It is used in the treatment of massive bleeding, in exchange transfusion, and when people donate blood to themselves (autologous transfusion). [1] [2] One unit of whole blood (approximately 450 mL) increases hemoglobin levels by about 10 g/L. [3] [4] Cross matching is typically done before the blood is given. [2] [5] It is given by injection ...
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. [1] A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL.

Patient Blood Management (PBM) [1] [2] [3] is a set of medical practices designed to optimise the care of patients who might need a blood transfusion.

Each unit transfused increases the associated risks of transfusion such as infection, transfusion associated circulatory overload and other side effects. Transfusion of a single unit also encourages less wastage of blood products [5] and can be cost-effective. Single unit transfusion can be as part of an institutional or national guidelines [3 ...
Australia has national blood services operated by the Australian Red Cross Blood Service. There are a series of guidelines and standards relevant to the laboratory released by the National Association of Testing Authorities, Australia (NATA), [2] Australian and New Zealand Society of Blood Transfusion (ANZSBT) [3] and RCPA.

Transfusion dependence occurs when an average of more than 2 units of blood transfused every 28 days is required over a period of at least 3 months. [ 6 ] [ 7 ] Myelodysplastic syndromes is often only diagnosed when patients become anemic, and transfusion-dependent thalassemia is diagnosed based on gene mutations .
