Chapter 15: Acute Pulmonary Edema

Life-threatening, acute development of alveolar lung edema due to one or more of the following:
  1. Elevation of hydrostatic pressure in the pulmonary capillaries (left heart failure, mitral valve disease).
  2. Specific precipitants (Table 15-1), resulting in cardiogenic pulmonary edema in pts with previously compensated heart failure or without previous cardiac history.
  3. Increased permeability of pulmonary alveolar-capillary membrane (noncardiogenic pulmonary edema). For common causes, see Table 15-2.
TABLE 15-1: Precipitants of Acute Pulmonary Edema
Acute tachy- or bradyarrhythmia
Infection, fever
Acute MI
Severe hypertension
Acute mitral or aortic regurgitation
Increased circulating volume (Na+ ingestion, blood transfusion, pregnancy)
Increased metabolic demands (exercise, hyperthyroidism)
Pulmonary embolism
Noncompliance (sudden discontinuation) of chronic heart failure medications
