Pulmonary function study in old age.
A study was carried out in 100 patients aged between 70 and 90 years to investigate pathological and respiratory function changes in old age. Vitalograph and peak flow meter measurements were made, but blood gas analysis was only carried out in 6 patients in view of the technical difficulties. Analysis of the results showed that there was a definite, moderate, restrictive type of defect in pulmonary function in almost all the patients, in those with generalized senile changes as well as in those with a pathological condition. Blood gas analysis showed a minimum degree of alteration in oxygen tension and saturation with normal carbon dioxide tension.
