The Mayo Clinic Blood Donor Center collects about 60 units of blood from donors on a daily basis, but if someone comes in with a severe injury, they can use up a lot of the supply. Blood transfusions are the number one procedure done in hospitalized patients today and the blood donated at the Mayo Clinic stays local, supplying 70 percent of the blood used at the facility.
A video recently published on Fox 47 features blood transfusions at Mayo Clinic, highlighting a trauma patient requiring a blood transfusion and a surgery patient needing a blood transfusion after losing a lot of blood.
According to Justin Kreuter, M.D., Mayo Clinic Blood Donor Director, "There's no substitute for blood. There's no substitute available in the U.S. for red cells, platelets, or plasma. We can't manufacture these things."
