The ResMed S8 Escape II CPAP is an upgrade to ResMed highly innovative Escape I model. The new redesign features a much more compact and quieter unit (only 24 dBA, quietest in the current marketplace) and contains an improved motor design which allows the machine to provide the individual with superior performance without compromising therapy compliance. The Escape II model comes with ResMed's patented EPR Easy-Breathe technology which helps to reduce pressure during exhalation and as a result makes CPAP therapy much easier and more natural for the patient. Available with or without H4i Heated Humidifier.
