Respiratory pressures and function in young adults.

摘要: The relationships of lung functions to maximal respiratory pressures relative the role other recognized determinants (height, weight, age, and smoking status) were examined in 924 healthy Caucasian urban residents, 369 males 15 35 yr age 555 females 13 age. In subjects no longer thought be growing stature, height was main determinant most functions. After height, forced vital capacity (FVC), expiratory volume one second (FEV1), peak flow men women, with weight also an important women. Age had consistent effect, and, although smokers lower than nonsmokers for several tests, effects only significant FEV1 during middle half FVC These findings indicate that, if required, between-subject variation this group can reduced by taking into account relatively simple measurement ins...
