The device is intended for respiration therapy in adults. It generates two pressure levels in the S-, ST- or T–mode via an electrically controlled turbine. Switching from one pressure level to another is realized via a quick change of the revolutions of the fitted high-performance blower to keep the stress for the patient as low as possible.

S-Mode

Spontaneous trigger – the change from one pressure level to another is triggered by starting respiration of the patient only. A decline in pressure to the set lower pressure level also occurs once the inspiration flow ends.

ST-Mode

Spontaneous breathing and Time – as long as the patient is breathing independently the device is operating in the S-mode. Once the patient stops breathing the device automatically switches into the T-mode and provides respiration for the patient in the prescribed safety frequency. The delay time after which the device switches into the T-mode can be set.

T-Mode

Time respiration with prescribed, set inspiration time. If the trigger function is deactivated the patient is ventilated according to the set parameters. If the trigger function is activated the device accepts only spontaneous trigger signals in the expiration phase.

Trigger device

The respiration trigger detects the patients efforts to breath in and out and signals these efforts to the control device. A flow-based trigger is integrated which can be set separately for inspiration and expiration. In connection with an optimum flank adjustment this results in a ventilation which is very comfortable for the patient and which gives the patient the impression as if the device is following the natural respiration without delay.

To generate the necessary pressure, the device is provided with an electronically controlled blower. In order to keep the stress for the patient as low as possible, the blower has been designed with a high reserve capacity and a quick control response. The pressure is measured directly in the mask and constantly controlled by the device. Consequently, the breathing work for the patient is as easy as possible. There are two separate tubings in the device.

In addition to the mask alarm, the device offers another safety function, the power failure alarm. It automatically restarts the motor after power restoration. For added comfort an alarm clock is integrated in the device. Further comfort functions include a soft start ramp, the automatic start-stop function and the adjustable display brightness.
