Assembly and preparation
4.6.2 Passive anesthetic gas scavenging
With passive anesthetic gas scavenging, the anesthetic gas is only transported by
overpressure in the breathing system. The anesthetic gas can be routed out of the
room via a connected scavenging hose.
● Make sure that the ventilation slots on the underside of the receiving system are
not blocked.
WARNING
Risk of negative pressure
If a passive receiving system is connected to an active scavenging system, a
negative pressure may arise in the patient’s lungs.
► Connecting a passive receiving system to an active scavenging system is not
permitted.
WARNING
Risk of overpressure
If the relief valve in the passive receiving system or the scavenging hose is blocked,
overpressure will occur in the breathing circuit and in the patient’s lungs.
► Only connect the passive receiving system using kink-proof and pressure-tight
scavenging hoses.
► Take care that the scavenging hose does not become blocked.
► Perform a visual inspection of the relief valve for damage and soiling.
WARNING
Risk of ambient air contamination
The ambient air will be contaminated if the passive receiving system feeds excess
anesthetic gas to a ventilation system with circulating air.
► Use the passive receiving system only with ventilation systems that work without
circulating air.
1. Connect the scavenging hose (1) to the nozzle on the receiving system. If an
external anesthetic gas monitor is used, connect the sample gas outlet of the
monitor with port (2) using the supplied hose connector.
