The predictive value of pulse oximetry was evaluated in 100 patients who attended the emergency department with acute asthma. Oximetry after treatment with a cut off point of less than 91% had a sensitivity of 42% and specificity of 78% for unfavourable outcome, and oximetry before treatment had a sensitivity of 36% and a specificity of 57%. Despite its low sensitivity, oximetry after treatment does seem to have a role in minimising diagnostic errors in the emergency department, but only when used in conjunction with clinical assessment.
对100名因急性哮喘到急诊科就诊的患者评估了脉搏血氧饱和度测定法的预测价值。治疗后血氧饱和度测定，以低于91% 为临界值，对不良结局的敏感性为42%，特异性为78%，而治疗前血氧饱和度测定的敏感性为36%，特异性为57%。尽管治疗后血氧饱和度测定法敏感性较低，但在急诊科尽量减少诊断错误方面似乎确实有作用，但前提是要与临床评估结合使用。
