Heat and moisture exchangers (HME) are commonly used during general anaesthesia and intensive care of patients on mechanical ventilators. Some of the HME manufacturers provide HMEs with a Luer lock fitting for connecting side stream CO(2) monitoring line, Luer lock cap, and a non-threaded cap mount. However, HMEs from different manufacturers and HMEs meant for use in children and for adults from the same manufacturer vary in the presence/absence of non-threaded cap mount. This can create confusion to the clinicians and can result in inadvertent connection of the CO(2) monitoring line to the non-threaded cap mount resulting in blocked CO(2) monitoring line and leak in the circuit. We caution all the anaesthesiologists and intensivists regarding this possibility while using HMEs from different manufacturers.
热湿交换器（HME）常用于机械通气患者的全身麻醉和重症监护期间。一些HME制造商提供带有鲁尔锁接头的HME，用于连接旁流式二氧化碳监测线、鲁尔锁帽和无螺纹帽座。然而，不同制造商生产的HME以及同一制造商生产的适用于儿童和成人的HME在有无无螺纹帽座方面存在差异。这可能会给临床医生带来困惑，并可能导致二氧化碳监测线意外连接到无螺纹帽座，从而导致二氧化碳监测线堵塞和回路泄漏。我们提醒所有麻醉医生和重症监护医生，在使用不同制造商生产的HME时要注意这种可能性。
