Controlling external bleeding is a crucial component in preventing and managing shock because significant blood loss is a primary cause of shock, particularly hypovolemic shock. When an individual loses a substantial amount of blood, their body's ability to maintain adequate circulation and deliver oxygen to vital organs is compromised. By effectively controlling bleeding—either through direct pressure, tourniquets, or other methods—first responders can stabilize the patient and help prevent the progression of shock.

In addition to addressing blood loss, other strategies like providing high-flow oxygen and maintaining body temperature also support the overall management of shock. However, stopping the source of bleeding directly addresses one of the most immediate and life-threatening factors involved in shock. Pain management, while important in an overall emergency care setting, does not directly impact the physiological aspects of shock in the same critical manner that controlling external bleeding does.
