Pretreating red blood cells with nitric oxide may reduce side effect linked to transfusions

A new treatment may diminish a dangerous side effect associated with transfusions of red blood cells (RBCs) known as pulmonary hypertension, an elevated blood pressure in the lungs and heart that can lead to heart failure, suggests a new study. The treatment involves exposing RBCs that have been collected, processed and stored for transfusion to the gas, nitric oxide.
