What is the most common condition associated with acute lung injury and ARDS?

• A. Septic shock
• B. Cardiogenic shock
• C. Anaphylactic shock
• D. Neurogenic shock

Answer: (A)

Sepsis, especially septic shock, is the most common condition associated with acute lung injury and ARDS. The systemic inflammatory response to infection damages the alveolar-capillary barrier, causing noncardiogenic pulmonary edema, diffuse alveolar damage, and severe hypoxemia. This makes septic shock the leading precipitating condition for ALI/ARDS in adults. Other shocks (cardiogenic, anaphylactic, neurogenic) can impair ventilation or cause edema, but they are not the typical trigger for the noncardiogenic lung injury seen in ARDS.
