This is a case highly suggestive of transfusion-associated circulatory overload (TACO). The patient was saturating well on room air prior to the packed red blood cell (PRBC) transfusion. Shortly after completing the PRBC transfusion, the patient developed dyspnea and crackles on auscultation. A radiograph of the chest revealed findings suggestive of fluid overload and thus, TACO.
