Abstract

A number of studies have described disorders in pulmonary function related to the degree of hemodynamic perturbations. The forced oscillations method is a sensitive tool to appreciate changes in the acoustic characteristics of the lung. An apparatus has been developed for use in an intensive care unit (ICU). A band-limited (1-50Hz) forced random noise is applied to the mouth of the patient. The acoustic impedance data (magnitude and phase) are interpreted in terms of a second-order model with multiple compartments. Respiratory impedance and derived parameters have been measured in 13 patients with acute heart failure or myocardial infarction. A comparison of the time dependence of the peripheral respiratory resistances with pulmonary wedge pressure measured by a Swan-Ganz catheter is presented.
