What you need to stop the bleed

An analyzer collects blood from Airman 1st Class Mason Amadio, 8th Expeditionary Airlift Squadron weapons systems controller, at Al Udeid Air Base, Qatar, Jan. 24, 2023. This machine separates red blood cells, white blood cells, platelets and plasma by centrifugation. Using sterile equipment, the technician directs the platelets into a collection bag while the rest of the blood is returned to the donor or discarded. (U.S. Air Force photo by Tech. Sgt. Sahara L.
