The ResMed S9 series offers an intuitive, colorful, and stylish look. With four clearly marked buttons and a large color display, adjusting settings has never been easier. A large push dial allows you to scroll through screens and make changes easily. The large color screen allows you know where you are scrolling and what setting you are adjusting by changing colors. The info button allows you to view compliance data and reports with a single push, and the large start button offers an easy one touch start. The sleek low profile design makes your CPAP look less like a sterile medical device and more like a standard bedside clock radio, further encouraging you to be consistent in using your therapy.

The S9 AutoSet combines an intelligent algorithm with Easy-Breathe expiratory pressure relief (EPR™) to dynamically adjust pressure for maximum comfort. Using ResMed's time-tested APAP technology, AutoSet continually monitors breathing, adapting breath by breath to always deliver the lowest therapeutic pressure, improving comfort and sleep. The S9’s enhanced AutoSet algorithm now differentiates between obstructive and central sleep apneas (CSA) and responds appropriately. You can be confident that you're always receiving optimal therapy at the lowest, most comfortable pressure.

ResMed introduces its new SlimLine Tubing with the S9 series machines. Exclusive to ResMed the SlimLine Tubing is 40% lighter, 20% thinner, and takes up 35% less space. Providing more flexibility and less drag with light weight materials, the SlimLine Tubing promises to be a favorite among CPAP users. In addition to this, ResMed introduces a smart-fit cuff design that makes it easier to attach and remove the tube from your mask and machine.

By enhancing the Easy-Breath motor with axial air-flow, foam, and noise isolating materials, ResMed has created an ultra quite CPAP machine. Measured at 24dBA (that’s no louder than normal breathing!), you or your bed partner will never be awoken by your noisy CPAP machine.

Both the S9 AutoSet & the S9 Elite have CSA and OSA detection. The enhanced Easy-Breathe motor features small diameter lightweight impellers that provide lower inertia. This enables the motor to track your normal breathing waveform and produce the small oscillations in pressure required to detect CSAs. It uses the forced oscillation technique (FOT) to determine the state of the airway during an apnea. When an apnea is detected, small oscillations are added to the pressure to measure airway patency. The CSA algorithm uses the resulting flow and pressure to measure airway patency and differentiate central and obstructive events. Your S9 AutoSet has the ability to compensate for these events with its enhanced autoset algorithm.

All the S9 series machines come with onboard and removable data storage. With a touch of the info button you will see a snapshot of your therapy. Data is stored on board for up to 365 days and includes average usage, used hours, days used, run hours, pressures, leak and AHI information. The removable SD card provides detailed graphical data and high resolution flow data that your physician can read.

By reducing pressure during exhalation, the patented EPR Easy-Breathe technology makes the adjustment to CPAP therapy easier and more natural for the user.

Do you ever have trouble knowing if your mask has a sufficient seal? With the Mask Fit option, your machine will run a quick diagnostic to let you know if your seal is sufficient. Simply select what type of mask you are using (Full Face, Nasal, or Nasal Pillows) put your mask on, from the Home screen push and hold the dial for three seconds. Your machine will perform a short 3 minute diagnostic and you will see on the display an “Adjust” or “Good” indicator, letting you know if you have a good fit.

I have been using this machine for two months now and it is far superior to the two standard type machines that I have utilized over the last 12 years...The autoset automatically sets the pressure to fit my needs which changes depending on my sleeping position, breathing pattern, congestion , and fatigue....I wouldn't trade this machine for quality of sleep has improved dramatically...THANK YOU RESMED

It's exactly as described. Extremely quiet. I had a much noisier machine for many years but I've quickly gotten used to this one.

I have been using this machine since September 2011 and have had no problems. I appreciate the quiet comfort that it provides. When travelling, I sometimes use it separate from the H5i and climate-line tubing and while not the same experience; it provides the quality sleep that my occupation demands.

I have been using this machine for 3 years. Very happy with it. It is much quieter than my first machine. Make sure to get the humidifier to use during winter so your throat does not dry out.

I tend not to give total credence to reviews on newly purchased products. From past experience, some products performance and durability have a tendency to drop off dramatically over time. After almost two years of service I give it a total (thumbs up)!! It has worked flawlessly, and it's ability to automatically change with my breathing needs far surpasses my three previous units. I want to thank the engineers responsible for its' development.
