I have used both models now and prefer PR 560. And it is mainly because of the way it senses apner. ResMed sends a series of air puffs too fast in my opinion. Respironics sends a larger air puff but waiting a little longer before sending it. As I breathe very slowly so disturbed me by ResMed's puffs.

I am trying to pick (next week) without of course having anything but Internet info to go on. <sigh>

My first approximation was to choose the ResMed S9 due to what I perceived as a (possibly) superior heated/humidity control in the optional hose and the fact that I am already set on using an F&P Oracle HC452 Oral Mask which is supposed to be more sensitive to humidity (and heat) issues.

After reading the above description of the algorithms (and being a programmer) my tendency was to change to Respironics RemStar 60 Auto for the following reason:

My sleep study didn't get a titration so I am really dependent on the Auto to find a therapeutic level.

I am pretty sure that the study machine started on 4 and that was way to low (as far as I can tell with my lack of experience.)

After two hours of calm, quiet, even comfortable waiting I called the tech and he upped the pressure, to 6 I believe -- and that seems a little better but still too low.

After one more hour (3 total) they kicked me out and I never fell asleep for titration.

My doctor ordered the machine with 4-20 as the setting (wide open.)

The S9 Auto sounds like the algorithm doesn't deal well with a minimum pressure that is WAY too low.

Give the likelihood that 4 (or even 6) is low for me and that behavior of the algorithm it leads me to wonder if the RemStar Auto isn't a better choice.

I am thinking about calling the doctor's office (actually I tried but their phone line is out today due to the ice storm I suppose) and asking specifically if he will consider upping the minimum pressure to (at least) 6 -- or tell me if I am full of it.

It will make me sounds like an "Internet Doctor" but hey, it's my deal and I want to succeed at this.

Does the Remstar Auto 60 have the same data capability for reports as the S9 though? You want to think a bit long term as things can and do change over time.

From the original comparison earlier in the thread, they sound very similar but like with every else there are some differences:
Data
Both machines record full efficacy data, including the wave form, events, and leak data. The S9 shows an incredible amount of detailed summary data right on the LCD; the System One does not. Both machines work well with SleepyHead. It is possible to get your hands on the "official" software from Resmed and PR if you want it.

There are some differences in how the two machines record the efficacy data however.

First: The Resmed S9 overwrites the wave flow data on the SD card every seven days and the other "detailed" daily data every 30 days. If you want all the data, you must download it at least weekly. The PR does not ever seem to overwrite the detailed data, so when you download to SleepyHead you'll see everything that's been written to the card. (But Encore will only download the last night's wave form for some silly reason.)

If you forget to put the SD card back into the S9, the machine will write the summary data to the card when you insert it, but all the detailed data will be lost. If you forget to put the SD card back into the System One, the machine will write all the data except the wave flow to the SD card when you put it back in to the machine. (Both machines write the wave flow data directly to the SD card.)

The Resmed S9 is very picky if anything is written to the SD card by the computer system---this is a problem if you use a Mac or a Windows 8.1 machine and you forget to "lock" the card before inserting it into the computer. The PR System One doesn't seem to care much about things the computer might write to the card. I routinely forget to lock my System One's SD card when inserting it to my Mac and I know the mac writes some hidden .files when I do that. The System One doesn't care.

The snore data and the flow limitation data are recorded as continuous functions on the S9; they are discrete tick marks on the System One. (SleepyHead's version of the snore data is very different than Encore's version of the snore data from a System One machine.)

Both machines flag apneas (and classify them as OAs or CAs) and hypopneas. The System One also flag RERAs (respiratory effort related arousals) using a proprietary algorithm and periodic breathing. The RERA flagging is a bit controversial since a RERA requires an EEG arousal to be scored in the lab and the System One obviously does not have any EEG data to work with.

Finally, you can change the clock in the clinical menu of the S9 and nobody can change the clock on the System One. Both machine's have some problems with clock drift over time. There are some bugs in ResScan where clock drift was apparent back when I was still using an S9.

If you're talking about data that is recorded to the SD card and that shows up in a software program like SleepyHead, then the data recorded by the PR Series 60 System One Auto CPAP is equal to the data recorded by the Resmed S9 AutoSet. The data available on the machine's LCD screen each morning is still more limited on the Series 60 System One, but not as limited as the Series 50 System Ones.

Both the Resmed S9 and the PR System One record:
  • AHI data, with the apneas broken down into CAs and OAs
  • Full wave flow data---both machines record every breath you take all night long
  • Leak data
  • Snores, although the way the two machines record snoring is different
  • Flow limitations, although the System One only records flow limitation data when run in Auto mode. The way the machines record flow limitation is different though
The ResScan reports data on the respiratory rate, minute ventilation, and tidal volume; these are all derived from the wave flow data and JediMark has programmed SleepyHead to calculate these numbers for System One machines as well as the S9s. SleepyHead also reports inspiratory time and expiratory time for both machines because that too can be derived from the full wave flow data.

The System One flags periodic breathing; the S9 does not. But if you know what you're looking for and periodic breathing is significant issue for you, it's not that difficult to identify when it might be happening visually.

The System One flags RERAs based on evidence of one or more recovery breaths following a period of increased flow limitation. The S9 does not attempt to flag RERAs since a PAP machine has no EEG data.

The S9 reports "pressure at mask" which allows you to see EPR in action; but whether this graph provides any information that is not provided in the pressure graph and the wave form mask is a good question. In my opinion, the MaskPressure graph doesn't really provide any useful data.

And the PR System One does NOT overwrite the detailed wave flow data every seven days and the rest of the detailed data every 30 days the way the S9 does. And the System One doesn't seem to be as picky about hidden files written to the SD card by the computer's operating system as the S9 is. Those are actually pretty important considerations if you don't plan on downloading the data on a very regular basis.

In short, although many people around here think the S9 is somehow superior to the System One in terms of data, the reality is that the data gathered by the System One is as good (and perhaps slightly better if RERAs are an issue) than the data recorded by the S9.

My rep told me that resmed is eventually going to stop making the s9.
Not sure how long it will take but the a10 is now their go to unit.

well, now there's a surprise! (given that the no longer make the s6, s7 or s8 models

robysue - Thanks for your awesome update. This is my 1st post. I've been lurking for a couple of months looking for advice to help me decide which machine to get (I'm overdue for getting a new one). Really appreciate the help!

The most recent Resmed Model is Airsense 10 Autoset, available in standard and "For Her" models. If you are getting a new machine, you may want to be looking into that model too. This thread was started before the Airsense 10 Autoset model was available.
