Abstract
The pathophysiologic mechanism of the pulmonary edema may sometimes be gleaned from the patient’s history, physical examination, laboratory data, and chest radiograph. This chapter focuses on the cardiogenic causes of pulmonary edema. Hydrostatic pulmonary edema includes cardiogenic causes, colloid osmotic pressure (COP) problems, and rare states resulting in negative interstitial pressure such as rapid re-expansion of a pneumothorax or acute airway obstruction. Cardiogenic pulmonary edema can be divided into disease resulting from systolic dysfunction, diastolic dysfunction, or valvular disease. The diagnosis of pulmonary edema is summarized in a table. The treatment of acute pulmonary edema in pregnancy depends on whether the excessive accumulation of extravascular lung water is due to increased hydrostatic pressures, to increased capillary permeability, or to one of the poorly understood causes, such as tocolytic-induced pulmonary edema or preeclampsia. Tocolytic-induced pulmonary edema is the etiology most amenable to prevention by the obstetrician. © 2019 John Wiley & Sons Ltd. Published 2019 by John Wiley & Sons Ltd.
