Abstract

A critical analysis of the arterial/alveolar oxygen tension ratio (a/APO2) is presented by rearranging the terms of the pulmonary shunt equation. The influence of the shunt and inspired oxygen concentration on a/APO2 are illustrated. It is shown that, despite reports to the contrary, a/APO2 varies with F1O2, particularly at high shunt levels.

摘要

通过重新排列肺分流方程的各项，对动脉/肺泡氧分压比（a/APO2）进行了批判性分析。阐述了分流和吸入氧浓度对a/APO2的影响。结果表明，尽管有相反的报道，但a/APO2随F1O2而变化，尤其是在高分流水平时。
