Covidien/Puritan Bennett Sandman Duo Bi_level Machine with 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!

Prescription Required

The Sandman Auto™ CPAP device was designed to be highly accurate, comfortable and intelligent in order to deliver optimal auto CPAP pressure. This premium CPAP device has pressure and flow sensing capabilities that detect apneas, hypopneas, inspiratory flow limitations and snoring so it can react with optimal pressure at all times, while only increasing pressure during obstructive events. The patients™ critical data is stored internally for easy analysis with the optional software, while the auto-calibration feature provides precise pressure delivery for nearly all mask and tubing combinations.

Like all Sandman™ therapy devices, Sandman Auto is simple to operate and robust. It has backlit front-facing screen and buttons so that patients can make simple adjustments without needing to sit up and turn on the light. It is lightweight, has an integrated power supply, single power cord and unique integrated heated humidifier for more comfortable therapy. Designed to help sleep apnea patients comply with therapy, the Sandman Auto CPAP device combines high performance with comfort and ease of use in one of the smallest overall footprints available.

The Sandman Auto Humid Control humidification system provides precise levels of humidification by continually measuring the voltage and current delivered to the heater. This allows for a constant differential between water and air temperature to minimize tubing condensation, and gives patients a stable humidification level throughout the night for highly effective and comfortable therapy.
