ResMed S9 Escape & H5i™ Heated Humidifier - Standard Cpap Machine PackageResMed S9 Escape & H5i Heated Humidifier Standard Cpap Machine Package This machine is part of the S9 series which came out before the S10 series. The S9 is an older model. That's why we recommend starting with a Resmed Airsense 10 (S10) because it is the most up to date CPAP machine currently on the market. There are several models of the S9 such as the Vpap, S T, Escape, and the Elite. This model is the Escape model. INCLUDED: All items in picture
