Understanding the blood group system and blood transfusions.

Having a blood transfusion carries risks for patients. To minimise these risks, nurses must be aware of the ABO group system, components of blood and how they should be stored, handled, checked and administered. They must also be aware of possible adverse events during or after transfusion, how to monitor patients and how to deal with adverse events should they occur. All staff involved at any stage must be trained and aware of hospital policy and all actions must be accurately recorded to ensure the process is as safe as possible.
