最大静态吸气口压和呼气口压（分别为PI，mns和PE，max）能够无创地测量整体呼吸肌强度。本研究的目的主要是获得成年中国人、马来人和印度人的PI，max和PE，max的正常值，其次是研究它们对这些受试者的肺容量的影响。（221名中国人，111名马来人，120名印度人）被招募。PI、最大残气量（RV）、PE、最大肺容量（TLC）和用力肺活量（FVC）均在坐位测量，男性PI、最大残气量和PE、最大残气量以及男性和女性FVC均存在明显的种族差异，中国男性PI、最大残气量和PE、最大残气量以及男性和女性FVC均高于中国男性，最大值（平均值（+/-SD）88.7+/-32.5 cmH（2）O）和PE，最大值（113.4+/-41.5）高于马来男性（PI，最大值74.0+/-22.7 cmH（2）O，PE，最大值94.7+/-23.4 cmH（2）O）。中国男性的PE，max高于印度男性（PI，max = 83.7+/-30.0 cmH（2）O，PE，max 98.4+/-29.2 cmH（2）O）。中国女性之间无显著差异（PI，max 53.6+/-20.3 cmH（2）O，PE，max 68.3+/-24.0 cmH（2）O）。马来女性（PI，最大50.7+/-18.3 cmH（2）O，PE，最大63.6+/-21.6 cmH（2）O）和印度女性（PI，最大50.0+/-15.2 cmH（2）O，PE，最大60.7+/-20.4 cmH（2）O）。在两种性别中，中国人的FVC均高于马来人和印度人。在调整了年龄、身高和体重后，种族仍然是男性PE，max和两种性别FVC的决定因素。在两种性别中，FVC仅与PI，max和PE，max弱相关。亚洲人的呼吸肌力和肺容量存在种族差异，然而，呼吸肌强度不能解释健康亚洲受试者肺容量的差异。
Maximal static inspiratory and expiratory mouth pressures (PI,mns and PE,max, respectively) enable the noninvasive measurement of global respiratory muscle strength, The aim of this study was primarily to obtain normal values of PI,max and PE,max for adult Chinese, Malays and Indians and, secondarily, to study their effect on lung volumes in these subjects.Four hundred and fifty two healthy subjects (221 Chinese, 111 Malays, 120 Indians) were recruited. Measurements of PI,max from residual volume (RV), PE,max from total lung capacity (TLC) and forced vital capacity (FVC) mere obtained in the seated position.There mere significant ethnic differences in PI,max and PE,max measurements obtained in males, and FVC measurements in both males and females, Chinese males had higher PI,max values (mean (+/-SD) 88.7+/-32.5 cmH(2)O) and higher PE,max values (113.4+/-41.5) than Malay males (PI,max 74.0+/-22.7 cmH(2)O, PE,max 94.7+/-23.4 cmH(2)O). Chinese males had higher PE,max than Indian males (PI,max = 83.7+/-30.0 cmH(2)O, PE,max 98.4+/-29.2 cmH(2)O). There were no significant differences among Chinese females (PI,max 53.6+/-20.3 cmH(2)O, PE,max 68.3+/-24.0 cmH(2)O). Malay females (PI,max 50.7+/-18.3 cmH(2)O, PE,max 63.6+/-21.6 cmH(2)O) and Indian females (PI,max 50.0+/-15.2 cmH(2)O, PE,max 60.7+/-20.4 cmH(2)O). In both sexes, the Chinese had a higher FVC compared with Malays and Indians, After adjusting for age, height and weight, race was still a determinant for PE,max in males, and FVC in both sexes, The FVC only correlated weakly with PI,max and PE,max in both sexes.Ethnic differences in respiratory muscle strength, and lung volumes, occur among Asians, However, respiratory muscle strength does not explain the differences in lung volumes in healthy Asian subjects.
