A humidifier system for neonatology that functions according to the 'membrane humidification' principle was subjected to a performance test in our laboratory. Humidification and heating of the respiratory gases took place in a module consisting of a net of hollow fibres placed inside the incubator. In 18 measurement combinations flow, respiratory gas temperature, and incubator temperature were varied. At respiratory gas temperatures within the range of 33-37 degrees C the minimum international standard for the absolute air humidity in the respiratory gas was achieved or exceeded in all measurements. No controlled clinical tests regarding the importance and long term effects of different temperatures and different humidity levels in the inspiratory air are yet available for the ventilation treatment of neonates.
一种按照“膜加湿”原理运行的新生儿科加湿器系统在我们实验室进行了性能测试。呼吸气体的加湿和加热在一个由置于培养箱内的中空纤维网组成的模块中进行。在18种测量组合中，对流量、呼吸气体温度和培养箱温度进行了变化。在呼吸气体温度为33 - 37摄氏度的范围内，所有测量中均达到或超过了呼吸气体中绝对空气湿度的最低国际标准。关于吸气空气中不同温度和不同湿度水平对新生儿通气治疗的重要性及长期影响，目前尚无对照临床试验。
