Peak expiratory flow rates were measured in 124 normal elderly men (55-85 yr) using the Wright's peak flow meter. In the less than 60 yrs age group (n = 32; mean age 57.7 yr) the PEFR was 431 +/- 13 lpm, while for the group greater than 60 yr (mean age 69.0 +/- 6.0; n = 92), the PEFR value was 373 +/- 11 1pm. These values are similar to those reported in other Indian studies, suggesting that the ethnic variations amongst Indian subjects do not affect the PEFR. However, the reported values are lower than those observed in Europeans, but greater than those of Chinese. The PEFR regressed at a rate of 4.47 1pm/year increase in age, but is positively correlated to the subjects' height (cm), and their FVC and FEVI. The smokers had a significantly higher PEFR as compared with the non-smokers. This finding was contrary to what was expected.
使用赖特峰流速仪对124名正常老年男性（55 - 85岁）进行了呼气峰值流速测量。在年龄小于60岁的组（n = 32；平均年龄57.7岁）中，呼气峰值流速为431±13升/分钟，而在年龄大于60岁的组（平均年龄69.0±6.0；n = 92）中，呼气峰值流速值为373±11升/分钟。这些值与其他印度研究报告的值相似，表明印度受试者之间的种族差异不会影响呼气峰值流速。然而，报告的值低于欧洲人观察到的值，但高于中国人的。呼气峰值流速随年龄增长以每年4.47升/分钟的速度下降，但与受试者的身高（厘米）、用力肺活量和第一秒用力呼气量呈正相关。吸烟者的呼气峰值流速明显高于非吸烟者。这一发现与预期相反。
