[Behm's T-piece for reducing anesthesia gas pollution at the anesthesia work site].

The safety standards demanded for performing anaesthesia and the increasing burden of work to be handled by OP personnel entail continuous supervision and elimination of hazards and leaks. One example illustrates this necessity: Anaesthetic agents in the circular system of the induction are pollute the atmosphere after disconnection of one patient and transport into the OP suite and are a potential risk to personnel and next patient. C. Behm developed a T-piece which connects the Y-piece with the scavenging system leading to elimination of residual anaesthetics from the circular system. A useful byproduct is the longer life of the galvanic O2 sensor.
