ResMed S8 Elite™ II CPAP Machine with H4i™ Integrated Heated Humidifier

See Details
If you are purchasing a new CPAP, Auto CPAP or BiLevel (BiPAP) machine, humidifier or an oxygen concentrator, then federal law requires that we receive a copy of a prescription written by your doctor. A sleep study report does not qualify as a prescription.  Also, the purchase of complete CPAP masks does require a prescription.  (*** Note that the component parts that make up the mask DO NOT require a prescription! ***)
The prescription must state that it is for CPAP therapy and at what pressure your machine should be set. If you are purchasing a standard CPAP machine (one that operates at a constant pressure), then the prescription must show one pressure setting, which is generally a number between 4 and 20 and measured in cm of H2O. If you are purchasing an Auto CPAP machine, then your prescription must state two different pressures: A low (minimum) pressure setting and a high (maximum) pressure setting. If you are purchasing a BiLevel machine, then your prescription must state two pressure settings: An inspiratory (IPAP) setting and an expiratory (EPAP) setting.  If you are purchasing an Oxygen Concentrator, the prescription should have the flow rate stated in Liters per minute. 
Prescriptions can be faxed to us at 888-469-2555, or we can accept a scanned copy of your prescription by emailing it to us at [email protected].

Please note that orders for machines, concentrators, or complete masks will NOT be shipped until we receive a copy of your prescription!

About MIRP Pricing

** Note - we are frequently asked what the difference is between the ResMed S8 Elite II and the S8 Escape II models.  They are essentially identical machines, except that the Elite II records detailed data pertaining to the patient's breathing patterns, pressures and leakage rates, whereas the Escape only records usage and compliance data.  Both machines now offer EPR, which offers some "softening" of the pressure when the patient begins to exhale.

ResMed has made some key design changes to their already excellent S8 platform of CPAP machines to make them even better. 

First, they developed a unique low-inertia, dual-stage motor that rotates at much lower speeds than motors in traditional CPAP devices.  Being dual-stage allows it to perform more efficiently at the lower speeds, resulting in exceptionally low noise levels of 26 dB.  This revolutionary motor is also encapsulated in a protective silicon envelope that partially inflates with air and further isolates the unit from shock and vibration.  ResMed wraps it up in a durable thermoplastic housing for additional protection and sound-deadening.  This produces a machine that is noticeably quieter than its competitors.
