The Dreamstar™ Duo, Dreamstar™ DuoST (and their equivalents in the Evolve configuration) are intended for the non-invasive ventilation of patients weighing over 30 kg (66 lbs), suffering from respiratory failure or Sleep Apnoea Syndrome (SAS), but who are not dependent on ventilatory assistance. These devices can be used at home or in a sleep center.

DreamStar Duo
The FlowSens algorithm automatically adjusts the trigger thresholds and allows the machine to instantly respond to changes in the patient’s ventilatory demand. It also detects and compensates leaks avoiding auto-triggering of the device. The Water Control and Humid Control” features control the humidifier output and minimize condensation in the patient circuit.
DreamStar Duo ST
In addition to the features and functions of DreamStar Duo, DreamStar Duo ST offers the setting of a backup frequency an I / E ratio and rise time. Using the ADAPT screen, the physician can view the treatment parameters in real-time (tidal volume, breathing frequency, average leak, inspiratory time, pressures) and act instantly when settings need changing.
