S9 vs. PR System One Auto

[SleepingUgly]

Is software available legally for the S9? If so, would anyone who has the S9 be willing to go to the trouble of posting some pages of what the output looks like?

Do you lose the daily details after a certain # of days? (eg, the PR1 will only report daily details for one week)

Do you think it is an issue that the S9 does not detect clear airway apneas (i.e., central apneas)? Would I be sorry I didn't have that if I end up trying to titrate myself at home?

How quiet is the S9 relative to the PR1?

Does anyone prefer the Cflex (or Cflex+) exhalation relief over the EPR?

I've seen people mention that the Resmed machines post leak data relative to 0=no leaks, but is that only true if you're using a Resmed mask?

Are there any advantages the PR1 has over the S9, or conversely, any disadvantages the PR1 has that the S9 doesn't?


I have the PR1 but have never used anything but Respironics, so I don't know if I would prefer the S9 (and I may be in the position to swap it out). Things I don't like about the PR1:

The Clear Airway tests puffs may be part of why I have difficulty with masks such as the Hybrid (It's just a hypothesis, but I think the puffs happening inside my nose may be more disturbing to my sleep than when they happen on my face, but I've had too many issues with traditional FF masks).

The noise of the PR1 is inconsistent, and the variable whining/drilling/3 note melody can be annoying.

I don't like the 7-day and 30-day averages reported on the LCD, nor the "large leak" (I could leave it blowing on the pillow, and it would still not say I had a large leak). With software this is less of an issue, but it would be great if I could just look at the LCD and see what happened the night before and only download once a week. This is not a deal breaker.

To those who respond, please note whether you've tried your S9 in both Auto and CPAP mode.

Thanks!

you can easily see the S9 report samples from dave21 postings on S9 - in fact more than enough

Hmm. Th S9 DOES detect centrals - not sure why you think it doesn't. I haven't heard any S9 user complain about puffs of air either. I switch the EPR off on my S9 as I believe in APAP mode at least it is unnecessary because of the Resmed easy breathe technology.

The S9 keeps detailed data for 30 days; summary (compliance) data for 365 days and also has high-res data for 7 days.

The S9 is silent - can't hear a thing.

The S9 asks for the mask TYPE - ie nasal, pillows or full face so I think it should work OK with any brand mask.

The S9 will shut the machine off if there is a large leak - if AutoStart is enabled. There is no leak alarm.

I have only ever used APAP mode.

I use EPR at 2 cm... also in CPAP mode you have an option setting Inhale to Med or Fast... Fast is standard and I like the Med setting which is a bit smoother, I think. It is really dealing with the transition of inhale to exhale. I have tried only C Flex and I didn't like it all - it didn't seem to match my breathing pattern. I turned it off.

On the S9 it tests for centrals by pulsing 1 cm of air in 5 bursts. I had 3 last night and did not notice anything ever. It is not a "puff" that I can feel.

You can read the LCD daily for all detailed info, leave the SD card in the machine and once a week place the card in the PC to DL all data - Summary, Detailed and Breath by Breath Hi Rez... no problem.

S9 is silent - completely ( although some were annoyed by squeaking dial) Mine never has.

Haven't tried FF masks. I think with FF mask... on the S9, you cannot enable the autostart/off function.

Only CPAP

The S9 is so easy to breathe with that when I awake during the night - I forget that I have a mask on. I know that everyone who has an S9 sounds fanatical... but it really seems that good. Time will tell if the great numbers that everybody is reporting is exactly how they feel... but I feel better just putting it on...

First of all the S9 does indeed detect and report on central apneas.

Second of all why would any machine try to clear a central apnea?
A central apnea is where your brain does not send a signal for you to breath (this was the short easy definition), increasing pressure will not help because there is no blockage.
If you are having too many centrals then you need a machine other than a c-pap or a-pap machine.
Did your sleep doctor tell you that you had a central apnea problem? What did your sleep study results say?

Almost everyone get some centrals but too many centrals like too many of any kind of apnea event is serious and should be diagnosed and treated properly.

Was your message directed to me? I don't think the machine should try to clear a central apnea. I was asking if it was a "con" for the machine to not detect them (and apparently it does detect them, so this is a mute point). The intent of my question was that if I were to try to titrate myself at some point, would it be useful to see whether the pressure is INDUCING central apneas? Of course this assumes that the way these machines estimate central apneas is at least somewhat accurate.
