR S1 ASV be able to be displayed by Sleepyhead QT?
Thanks.

Hi, all! I've been on CPAP for about a week. I have tolerated the Mask and pressures fine...so far. CPAP has almost completely eliminated my OSA. The problem is that I have almost the same AHI because of CA's. There is a nightly increase in the number of Cheyne-Stokes and pattern breathing. The RRT ...

In my anxiety to get a seeable chart I don't know if I even posted the "best" wave section of the SDB pattern.

snippet did it. Thanks.

I'm trying. I took a snapshot of the screen. [cntrl][prtscr]. Pasted that into Paint. Saved as a jpeg. Uploaded to photobucket.com and that's what I got. Suggestions on how to make it bigger? Thanks.

Okay, Here's the nap chart...I hope.



I'm not sure what a sleep diary is. I'm usually too tired to write things down at bedtime.
Thanks.

Hi, all. This morning was just the second night on CPAP. 1st night was with Quattro ff mask; last night with Mirage Liberty (Hybrid). 1st night: AHI + 3.91; Hypo= 2.05' OA=0.63; CA=1.26 ;RERA=1.10; PB/CSR-0.8% 2nd night: AHI=15.66; Hypo=5.31; OA=1.46; CA=8.89 ; RERA=0.53; PB/CSR=1.19% I wish I knew ...
