Abstract
Thirty-five asthmatic patients (average age 28 years) who attended a pulmonary function laboratory when their mean ratio of forced expiratory volume in one second: forced vital capacity was 81 per cent (within the normal range for their age group) had arterial hypoxaemia and hypocapnia. These were probably secondary to lung hyperinflation and pulmonary ventilation/perfusion imbalance. The pulmonary abnormalities of bronchial asthma are not always detected by simple spirometric tests and the results of such tests should be interpreted cautiously.
摘要
35名哮喘患者（平均年龄28岁）前往肺功能实验室就诊，当时他们的一秒用力呼气量与用力肺活量的平均比值为81%（在其年龄组的正常范围内），但存在动脉低氧血症和低碳酸血症。这些可能继发于肺过度充气和肺通气/灌注失衡。支气管哮喘的肺部异常并不总是能通过简单的肺量计测试检测出来，对此类测试结果的解读应谨慎。
