PACKED RED BLOOD CELLS Meaning and
Definition
-
Packed red blood cells, commonly referred to as PRBCs, are blood components obtained through a process called centrifugation, in which a sample of whole blood is spun at high speeds to separate its various components. PRBCs are the concentrated form of red blood cells, with most of the plasma and platelets removed.
With a primary purpose of supplying oxygen to body tissues, red blood cells are responsible for transporting oxygen from the lungs to cells throughout the body, while simultaneously removing carbon dioxide for elimination. PRBCs are specifically used for blood transfusions to individuals who require an increase in red blood cell count due to various medical conditions, such as severe anemia, trauma, or surgical procedures that result in significant blood loss.
Packed red blood cells undergo strict processing procedures to ensure compatibility and minimize the risk of adverse reactions in recipients. They are typically stored in blood banks and frozen at temperatures below -65°C (-85°F) for long-term preservation. Prior to transfusion, PRBCs are thawed, washed, and prepared for administration in accordance with medical guidelines.
Transfusing packed red blood cells helps restore and maintain adequate oxygen-carrying capacity in individuals with compromised blood cell counts. Due to their concentrated nature, PRBCs deliver a higher concentration of red blood cells into the circulation, allowing rapid response to oxygen demands within the body.
