red blood cell transfusion

Red blood cell transfusion involves giving a patient donated blood that contains red blood cells. These cells carry oxygen from the lungs to the rest of the body, which is vital for energy and organ function. Transfusions are used when someone has anemia (low red blood cell count), or has lost blood from injury or surgery. The process is performed in a medical setting using sterile equipment. Blood typing and compatibility testing ensure the donor blood matches the patient, reducing the risk of reactions. Overall, transfusions help improve oxygen delivery and support recovery in various medical conditions.
