Functional Description Cpap 20E - Weinmann Homecare CPAP 20e Manual

1.3 Functional description CPAP 20e

CPAP 20e operates according to the principle of an electrically driven flow generator, with
the pressure level being controlled electronically.
• A fan draws in ambient air via a filter and conveys it to the unit outlet.
From here the air flows through the breathing hose and the mask to the
patient.
• A pressure sensor measures the upcoming pressure at the unit outlet and
shows this on the display. The microprocessor-controlled flow generator
controls the pressure to the set value and reduces fluctuations in pressure
caused by breathing.
• A softstart automatic system is installed to help the patient fall asleep
more easily. When the unit is switched on, the CPAP pressure starts at
the initial pressure selected by the doctor and is then slowly increased to
the setpoint pressure selected. The time of the pressure increase can be
adjusted between 5 and 30 minutes in 5-minute increments.
• The therapy parameters are adjusted using the SOMNOadjust remote
control system or the SOMNOsupport evaluation program.
• CPAP 20e automatically saves all settings in the event of a power failure.
This means that the unit does not need to be reset when power is
restored.
1.4 Functional description CLICK 2
The humidifier works on the so-called overflow principle. The air coming from the therapy
unit is conveyed across the surface of a heated water tank, increasing the relative humidity
and the temperature of the air flow. The amount of humidity released can be adjusted us-
ing the buttons on the Weinmann therapy unit. The output of the heater rods and conse-
quently the temperature of the water in the humidifier chamber is controlled electronically
by the Weinmann unit.
The water level can be checked at any time through the window in the humidifier chamber.
