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).
