1 Introduction
1.2 Function
1.2.1 WM 100 TD therapy devices
The fan in the therapy device sucks ambient air in through a filter,
compresses it, and routes it to the device outlet.
From here, the air flows through the hose system and the mask to
the patient. The exhalation system in front of the mask or
optionally integrated in the mask prevents CO
2
-enriched exhaled
air from collecting in the hose system.
The therapy device determines and analyzes the pressure and
breathing flow signal. This allows respiratory events to be
recognized.
The device can function with one pressure level (CPAP) or with two
or three pressure levels (BiLevel or inspiratory pressure, expiratory
pressure, and end-expiratory pressure). Depending on the version
employed, the pressure levels can be set automatically by the
device within preset limits, or they can be set manually. Depending
on the mode, the pressure can be continually applied at one level,
or triggered by the patient, or applied with time controls. Pressure
signals, breathing flow signals, and respiratory events can be saved
and/or emitted as an analog output on a PSG system.
The therapy data are saved in the device and on an SD card for the
therapy control.
The device is operated via an On/Off button and a touchscreen.
The device can be remotely controlled using the prismaTS therapy
software.
In the case of a power failure, the settings are retained and the
therapy is continued once the power supply is restored.
