Capacity resistance breaking and volume resistance breaking were determined in normal subjects divided into three groups according to their age. There was a statistically significant age dependence with regard to both values. At a higher age, capacity resistance breaking increases in the respiratory tract already above the end-expiratory intrathoracic gas volume. There is a clear-cut age-dependent narrowing of the ventilatory reserve. This points to a relationship to "senile emphysema". It is probable that the premature loss of individual bronchi is a factor in the abnormal clearing mechanism of the elderly lung.
根据年龄将正常受试者分为三组，测定了顺应性阻力破坏和容积阻力破坏。这两个值在统计学上均有显著的年龄依赖性。在较高年龄时，顺应性阻力破坏在已经高于呼气末胸腔内气体容积的呼吸道中增加。通气储备存在明显的年龄依赖性变窄。这表明与“老年性肺气肿”有关。个别支气管的过早丧失可能是老年肺异常清除机制的一个因素。
