Measurements of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC ratio, functional residual capacity (FRC), total lung capacity (TLC), residual volume (RV), and RV/TLC ratio have been made in 331 normal Cantonese subjects (134 male and 197 female). The results have been expressed in multiple regression equations relating the volumes to age, height, and weight and have been compared with those of other workers. Lung volumes obtained in this study are in general lower for Chinese subjects than those reported for Caucasians. Similar findings for FVC were reported by Chuan and Chia (1969) in Singapore and by Wu and Yang (1962) in Taiwan. Significant differences, however, are noted for FRC, TLC, RV, and RV/TLC between our findings and those of Chuan and Chia. Our series is unbalanced because of an uneven distribution of age groups. In fact in none of the reported studies on Chinese subjects, including that of da Costa (1971), is the series large or balanced. Clearly, further research is required in this ethnic group to get more reliable predictive formulae for lung volumes.
对331名正常粤语人群（134名男性和197名女性）进行了用力肺活量（FVC）、一秒用力呼气量（FEV1）、FEV1/FVC比值、功能残气量（FRC）、肺总量（TLC）、残气量（RV）以及RV/TLC比值的测量。结果已用将这些容积与年龄、身高和体重相关联的多元回归方程表示，并与其他研究人员的结果进行了比较。本研究中获得的中国受试者的肺容积总体上低于报道的高加索人的肺容积。Chuan和Chia（1969年）在新加坡以及Wu和Yang（1962年）在台湾报道了关于FVC的类似发现。然而，我们的研究结果与Chuan和Chia的研究结果在FRC、TLC、RV和RV/TLC方面存在显著差异。由于年龄组分布不均衡，我们的系列研究存在不平衡性。事实上，在所有已报道的关于中国受试者的研究中，包括da Costa（1971年）的研究，样本量都不大或不均衡。显然，需要对这个种族群体进行进一步研究，以获得更可靠的肺容积预测公式。
