Routine checking of the FIO2 of a mixture delivered by a ventilator revealed large discrepancies between the FIO2 assigned and that effectively delivered, the latter being low. Measurements of FIO2 at the wall outlets showed the O2 delivery pipeline to be contaminated by compressed air. By disconnecting all the ventilators supplied by this pipeline one after the other, one ventilator, or rather its blender, was found responsible.
对呼吸机输送的混合气的吸入氧浓度（FIO2）进行常规检查时发现，设定的FIO2与实际输送的FIO2之间存在很大差异，实际输送的FIO2较低。对壁式出口处的FIO2测量显示，氧气输送管道被压缩空气污染。通过逐个断开由该管道供气的所有呼吸机，发现有一台呼吸机，确切地说是其混合器，是造成这一问题的原因。
