Pulmonary Compliance in Patients with Periodic Breathing

Abstract
A study of pulmonary compliance in patients with periodic breathing was made. The elastic properties of the lung were found to be normal in some patients and grossly decreased in others. Two types of periodic breathing mechanics were found: in one there are similar variations of tidal volumes and unchanged pulmonary compliance; in the other a constant fluctuation of the intraesophageal pressure associated with the variations in tidal volume.
