As part of ResMed’s S9 series, the ResMed S9 AutoSet™ CPAP Machine offers PAP users a sleek and stylish look. Its large color display and clearly marked buttons makes adjusting your settings simple and easy. A large push dial allows you to scroll through screens and make changes, while the large color screen lets you know where you are scrolling and which settings you are adjusting. The info button allows you to view compliance data and reports with a single push, and the large start button offers an easy start with just one touch. The S9 AutoSet’s sleek, modest design makes your CPAP Machine look less cumbersome and more commonplace, encouraging you to be consistent with your CPAP therapy.

The S9 AutoSet™ CPAP Machine 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 breath to adapt to each inhale and exhale, delivering low pressure to improve your comfort and sleep. The enhanced  algorithm also differentiates between obstructive and central sleep apneas (CSA) and is able to respond accordingly.

The S9 AutoSet™ also enhances the Easy-Breathe motor with axial air-flow, foam, and noise isolating materials. This way, it has created an ultra-quiet CPAP machine that measures at 24dBA (which is quieter than a whisper!). With the ResMed S9 AutoSet™ CPAP Machine, you are guaranteed both a restful, serene sleep environment and optimal therapy at the lowest, most comfortable pressure.

ResMed also introduces their new SlimLine™ Tubing in the S9 series. The new SlimLine™ is 40% lighter, 20% thinner, and takes up 35% less space. With more flexibility and less drag, this new tubing promises to be a favorite among CPAP users. In addition, the S9 AutoSet™ CPAP Machine introduces a smart-fit cuff design that makes it easier to attach and remove the tubing from your mask and CPAP machine.

Like all S9 series machines, the S9 AutoSet™ CPAP Machine comes with onboard and removable data storage, which allows CPAP users to see a snapshot of their therapy with the simple touch of a button. Data is stored on board for up to a year and includes AHI informationaverage usage, days used, leaks, pressures, run hours, and used hours. The removable SD card also provides detailed graphical data and high resolution flow data for your physician to read.

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

ResMed’s S9 AutoSet™ CPAP Machine also provides the perfect solution for PAP users who have trouble knowing if their mask seal is sufficient. With the Mask Fit option, your machine will perform a quick diagnostic to let you know if your mask is sufficiently sealed. All you have to do is put your mask on, then select the type of mask you are using (Full Face, Nasal, or Nasal Pillows) from the Home screen. Push and hold the dial for 3 seconds and your machine will perform a short 3 minute diagnostic and you will see an “Adjust” or “Good” indicator on the display. This will let you know if you have a good fit.

    What you read is exactly what you get. Love how quite the machine is. I have use plenty of machine and a lot of them much nosier.

    I am somewaht new to the machine. I’ve only been using it for a couple of months, but so far is superb. Much better than the other two machines I used for the past 9 years. Best thing for me is the machines auto sets the pressure to adjust to my needs depending on the position I am sleeping and my breathing patterns. I would never go back to any of the others machines after trying this one.

    Awesome machine. By far the best machine I’ve tried in my 10 years of cpap treatment!
