Two hundred and thirty one patients awaiting elective surgery were divided on the basis of spirometric examination into normal (group A) and those with increased airway resistance (group B). The mean arterial oxygen tension for the 151 normal subjects was 96·3 (± 11·6) mm. Hg. There was a significant inverse correlation of Pao with age and dynamic lung volumes. The 80 patients in group B were significantly older and their mean Pao was 88·7 (± 12·9) mm. Hg. There was, however, no correlation between Pao and age in this group, probably because the increased airway resistance had a greater influence in lowering the arterial oxygen tension than did the age factor alone.
231名等待择期手术的患者根据肺活量测定检查结果分为正常组（A组）和气道阻力增加组（B组）。151名正常受试者的平均动脉血氧分压为96.3（±11.6）毫米汞柱。动脉血氧分压与年龄和动态肺容量呈显著负相关。B组的80名患者年龄明显较大，他们的平均动脉血氧分压为88.7（±12.9）毫米汞柱。然而，该组中动脉血氧分压与年龄之间没有相关性，可能是因为气道阻力增加对降低动脉血氧分压的影响比年龄因素单独作用更大。
