Each of four examiners performed standardized physical examinations on a group of patients who had just undergone tests of ventilatory function. The intensity of breath sounds heard with deep inspiration was graded on a rating scale of 0 to 4; the grades in six areas of the chest were added to give a total score, with possible values ranging from 0 to 24. Correlation of breath-sound scores with percentage of predicted forced expiratory volume in one second (FEV1) was significant at the 1 percent level for all of the examiners. Differences between the examiners in their assessment of breath sounds were not statistically significant. Grading the loudness of breath sounds was a poor screening test for mild ventilatory abnormality, but normal breath sounds nearly excluded the possibility of severe reduction in the FEV1. Definitely reduced breath-sound intensity was strong evidence for the presence of obstructive pulmonary disease.
四位检查者分别对一组刚接受过通气功能测试的患者进行了标准化体格检查。深吸气时听到的呼吸音强度按0至4的评分量表进行分级；胸部六个区域的分级相加得出总分，可能值范围为0至24。所有检查者的呼吸音评分与预计一秒用力呼气量（FEV1）百分比之间的相关性在1%水平上具有显著性。检查者在呼吸音评估方面的差异无统计学意义。对呼吸音响度进行分级对轻度通气异常而言是一种较差的筛查测试，但正常呼吸音几乎排除了FEV1严重降低的可能性。呼吸音强度明显降低是存在阻塞性肺病的有力证据。
