    Enhanced AutoSet: The ResMed S9 AutoSet will automatically adjust the pressure and provide the exact amount of pressure required from breath to breath with the least amount of pressure required. With the ResMed S9 AutoSet you’re certain to receive a tailored experience every night to suit your specific needs.

    Climate Control: The optional H5i Heated Humidifier uses intelligent humidity controlling technology to offer optimum relief from dryness and congestion. The H5i easily connects to the right side of the S9, making this a true integrated system. The S9 will automatically detect when the H5i is connected and provide you with setting options on the main color screen. Humidity levels can be adjusted Using the S9's settings screen. An even greater level of comfort can be reached when using the optional ClimateLine Heated Tubing. Five sensors throughout the S9 system monitor the ambient temperature and airflow. The ClimateLine heated tubing also has a temperature sensor to ensure perfect relative humidity at the mask. The water chamber that comes with the H5i Heated Humidifier can be opened for easy cleaning.

    Expiratory Pressure Relief (EPR): EPR allows the S9 AutoSet to breath with you, not against you. The EPR feature decreases the pressure at the beginning of each breath and keeps the pressure low throughout the exhalation. The pressure is then automatically increased during inhalation. This comfort feature can be easily adjusted by the user to a reduction in pressure by 1, 2 or 3 cm. A setting of 3 would reduce the pressure during exhalation by 3cm. In this example, if the inhalation pressure was 10cm, the exhalation pressure would drop to 7cm. The EPR feature also incorporates an event detection circuit. Event detection insures the EPR will stop if a breathing event is expected or has occurred.

    Taking Quiet to the Next Level: Taking Quiet to the Next Level: The S9’s enhanced Easy-Breathe motor features foam and isolating materials incorporated into the base of the device. Both radiated noise and noise through the tube remain at a low 24dba noise level. Thanks to the Easy-Breathe Technology, which helps monitor your breathing patterns, a smooth natural delivery of pressure is achieved.

    Mask-Fit System: The ResMed Mask-Fit check system will effectively help ensure proper mask fitting. You can preset any mask type and run a quick 3 minute seal integrity test. The Mask-Fit icon will then appear and display a green or red smiley face. If the face is red, you can make adjustments to the mask.
