Sandman Duo ST BiLevel CPAP Machine with Built In Heated Humidifier

The Sandman Duo ST is lightweight, compact and user-friendly. The Duo ST BiLevel features an intelligent pressure stability and respiratory events detection system that reacts to an obstruction event. Also, the Sandman Series includes the humidifier technology called Humid Control. The built in humidifier actually measures the temperature outside the chamber and adjusts the heater plate to minimize condensation. At 2.64 pounds, take the Sandman Duo anywhere and feel confident you will receive effective therapy.


Product Features

The Sandman Duo ST BiLevel machine is designed to provide accurate therapy pressure using an advanced Adaptive Pressure Stability system that helps in detecting respiratory events. The Duo ST is equipped with pressure and flow sensors that detect apneas, hypopneas, inspiratory flow limitations and snoring. Once an event occurs, the machine reacts using an enhanced algorithm that smoothly adjusts the pressure during events.

The Duo ST allows BiLevel users to set a backup frequency, I/E ratio and pressure rise time. Use the I/E ratio to set the time between inhalation and exhalation. As an alternative, set the Duo ST to CPAP mode and turn on Pressure Alter feature which allows users to adjust their pressure up or down 1cmH20 without going into Clinical Mode.

The Sandman Series uses Covidien’s unique Adaptive Pressure Stability (APS) technology that limits the peak to peak variations of CPAP pressure when a user breathes. Adaptive Pressure Stability responds quickly and accurately to several common conditions that result in changes from your prescribed pressure down to each breath.
