Transfusion-Associated Circulatory Overload (TACO)

Transfusion-Associated Circulatory Overload (TACO) is a condition that can occur after someone receives a blood transfusion. It happens when the volume of blood being transfused is too much for the heart and circulatory system to handle, leading to fluid overload. Symptoms may include difficulty breathing, high blood pressure, and swelling. TACO is more common in older adults or those with heart problems. To prevent it, healthcare providers monitor patients closely during transfusions and may give blood more slowly or in smaller amounts if needed.
