title: An anaesthetic scavenging system for paediatric and adult use.
abstract: A scavening dish is described which removes large volumes of contaminated air. It can be placed close to the open-tailed bag of the paediatric T piece to provide a safe, convenient and efficient scavenger without any modification of the patient circuit. Measurements before and after installation have shown it to be capable of reducing nitrous oxide levels in the operating theatre to between 40 and 0 parts per million. The dish has been incoporated into a scavening system which can also be used with a standard antipollution valve or ventilator exhaust port.
