ARDS is most commonly seen in which clinical settings?

• A. Sepsis, burns, and pancreatitis
• B. Chronic obstructive pulmonary disease
• C. Uncomplicated pneumonia in healthy individuals
• D. Acute pulmonary embolism

Answer: (A)

ARDS arises from a severe inflammatory injury to the lungs, so it most commonly appears in people with major systemic insults. Sepsis is the leading cause, driving a widespread inflammatory response that increases capillary permeability and damages the alveolar–epithelial barrier. Burns and pancreatitis similarly provoke intense inflammation and fluid shifts, promoting diffuse alveolar damage and noncardiogenic edema that define ARDS. In contrast, COPD and uncomplicated pneumonia in a healthy person are unlikely to trigger the diffuse, alveolar-capillary injury seen in ARDS, and acute pulmonary embolism causes a different problem—venous obstruction and hypoxemia from perfusion mismatch rather than the global inflammatory edema of ARDS. So the settings of sepsis, burns, and pancreatitis best fit the typical context in which ARDS develops.
