We describe a case where the expiratory bacterial filter was completely blocked by a plastic membrane. Significantly increased airway pressures and inability to deliver adequate tidal volume to the patient were experienced. The cause of machine failure could not be identified until a complete preanesthesia machine manual check was performed. All machines and circuits should be checked manually, even with the availability of new and advanced self-tests in machines. Backup ventilation equipments and familiarity with signs of expiratory and inspiratory limb obstruction should not be underestimated.
我们描述了一个呼气细菌过滤器被塑料膜完全堵塞的病例。出现了气道压力显著升高以及无法为患者输送足够潮气量的情况。在对麻醉机进行全面的术前手动检查之前，无法确定机器故障的原因。即使机器具备新的先进自检功能，所有机器和回路都应进行手动检查。备用通气设备以及对呼气和吸气支路阻塞迹象的熟悉程度都不应被低估。
