Blood transfusion is the process of transferring blood products into a person's circulation intravenously. [1] ... Because each unit of blood given carries risks, ...
In transfusion medicine, transfusion-associated circulatory overload (aka TACO) is a transfusion reaction (an adverse effect of blood transfusion) resulting in signs or symptoms of excess fluid in the circulatory system (hypervolemia) within 12 hours after transfusion. [2]
Transfusion-associated graft-versus-host disease (TA-GvHD) is a rare complication of blood transfusion, in which the immunologically competent donor T lymphocytes mount an immune response against the recipient's lymphoid tissue. [1]

Transfusion-related acute lung injury (TRALI) is the serious complication of transfusion of blood products that is characterized by the rapid onset of excess fluid in the lungs. [1] It can cause dangerous drops in the supply of oxygen to body tissues.
This greatly increases the risks of the transfusion. Each unit of platelets separated from donated whole blood is called a "platelet concentrate". [citation needed] Modern automatic thrombapheresis allows blood donors to give a portion of their platelets, while keeping their red blood cells and at least a portion of blood plasma. Therefore, no ...
Serious Hazards of Transfusion (SHOT) is the United Kingdom's haemovigilance scheme. It collects and analyses anonymized information on adverse events and blood transfusion reactions. When SHOT has identified risks related to transfusion, it produces recommendations within its annual reports to improve patient safety. These reports are freely ...
