oximeter
noun [ C ] medical specialized uk/ɒkˈsɪm.ɪ.tər/ us/ɑːkˈsɪm.ə.t̬ɚ/ (also pulse oximeter)
血氧计
a device, usually attached to the end of a person's finger, used to measure the level of oxygen in their blood
Since the oximeter amplifies the pulse signal, it will pick up a complete loss of a pulse, but not significant decreases. 因为血氧计会将脉搏信号放大，它能检测到失去脉搏，但无法检测到脉搏的明显减弱。
