The Sandman Duo Bi-level device was designed with your patients in mind to help them comply with their therapy comfortably and consistently. The Sandman Duo device's Adaptive Pressure Stability means the device responds quickly and accurately to your demands throughout the night, to greatly reduce common pressure spikes and drops during the breathing cycle. It also employs our unique Humid Control+ which provides consistent humidification levels for increased sleeping comfort. This is just another example of our committed focus to work together to improve compliance.

At Covidien, we realize that the interface is a very personal decision and can be the key to continuing therapy. We also realize the patient can receive large pressure variances depending on the combination of interface and device. The Sandman Duo device compensates for this variance with True Circuit Calibration and accurately delivers the prescribed pressure to virtually any interface and tubing combination at the end of the circuit, where accuracy counts.

Since all patients are not alike, they require individual adjustment to meet their therapy needs. As an answer to this, the Sandman Duo and Duo ST devices are equipped with Rise Time adjustment and our patented FlowSens technology, which allows for Inspiratory and Expiratory Sensitivity adjustments to meet this challenge. With clinician support, the devices can be adjusted to match the patient’s ventilatory needs even in the presence of potential unwanted leaks.
