Static compliance in subjects with intact lungs.

The static compliance was determined in 55 subjects with healthy lungs. Average values are within 2.696 liters/kPa (age between 20 and 30 years) and 1.794 liters/kPa (age between 71 and 80 years). Static compliance was shown to be exclusively related to age (p less than 0.001). Broca index, sex, cigarette smoking and intrathoracic gas volume did not influence static compliance. The relation can best be described by a logarithmic regression equation.
