1.2 Special symbols on the ventilator
Patient valve
The symbol on the patient valve is a reminder
that the lip membrane must be changed immediate-
ly if it becomes crinkled, sticky or misshapen. The pa-
tient must not be used again until the membrane has
been changed, as this could cause malfunction (see
“8.3 Checking patient hose system” on page 48).
The symbol indicates the correct position for
insertion of the lip membrane.
When connecting the patient valve, take care to en-
sure that the direction of respiratory gas flow is cor-
rect (see arrows).

3. Description
3.1 Intended use
MEDUMAT Easy is an automatic oxygen respiration
device (short-term ventilator) with additional inhala-
tion facility.
You can use MEDUMAT Easy:
• to revive patients at the site of the emergency;
• for longer periods in more protracted
emergencies;
•for short-term O
2 inhalation using a respiration
mask.
You can use MEDUMAT Easy while transporting
patients:
• between the various rooms and departments of
a hospital;
• between the hospital and other premises;
• in emergencies;
• when transport over considerable distances is
planned.
MEDUMAT Easy:
• is designed to provide controlled ventilation to
persons of 10 kg body weight or more;
• is used to treat respiratory arrest;
•can be preset to parameters that ensure evenly
balanced ventilation, provided that the selected
maximum ventilation pressure Pmax is not
exceeded.
