title: [Dynamic lung volume in the aged and in obstructive ventilatory insufficiency].
abstract: Mid-expiratory maximum flow, maximum expiratory flow rate and maximum expiratory volume per sec. were studied in 66 males aged 42 to 88 yr., including 27 normal subjects and 39 with obstructive respiratory insufficiency to determine the importance and significance of these parameters in the evaluation of dynamic resistance to flow and in the study of the senile lung.
