Innovative ResMed S9 AutoSet CPAP defines comfort, reliability and above all sound sleep in a new ultra-quiet, attractive CPAP package. The new S9 AutoSet combines its Easy-Breathe Technology along AutoSet algorithm to battle sleep apnea and allow people to breath more "natural" during sleep. New features include: periodic reminders of accessory replacements (e.g., mask, filters, etc.) as well as a mask fitting tool, SlimLine tubing and advanced data compliance reporting. New design has a feel of a modern CD/Clock radio instead of the sterile CPAP machine.
