Blood is emergency infrastructure

Quick answerWhen someone is bleeding severely, the blood that saves them was donated days earlier and is already on the shelf. Trauma care, surgery, and a growing number of ambulances and helicopters depend on a steady supply that comes entirely from donors.
Prehospital blood: blood before the hospital
Prehospital blood means giving blood to a bleeding patient in an ambulance or helicopter, before they reach the hospital. Expanding access to it could save thousands of lives a year, and it depends on a steady donor supply.
Why whole blood matters in emergencies
Whole blood contains red cells, plasma, and platelets together, which can be valuable in major bleeding. Some emergency systems are returning to whole blood for trauma care.
Blood and trauma care
Severe injuries can cause rapid, life-threatening blood loss. Trauma teams rely on a ready supply of donated blood to replace what a patient loses while they are stabilized.
O negative and emergency readiness
O negative red cells can be given to almost any patient, so they are used in emergencies before a blood type is known. That makes O negative donors vital to emergency readiness, though every type is needed.
Advocating for blood supply and access
Beyond donating, you can support policies and programs that strengthen the blood supply and expand prehospital blood. Point professionals and officials to recognized resources rather than acting clinically yourself.
Donate to support trauma and emergency care
The most direct way to support emergency readiness is to donate, especially whole blood or, for O type donors, the red cell donations that emergencies depend on. Find a center and book a time.
