S9 vs. System One

[ddk]

Resmed S9 or System One?

Which do you think is better and why?

I've used the latest of both for a month each and I think that the S9 beats the S1 by 20,000 leagues + 1. I'm not complaining, mind you, as I got my machine through Medicare for free and it's been a life-changer. But if I could afford my own, I'd absolutely and without question get the Resmed over the Resperonics.

I think there are pros and cons to both. Personal preference. They have all been discussed at length here.
Didn't vote.

I'm satisfied with my PR System One DS560. It is the only machine I've tried, so I can't offer any value in a comparison.

[LSAT]

I think most people have only used one of these machines...no way to compare. The S9 users will vote S9 and the S1 will vote S1. Useless Poll.

I'm starting my own test today.

I just got a System One 60 Series APAP machine and I'll be using to see if its better than the S9 Autoset I had been using.

I happen to have used both brands. It's a toss up for me. Couple of minor pros and cons with either but none a deal breaker. Pretty much equal treatment feelings and sleep feelings. I like them both pretty much equally.
So I can't vote unless I do the lemon vote just to see what the others say.

I've got both. I agree with pretty much everything Pugsy said about them, including the tossup part.

There might be a significant difference when it comes to bi-level CPAP and for people with UARS, which I believe is my case. That would be the System One BiPAP Auto and the ResMed VPAP Auto 25 (I've tried the S8). After a couple of weeks on the System One, I had AHI of over 30 (after years on a Respironics Bi-PAP Pro), then after switching to my current S8, the AHI went down to nothing (under 0.5).

The difference is the responsiveness to the transition between exhalation and inhalation: on the System One the sensitivity is not adjustable and is rather low. On the S8 you have five levels to choose from and the highest is so sensitive, it almost works like a ventilator. For people with significant obstructions in the nasal passages, the pressures that the machine is set to are rather irrelevant as the actual pressures to your lungs are very different because of the fluid dynamics, and getting them right is subject to a lot of tweaking. The S8 has all sorts of settings that help with that; the Respironics has hardly anything. And they also have very differing approaches to auto-pressure calculation (e.g., limits on pressure support), although they are not sufficient to get that part to work for me.

But, I guess, if you are talking constant CPAP, then there might be no difference - after all, there isn't much to it.

Actually I am talking Bilevels. In my case I have both the PR S1 BiPap Auto and it's counterpart in ResMed the S9 VPAP Auto. Well over 6 months of use on each one. It's still a tossup for me.


I do think that there are going to be some people who will do better with one brand's way of doing things over another.
I don't think it is common but it is kinda of hard to have much of an idea about that part because not many people get a chance to use both brands and actually compare them.
I do think that most people would find that either brand will do the job and work well.
Some people like yourself might do better with a specific brand. Burkebang didn't do well with the S9 Autoset algorithm. Someone else might do better with it.

The number of people who have actually had a chance to use different brands of machines is not very great. It's a pretty pricey experiment. Most people simply think their machine is the "best" because they have no way to compare it to the other brands. Their happy and that's the way it should be. The mind is a powerful drug and if it starts second guessing that the machine that is being used is not the "best"...let's face it, we all want to be using the "best"...then the mind will play tricks on a person and maybe they won't feel so good.

[Uncle_Bob]

I have both but when you say "better" I can't help but let the cost factor creep in.
people getting machines through insurance won't notice.
But people paying out of pocket will, I got my PR ONE at around half the price of my S9.

I tried an S9 for 30 days. I did not like the humidifier. The one I had could not be taken apart for cleaning - at least I couldn't find a way and neither could the DME. It was also harder to fill to the proper level.

It comes with this one now. Dishwasher safe tank. Or at least mine did. Bought it one week ago.

[ClayL]

My trial period was about a year ago, so they must have changed it since then. That looks like a big improvement.

[archangle]

I understand the S9 "non dishwasher" tank has been redesigned to be openable as well.

Because my first and only System One unit was the bargain basement clunker, REMstar SE, I was extremely disappointed. It was awkward to use, the buttons had a tendency to stick, and it was not user friendly at all. I was able to trade it in for the somewhat more user friendly S9 Escape. This still doesn't give off all the technical data I would like but it's vastly superior to the SE. Besides, the clinician manual for the SE is still not easy to acquire and I had no idea how to even make the simplest modifications. Because I feel they really botched up on my sleep study it was up to me to find a reasonable pressure to set my CPAP to. So far my experiment of 9.2 (up from 8.0) is working adequately. And I don't believe I'm snoring anymore which is a real bonus.

But I hated the REMstar SE.
