Abstract
Values of arterial oxygen saturation were estimated using an ear oximeter while subjects breathed a mixture of 15% oxygen in nitrogen. Results obtained from patients with lung disease were clearly separated from results obtained from normal subjects, and the lowereing of saturation was related to the clinical severity of the disease. Patients with low oximeter readings with 15% oxygen also had low levels of arterial oxygen tension during exercise.
摘要
当受试者呼吸氮气中含15%氧气的混合气体时，使用耳部血氧计估算动脉血氧饱和度值。从肺部疾病患者获得的结果与正常受试者获得的结果明显分开，饱和度的降低与疾病的临床严重程度相关。使用15%氧气时血氧计读数低的患者在运动期间动脉血氧分压水平也低。
