Hypovolemic Shock: A Life-Threatening Medical Emergency

Hypovolemic shock occurs when the body lacks adequate blood volume, often resulting from catastrophic bleeds. Prompt medical attention is crucial, as untreated hypovolemic shock can be life-threatening.

Causes of Hypovolemic Shock

Catastrophic bleeds, defined as sudden and severe blood loss, can lead to hypovolemic shock. The rapid loss of blood causes a quick drop in blood pressure, resulting in shock.

Symptoms of Hypovolemic Shock

  • Pale or clammy skin
  • Rapid breathing
  • Rapid heartbeat
  • Confusion
  • Loss of consciousness in severe cases

First Aid for Hypovolemic Shock

Emergency services typically treat hypovolemic shock by replacing lost blood volume with fluids like saline solutions or blood transfusions. They may also administer medications to increase blood pressure. In first aid situations, we must focus on getting blood to the vital organs:

  1. Raise the patient's legs 15 to 30 centimetres to allow blood to flow back into their body.
  2. Keep the patient warm to aid blood flow, clotting, and comfort. Use a blanket, foil blanket, or spare clothing, ensuring the injury remains visible in case of further bleeding.
  3. Monitor and communicate with the patient, paying special attention to their breathing.

If you or someone you know experiences a catastrophic bleed, seek medical help immediately to prevent life-threatening complications from hypovolemic shock.
