Abstract: To evaluate the elastic properties of the lungs by static pressure-volume curve, static lung compliance, maximal static recoil pressure and coefficient of retraction were measured using esophageal-balloon technique in 20 normal control subjects (10 young and 10 aged men) and 14 male patients with pulmonary emphysema that were diagnosed with clinical findings and pulmonary function tests. The results were as foliows: 1) Static lung compliance was significantly increased in emphysema group as compared with young and aged control group (P 0. 1). 2) Maximal static recoil pressure was significantly decreased in emphysema group as compared with young and aged control group (P<0.001) and that in aged control group was significantly lower than in young control group (P<0.01). 3) Coefficient of retraction was significantly decreased in emphysema group as compared with young and aged control group (P<0.001) and that in aged control group was significantly lower than in young control group (P<0.025), In conclusion, the elastic recoil pressure of the lung in aged control group was lower than that in young control group. In pulmonary emphysema patients, it was comfirmed that there was increased distensibility and decreased elastic recoil pressure of the lung. Therefore, if was thought that measurement of elastic properties of the lung will be helpful for the clinical diagnosis, understanding of the elasticity of the lung and ventilatory mechanics in pulmonary emphysema.
