Overview
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
"7.4 Checking patient hose system" on page 50).
The symbol indicates the correct position for
insertion of the lip membrane.
When connecting the patient valve, take care to
ensure that the direction of respiratory gas flow is
correct (see arrows).
