A blood transfusion is the transfer of blood or blood products from one person (donor) into another person's bloodstream (recipient). This is usually done as a lifesaving maneuver to replace blood cells or blood products lost through severe bleeding, during surgery when blood loss occurs or to increase the blood count in an anemic patient.
Blood transfusions can be a life saving measure. Volunteer donor blood usually is readily available, and when properly tested has a low incidence of adverse events. The likelihood of contracting infections from a blood transfusion is very low. Blood conserving techniques are an important aspect of limiting transfusion requirements. Blood banks are responsible for collecting, testing and storing blood. People with Type O, negative blood are considered universal donors as it is safe to transfuse to nearly everyone.
