Operating the Scavenger Interface for Passive Systems
In a typical anesthesia circle system, waste gas exits from 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. Hose connections are shown in
Figure 8-2.
WARNING: The positive pressure relief valve must be inspected and
cleaned (if necessary) at six month intervals.
