Using the ventilator

position marked by the white triangle, or by switch-
ing off the ventilator.

If audio response is activated, the ventilator confirms 
the return to ventilation mode by announcing: 
“Mask ventilation mode. Tilt back head, secure mask 
tightly” (from serial number 8000 and following re-
pair/servicing/firmware update: “Ventilation pres-
sure limit 20 mbar”).

6.8  Terminating ventilation or Demandflow 

Important

Never empty the oxygen 
cylinder completely. Re-
turn the cylinder for filling 
while it still contains resid-
ual pressure. This prevents 
entry of moist atmospheric 
air that can cause 
corrosion.

1. Check the oxygen supply on the pressure reduc-

er gauge. Always change the cylinder in good 
time, e.g. when the pressure is lower than 
50 bar, to ensure that oxygen is available for an 
adequate period. 

2. Close the valve of the oxygen cylinder.

3. Switch off the MEDUMAT Easy. To prevent the 

ventilator being switched off unintentionally, ON/
OFF switch must be kept pressed down for at least 
2 seconds until the LEDs in the alarm panel 

3

 light 

up. If audio response is enabled, the ventilator an-
nounces: “Close oxygen cylinder”.
