Why Patient Blood Management or Blood Conservation?

See patient brochure, "You may need a blood transfusion: Risks and benefits of transfusions".

Although blood is the safest it has ever been and has many benefits, blood products are not without risk.


What does research say about the risks of transfusions?

  • Researchers are constantly looking for better tests to lower the risks from transfusion.
  • The numbers below are from studies done in Canada from 1999-2000. The larger the number in the column on the right side (your chances), the lower the risk that a transfusion will cause the problem listed on the left side.
