Learn More About Your New Machine

The S9 Elite is a sleek, all-in-one system that is ideal for any nightstand. Users can take advantage of EPR settings and Easy-Breathe Technology to drop the pressure upon exhalation so that breathing feels more "natural". The machine is fully customizable with reminders for accessory replacements like your mask or machine filters. The S9 Elite can also display advanced therapy and compliance data through the color display.

Key Product Features

  • Intuitive Design
  • Mask-Fit System
  • Optional Climate Control Heated Humidifier
  • SlimLine or (Optional) ClimateLine Tubing
  • EPR with Easy-Breathe Technology
  • Smart Start / Smart Stop
  • Auto Altitude Adjustment
  • On-Display Advanced Data Reporting

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 the S9 machine, 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 helps prevent 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 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.

EPR with Easy-Breathe Technology

Easy-Breathe technology softens the breathing cycle by monitoring the user's breathing pattern. Along with EPR, the S9 Elite synchronizes the user's inspiratory and expiratory cycle. A smoother, more natural delivery of pressure keeps the motor whisper-quiet when operating. Easy-Breathe allows the S9 Series to operate at 26 dBA when set to 10cm of pressure from a distance of one meter. The overall reduction in motor operation helps keep conducted noise from traveling through the tubing and away from the mask. No more motor whining and noise generated inside the CPAP hose.

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 lasts longer than 10 seconds, EPR stops until the event concludes and normal breathing with EPR resumes.

EPR with Easy-Breathe technology also allows users to customize the RAMP feature. Set the S9 Elite to EPR RAMP ONLY mode to enhance comfort and help improve compliance. Users are more aware of pressure changes as they fall asleep, using pressure relief during the ramp period naturalizes this process.

For more information on all these technologies, check out ResMed's Tech Fact Sheet.

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.

Standard Menu

  • Usage
  • Mask Fit
  • AHI
  • Period
  • Days Greater than 4 Hrs
  • Average Use
  • Total Used Hours

The Advanced Menu displays all the above plus:

  • Days Used
  • Pressure
  • Leak Rate

Deciding which S9 Machine to Choose

To see a detailed comparison of the different S9 CPAP machines by features, please see our CPAP Newsletter: Understanding the S9 Line.

Compatible Hoses

The S9 line of machines come with SlimLine hosing which has a 15mm diameter. A standard (22mm) hose can be used with the S9 machines, however the Patient Setup Menu must be accessed and the "Tube" setting changed from "Slim" to "Standard". If a ClimateLine hose is attached this setting is automatically changed accordingly.

Power Supply

The S9 Series can use (2) different Power Supply units, a 30 Watt or 90 Watt external brick. S9 machines come standard with a 90 Watt Power Supply that can power the CPAP machine and Humidifier. The 30 Watt Power Supply will only operate the CPAP machine and the humidifier will act as a passover.

The DC Converter 24V/90W For S9 Machines allows this machine to be used with battery power.

Humidaire Cool Down Feature

All S9 Series machines utilize a "Cool Down" feature that runs the CPAP Motor up to 1 hour after turning the machine off. The motor helps to cool off the humidifier plate. You may hear a "faint blowing sound" when you turn the machine off. However, you can unplug the power cord and allow the heater plate to cool without airflow.

H5i Humidification Level

The H5i Heated Humidifier has three modes: Patient, Auto and OFF. These settings can be accessed under "Climate Control" through the Clinical Menu.

When the H5i is set in Auto mode it will measure the amount of humidity in the room and heat only as much as needed to reach the optimal moisture level of 80% and then stop heating and go into a cool down mode. When the H5i again senses the need to raise the humidity to 80% it will begin to heat.

When the H5i is set in Patient mode it will heat in the traditional manner until it reaches the desired setting of humidity or 80%. The H5i can be set from OFF to 6 and is adjusted from the HOME screen.

The maximum level of humidification is 80% whether using the SlimLine of ClimiteLine Tubing.

ClimateLine Tubing Information and Use:

  • Tubing Options: ResMed's S9 Elite has a number of tubing options. The SlimLine 15mm tube is a non-heated tube in a thin, flexible style. The machine can also be used with an OPTIONAL heated ClimateLine Tubing which integrates with the machine and OPTIONAL H5i Heated Humidifier to provide increased humidification and reduced chances of rainout. The ClimateLine is available in two diameters. The SlimLine 15mm ClimateLine Tubing and a standard diameter 19mm ClimateLine Max Tubing. Additionally a standard diameter, non-heated tube may be used.

  • ClimateLine Tubing Lengths: A traditional CPAP tube is 72 inches long. The optional 15mm ClimateLine Tubing length is 78 inches. The optional 19mm ClimateLine MAX Tubing length is 75 inches.

  • Installation of the ClimateLine: The ClimateLine attaches to the back of the machine using the same port as a standard hose. The electronics connection is below the port and may be covered with a protective flexible rubber cap attached the machine. Place the machine so the back of the unit housing the filter and hose connection is facing you. After removing the rubber cap, orient the hose so the electronic tab is facing toward the filter. Push the tubing end firmly onto the port, then rotate the tube clockwise to fit the two electronic connections together.

  • Removing the ClimateLine: To remove the ClimateLine from the back of the machine, rotate the hose counter clockwise. The electronic connections disengage allowing the hose to removed. Cover the machine's electronic port with the flexible rubber cap to protect the connections.



ClimateLine Tubing Lengths

A traditional CPAP tube is 72 inches long. The optional ClimateLine Tubing length is 78 inches. The optional ClimateLine MAX tubing length is 75 inches.

Please Note: If an O2 Enrichment Adapter is used with the ClimateLine Heated Tubing for the S9 Series of CPAP machines, the O2 Enrichment Adapter must be placed between the ClimateLine tubing and the mask instead of between the S9 Humidifier and the hose, in order for the ClimateLine tubing to work correctly.

SmartStart Note

Per the manufacturer, the SmartStart auto on / off feature of this machine may not function as intended when used with a nasal pillow mask and a pressure setting of 7 cm H2O or less. If this feature does not appear to be functioning with this type of mask and pressure setting, this comfort feature can be turned off. Please refer to the User Guide for more information.

The S9 is so quiet, I kept removing my mask to see if it was working. My wife is very impressed with its silent running. I can see many years of enjoyable sleeping ahead. Thank you.

Good choice for an upgrade

Verified purchase | Aug. 29, 2015 | Verified CPAP.com Customer
Very pleased with my upgrade to this S9 Elite. My old Resmed M Series had less options and is a lot louder. My wife likes it that it is much quieter and the exhale is less, a nice thing if I am facing her. The S9 Elite also offers more user adjustments. I am trying different air pressures to fine turn my sleep quality, this way I do not need to make an appointment with Apria who controlled the old ResMed I owned. The only issue I see is the filter and filter cover could have been designed better to make it more efficient and lock down better.
