Dräger Narkomed 2B - Operating the Scavenger Interface for Non-Active Systems

Section 5 - Operation
Scavenger Interface for Passive Systems
Operating the
Scavenger Interface
for Non-active
Systems
In a typical anesthesia circle system, waste gas exits form the breathing
system APL or ventilator relief valves and passes through the scavenger
to the exhaust system. If the hospital exhaust system stopped
functioning (or if the path between the scavenger and the exhaust
system becomes blocked), positive pressure would build up within the
scavenging and breathing systems. To prevent such a harmful pressure
build-up, the scavenger’s positive pressure relief valve is set to open at a
pressure of 5 cm H
2
O. Waste gas then exits through the holes in the
relief valve housing. Therefore, you do not have to adjust this scavenger.
You must, however, make sure that hoses are properly connected and
that the positive pressure safety relief valve is functioning.
WARNING: The positive pressure relief valve must be inspected and
cleaned (if necessary) at six month intervals.
