Transfusion associated circulatory overload (TACO) is a serious but under-recognised complication of blood transfusion. While the exact incidence rate is unknown the associated morbidity and mortality make this a transfusion reaction worthy of attention. This article provides details of a critical incident involving TACO followed by a literature review and discussion written from the perspective of a student ODP. The goal of this article is to raise awareness of TACO amongst hospital staff to facilitate faster recognition and earlier intervention in future events.
