Background
Definition
Pathogenesis
Two-hit hypothesis: first hit is underlying patient factors causing adherence of neutrophils to the pulmonary endothelium; second hit is caused by mediators in the blood transfusion that activate the neutrophils and endothelial cells.
Differential
Can be confused or overlap with TACO or transfusion-associated volume/circulatory overload, which presents similarly but has evidence of increased BNP, CVP, pulmonary wedge pressure, and left sided heart pressures. Patients with TACO tend to improve with diuretic treatment
