[Normal values for vital capacity and forced expiratory capacity of the lungs in old age].
In 545 healthy men aged 71-90 years and 160 women aged 71-85 years, vital capacity and FEV1.0 in the standing position were measured using a closed spirometer system. Analysis of the results from different groups based on age and body size makes it possible to extend an already existing nomogram for prediction of normal values for vital capacity up to 90 years in men and up to 80 years in women. There is no linear relationship between age and vital capacity in men and women aged 20-90 years. The average FEV1.0 is more than 70% of the effective vital capacity in men and women aged 71-90 and 71-85 years respectively. A reduction of more than 20% in vital capacity, and a FEV1.0 below 65% of the actual vital capacity, is to be considered pathological in men and women of any age.
