Clinical Features
It is often impossible to distinguish TRALI from adult respiratory distress syndrome. The typical presentation of TRALI is the sudden development of dyspnea, severe hypoxemia (O2 saturation <90% in room air), hypotension, and fever that develop within 6 hours after transfusion and usually resolve with supportive care within 48 to 96 hours. Although hypotension is considered one of the important signs in diagnosing TRALI, hypertension can occur in some cases.

—Christopher Lasch (b. 1932)
