The S9 AutoSet is the premium Automatic Positive Airway Pressure (APAP) model in ResMed's S9 Series. ResMed had incorporated Easy-Breathe Technology along with an Enhanced AutoSet algorithm to make breathing through a CPAP feel more "natural". Major improvements can be seen throughout the system with advanced features like the Optional H5i with Climate Control, ClimateLine heated tubing, and on-display advanced data reporting.
Product FeaturesThe AutoSet series of Automatic Positive Airway Pressure (APAP) machines have long been designed to maximize comfort while providing minimal therapy pressures at the optimal moment. ResMed builds upon the AutoSet Advantage algorithm and incorporates EPR with Easy-Breathe technology in a new post modern shell. The S9 Series aesthetics are a complete redesign with new features:
- Key Product Features
Mask-Fit System
ResMed has incorporated a simple and effective tool for help with proper mask fitting. The Mask-Fit system allows users to preset a mask type, tailoring the S9 CPAP therapy to a particular mask style:
- Nasal
- Pillows
- Full Face
Once set, the 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.
Optional Humidaire H5i Heated Humidifier with Climate Control
ResMed has re-invented the Humidaire line of CPAP humidifiers. The Humidaire H5i incorporates an intelligent humidity controlling technology. The Climate Control system is managed through a combination of S9 machines, H5i humidifier and ClimateLine heated tubing. There are five sensors throughout the system that monitor ambient temperature and patient airflow. The ClimateLine heated tubing uses a built-in mask temperature sensor to reach relative humidity at the mask. Sensors inside and outside the CPAP machine closely monitor changes in humidity and prevents condensation from forming inside the tube. Rainout can hinder CPAP therapy and affect compliance. With the H5i humidifier, set the level of humidity and attach the ClimateLine tubing to achieve a new level of comfort.
SlimLine and (Optional) ClimateLine Tubing
The S9 Series CPAP machines come standard with the new ResMed SlimLine Tubing. The small diameter air tube is ultra-light, flexible and provides a unique alternative to bulky, generic 6 foot hoses. ResMed also offers a Standard Hose.
The ClimateLine Tubing has an internal heated coil and mask temperature sensor that helps manage rainout throughout the hose. Climate Control algorithms measure temperatures from the humidifier to prevent condensation from forming. The ClimateLine Tubing can use the SlimLine Tubing Wrap to achieve total control of rainout.
Enhanced AutoSet Advantage
ResMed's AutoSet Advantage is the answer to providing 'just what you need, when you need it'. Pressure needs vary throughout the night. These variations depend on how deep the user is sleeping, body position, and other daily factors that can affect therapy levels. AutoSet Advantage effectively minimizes therapy and helps lower pressure-related side effects, like mouth-breathing and nasal dryness. The AutoSet Advantage has always provided a strong defense against a main types of sleeping events:
The Enhanced AutoSet Advantage now detects and responds to open events using an event responsive Forced Oscillation Technique (FOT). A different event response is generated when an open airway event is encountered.
AutoSet Algorithm
The AutoSet algorithm measures flow limitations such as snoring and apneas on a breath-by-breath basis. Therapy begins at a minimal pressure. When the user's airflow shows signs of flow limitation, the AutoSet algorithm gently increases pressure based on the intensity and duration of the event. Once the event clears, pressures gradually decrease over a 20 minute time frame. Flow limitation occurs as the upper airway begins to collapse, before snoring and apneas are detected. By gradually increasing therapy pressure, the AutoSet algorithm reacts preemptively, resulting in lower average treatment pressures.
For example, as you sleep on your side, pressures will stay at a minimum because your airway is open. Turning on your back can collapse the airway and the AutoSet algorithm will increase the pressure. The AutoSet algorithm recognizes other conditions like sinus colds or allergies, which restrict nasal airflow. The AutoSet Advantage will increase treatment pressure accordingly, for whatever flow limitation may occur.
AutoSet with Easy-Breathe Technology
The S9 AutoSet uses Easy-Breathe Technology along with expiratory pressure relief (EPR) to make breathing through an APAP feel natural. At the onset of a flow limitation, the AutoSet algorithm responds with an increase of therapy pressure based on the degree of airflow restriction. Easy-Breathe technology aids in smoothing the pressure waveform during pressure increase. The process imitates normal respiration and ultimately makes breathing more comfortable than traditional CPAP machines. Easy-Breathe allows the user to receive the lowest pressure necessary to keep the airway open.
As an added benefit, Easy-Breathe allows the S9 Series to operate at 26 dBA when set to 10cm of pressure from a distance of one meter. ResMed also managed to reduce the overall conducted noise that typically travels from the machine, through the tubing, and at the mask.
Expiratory Pressure Relief (EPR)
EPR decreases the pressure at the beginning of each breath and keeps the pressure low throughout the exhalation. The pressure is reduced by an exact pressure drop of one, two or three centimeters of water pressure. EPR gradually changes therapy pressures so there is little ventilatory effect. EPR also has an Event Detection Circuit. When a sleep disordered breathing event is expected or has occurred, EPR stops until the event concludes and normal breathing resumes.

SmartStart / SmartStop
SmartStart / SmartStop enables your device to start automatically by breathing into the mask. This feature automatically starts and stops your CPAP machine when you put on or take off your mask.
On-Display Advanced Data
There are two menus that provide users with information about compliance, therapy and machine settings: Standard Menu and Clinical Menu. Both can be reached by using the "Info" button on your machine, but the Advanced Info Menu will only appear if the machine is in its Clinical Mode.
