Shock: First Aid and Emergency Management
Medical shock is a critical, life-threatening condition where the circulatory system fails to deliver sufficient oxygenated blood to vital organs. It can be triggered by severe bleeding, heart attack, major trauma, severe burns, infection, or acute allergic reactions. Immediate first aid intervention and emergency medical care are vital to prevent irreversible organ damage and death.
Quick Summary
Call emergency services immediately, lay the person flat with legs slightly elevated if safe, keep them warm, and never give them anything to eat or drink.

Step-by-Step Guide
Call 911 or Local Emergency Services
Recognize the signs of circulatory shock, which include pale, cool, or clammy skin, rapid and shallow breathing, dizziness, and a weak, rapid pulse. Immediately call local emergency numbers or direct a specific bystander to make the call. Clearly describe the person's symptoms and state any known causes, such as visible bleeding, an injury, or an allergic reaction.
Important: Do not delay calling emergency services; shock is a progressive medical emergency that deteriorates rapidly without professional care.
Control Severe External Bleeding
If you observe significant external bleeding, treat it immediately to halt blood volume depletion. Apply firm, direct pressure over the wound using a clean cloth, sterile gauze, or gloved hands. If severe arterial bleeding on an arm or leg does not stop with direct pressure, apply an approved commercial tourniquet several inches above the wound if you are trained to do so.
Position the Person Correctly
Help the person lie flat on their back on a safe surface to encourage blood return to the heart and brain. If there are no signs of head, neck, spinal, or pelvic trauma, and no broken bones in the legs, elevate their legs approximately 6 to 12 inches (30 cm). If the person has chest pain, heart problems, or difficulty breathing, allow them to remain in a comfortable, semi-reclined seated position instead.
Important: Never move the person or elevate their legs if you suspect a head, neck, spinal, or pelvic injury.
Maintain Normal Body Temperature
Cover the person with a light blanket, jacket, or emergency foil thermal sheet to prevent heat loss and hypothermia. Hypothermia severely impairs blood clotting and worsens the body's response to shock. Place a barrier or blanket beneath them if they are lying on a cold, damp surface.
Important: Avoid applying direct heat sources such as hot water bottles or electric heating pads, which can dilate peripheral blood vessels and worsen central blood pressure.
Loosen Restrictive Clothing
Gently unbutton or loosen any tight clothing around the person's neck, chest, and waist, including collars, ties, belts, and tight waistbands. This eases breathing mechanics and promotes unrestricted venous blood flow back toward the heart. Reassure the person calmly and encourage them to remain as quiet and still as possible.
Withhold Food and Fluids
Do not give the person anything to eat, drink, or chew, even if they express severe thirst. In states of shock, digestion slows and protective airway reflexes weaken, significantly increasing the hazard of vomiting and choking. Additionally, withholding oral intake is essential in case emergency surgery requiring general anesthesia is needed upon arrival at the hospital.
Important: Never give water, food, or oral medications to someone in shock, as it presents a severe risk of fatal airway aspiration.
Monitor Breathing and Be Prepared for CPR
Continuously evaluate the person's breathing, pulse, and level of consciousness until paramedics arrive. If the person becomes unresponsive but continues breathing normally, carefully roll them onto their side into the recovery position to maintain an open airway and allow drainage of fluids. If the person stops breathing or only gasps intermittently, begin cardiopulmonary resuscitation (CPR) immediately.
