The failure of anaesthetic equipment as a result of maintenance is extremely rare. The ingress of water into the flowmeters of an anaesthetic machine from the piped medical air supply is reported and is possibly unique. The piped medical air supply was open to the atmosphere during maintenance. Water condensed in the gas pipeline and this was not noticed during subsequent testing. Water was seen leaking from the orthopaedic air tools used for surgery but was assumed to be from the autoclaving process. Later the same day, when medical air from the piped source was used as part of the gas mixture for a general anaesthetic, water was seen filling the barrel of the flowmeter air control valve. This could have had far-reaching and dangerous consequences for the patient, which were fortunately averted.
因维护导致麻醉设备故障的情况极为罕见。据报道，管道式医用空气供应中的水进入了麻醉机的流量计，这可能是独一无二的情况。在维护期间，管道式医用空气供应与大气相通。水在气体管道中凝结，而在随后的测试中并未被发现。有人看到用于手术的骨科气动工具漏水，但当时认为是来自高压灭菌过程。当天晚些时候，当来自管道气源的医用空气被用作全身麻醉气体混合物的一部分时，发现水充满了流量计空气控制阀的筒体。这原本可能给患者带来深远且危险的后果，所幸得以避免。
