Pulse oximetry represents a major advance in patient monitoring, but measurement below 70 to 80% saturation has important limitations. Several authors have tested pulse oximetry at low saturations with conflicting results. A review of these data indicates that every patient with a pulse oximeter value below 75 to 80% SaO2 should have one or more invasive measurements of the arterial SaO2 in order to avoid undetected severe hypoxemia.
脉搏血氧饱和度测定是患者监测方面的一项重大进展，但饱和度低于70%至80%时的测量存在重要局限性。几位作者在低饱和度情况下测试了脉搏血氧饱和度测定，结果相互矛盾。对这些数据的综述表明，每个脉搏血氧仪值低于75%至80% SaO2的患者都应进行一次或多次动脉SaO2的有创测量，以避免未被发现的严重低氧血症。
