I am 1st time user and really have nothing to compare it with but i can say it is so quiet machine that sometimes need to put my hand in front of the mask to see if it is on .easy to use ,assemble and program . color LCD screen ,EPR , Ramp and mask fit features .
Controls easy to use ,overnight data ,sleep report ,easy to view ,and to set the patient and the clinical menus .
No more rainout with the climate control ,the humidifier has a pre-warming setting and easy to use ,blow down period of turn off to dry out the hose ,the hose is light ,flexible and easy to move around and comes in a compact carry bag.
Heavy power brick ,easy to tear the hose near the cuff ,small noise at exhale ,no pause button,no software as it should be made available  ,the owner manual is not informative and it could improve with more instructions ,humidifier lid easy to come off the plastic hinges .
conclusion :
Well designed machine ,user friendly and with many options that can make compliance with the treatment much easier and more comfortable ,would recommend the autoset because it is like having two machines in one (one in cpap mode or auto titrating mode)and it is worth the extra cost .

RE: ResMed S9 AutoSet CPAP

[Image: attachment.php?aid=10]

I've had my ResMed S9 AutoSet for several months now, and I'm completely happy with it. In my opinion, unless you're going to go with a very sophisticated auto-BiPAP, the S9 Autoset is as close as it gets to perfection in the CPAP world.

Auto CPAPs aren't cheap, and I paid about $850 or so for mine several months ago. But, I feel this was a worthwhile investment in my own health.

Some good things about this machine are it's intuitive design - it's very easy to operate, and a couple of minutes in the instruction manual will get you up and running right away. Ease of use - that's important to me and many other CPAP users. The machine itself is very lightweight and small. Additionally, this machine is VERY VERY QUIET. In fact, when your mask is on, someone else in the bedroom will not even know if the machine is on or not. It's amazing to me how much they've reduced the sound levels of this thing.

The S9 Mask-Fit system runs a 3 minute seal integrity test, prior to therapy treatment. After 3 minutes, a Mask-Fit icon appears (a green or red smiley face). If the smiley face is red, adjustments are necessary until the smiley face turns green, then therapy will begin. Cute, and a nice feature, but not completely necessary.

The S9 units offer the optional Humidaire H5i Heated Humidifier with Climate Control. Since I don't use a humidifier, I can't really offer much here, other than to say many people seem to be satisfied with it. Using the optional ClimateLine heated hose is another option which many have found useful. There have been a few problems with early versions of the ClimateLine hose, but I believe ResMed has addressed these issues in their current run of ClimateLine hoses.

The S9 AutoSet comes with a SlimLine (non-heated) hose in the box. The ends of the hose are the same size as standard CPAP tubing, but the hose itself is slightly smaller in diameter. Good for folks who don't like bulky hoses. You can use the supplied SlimLine hose, or use a standard CPAP hose, no problem, the ends are identical, it's just the hose diameter in between that's different. Just remember there is a setting in the setup menu for type of hose, so you'll need to set that in order to maintain proper pressures.

You can use nasal pillows, full face masks or nasal masks with the S9, you'll simply need to set the type of mask in the machine setup menu system.

This machine comes with ResMed's "EPR" (Expiratory Pressure Relief) technology, which is a comfort feature that will decrease the pressure at the beginning of each breath and keeps the pressure low throughout exhalation.

I strongly suggest that most CPAP users should consider going with an auto-CPAP machine. You can read about the benefits of auto-CPAP HERE.

The real power behind this little gem is the fact that it's fully data-capable and you can use the optional (and free) ResScan personal computer software to extract data and generate charts to monitor and adjust your ongoing CPAP therapy. You can read about how to get the ResScan software for free HERE. (you must log in first) You just have to purchase a cheap SD Memory Card Reader for your computer (usually between $15-25) and you can then take the SD card out of the CPAP machine and download the data onto your PC for further analysis. An SD card is included with the machine. ResScan is wonderful - I suggest you use it if you get the S9.

If you want to learn more about the S9, there's a good video review at the bottom of this page:


That page also shows you how to enter the Clinician Setup Mode on your S9 unit, to change pressures and other settings you may find useful. If you do choose to change your prescribed pressures, make sure you read through this page and this page so you can do it safely and properly.

I really can't think of a lot of negatives for this machine. The only problem I've ever had in the past several months was that two times, the machine just shut off in the middle of the night, waking me up. Not a big deal, especially since it's been operating flawlessly at all other times... and the machine simply came back on after a few seconds and I was able to go right back to sleep. But this problem may have been caused by my sleeping behavior, not necessarily because of a machine malfunction.

I can firmly recommend the ResMed S9 AutoSet CPAP machine, and happily give it "5 stars". Smile

4 and 5
Great comprehensive review, Supersleeper! There is nothing to add except the changes in the detection algorithms and data management compared to the S8 model, which it replaces:
The S8 Autoset was limited to detecting leak, hypopnea, apnea and pressure and retaining detailed sessions for 7 days, as well as 365 days summary sessions. The S9 is able to record high rate graphs, (detail breath by breath flow graph,) and stores up to 7 of these high rate sessions on an SD data card. In addition it can differentiate between obstructive and central apneas and offers AHI, AI and CAI on the machines screen readout. With the ResScan software, the S9 can provide graphs for events (OA, CA, H,) pressure, leak, flow limitation, minute ventilation, AHI, and snore index, storing up to 30 such detailed sessions on the SD card. The machine retains in memory 365 summary session, as well as copying these to the SD card.

I rate the machine 4 stars with regard to data management only, because the competing Respironic product offers a few more data points, such as RERA and Periodic Breathing (Cheyenne Stokes.)

Overall performance, I rate five stars! The treatment algorithms are virtually perfect. In my case, all hypopneas and obstructive apneas are eliminated, leaving only central apneas, which, of necessity, are not treated. In comparison to experience with the older S8, my overall AHI index is reduced by 2/3. The S9 similarily reduced AHI by 2/3 compared to the Respironics PR S1 APAP machine which I tried for only a week. Of course, performance will vary according to user's conditions.

Having used both the PR System 1 auto with a-flex and now the Resmed S9 Autoset, I feel that the S9 by Resmed is the better machine...for me Amazing. My numbers while using the PR1 auto were around 2.8 which is still very good but with the S9 I'm getting 0.5 to 0.8 each night.

I find the EPR setting on the S9 works better than the a-flex on th PR1. The breathing feels almost completely normal while using the S9, whereas with the PR1 auto, I felt I was trying to time my breathing with the flow of the machine so that exhaling was easier.

The slimline hose that comes with the S9 is lighter and does not drag as much as the full size hose so it feels better when you roll over. The software for tracking sleep data is excellent and allows you to chart and graph your sleep for up to one year.

Overall I would have to say that this is an amazing machine and well worth trying if you are upgrading or in the market for a new machine.

We have video fitting guides, mask tips and tricks, flow generator features and capability videos, so hopefully it will be a valuable resource.

We have two playlists for the S9 series on the channel which may be helpful for folks that are fairly new to the S9 platform and would like to learn a little more about their device.


I hope these links are helpful.

Could I ask, as a newbie who is considering a Resmed S9 (having virtually zero trust in Philips, due to a way too long story to explain here Grin), what exactly you mean by that? What is the Philips doing better / what use is this 'RERA' information and 'Cheyenne Stokes'?

Thank you Smile

I would assume the data covering this would help to further determine what the event was and therefore assist in truly knowing how the treatment is working (or not).

Take a deep breath and count to zen.
