VITAL CAPACITY, MAXIMUM BREATHING CAPACITY AND MAXIMUM BREATHING RATE IN HEALTHY MALE ADULTS

Abstract

The vital cabacity and the maximum breathing capacity have been studied in 1, 169 healthy individuals of different ages from 20 to 80 years in connection with an interest in the air velocity index.
The results show that the values of vital capacity, maximum breathing capacity and maximum breathing rate per square meter of body surface are, to some extent, decreased in accordance with the advent of age, although the maximum breathing rate appears most suitable to evaluate a failure in the ventilatory function associated with emphysema or silicosis.
