First Aid for Shock
Medical shock is a life-threatening emergency caused by insufficient blood flow and oxygen delivery to vital organs. Prompt first aid focuses on summoning emergency services, maintaining circulation, and preventing hypothermia while avoiding interventions that could worsen the patient's condition. Rapid recognition and supportive care before professional help arrives can mean the difference between recovery and organ failure.
Quick Summary
Call emergency services immediately, lay the person flat with legs elevated if uninjured, keep them warm, and do not give any food or drink.

Step-by-Step Guide
Call Emergency Services Immediately
Dial 911 or your local emergency number as soon as you recognize signs of shock, such as pale, clammy skin, rapid breathing, and confusion. Shock is a progressive, life-threatening condition that cannot be managed at home and requires advanced medical care. Provide the dispatcher with your exact location and clearly describe the person's symptoms and possible cause.
Important: Do not delay calling emergency responders to perform other first aid steps; shock can progress to cardiac arrest within minutes.
Position the Person Correctly
Gently lay the person flat on their back to improve venous return to the heart. If there is no suspicion of head, neck, spinal, or pelvic injury, elevate their legs approximately 12 inches (30 cm). If the person is vomiting, bleeding from the mouth, or unconscious, place them in the recovery position on their side to maintain an open airway.
Important: Do not move the person or elevate their legs if you suspect spinal trauma, pelvic fractures, or leg fractures, as this may exacerbate internal bleeding and neurological injury.
Control Severe External Bleeding
If physical trauma is present, immediately inspect the body for life-threatening hemorrhage, which is a leading cause of hypovolemic shock. Apply firm, direct pressure to any bleeding wounds using a sterile gauze pad or clean cloth. Maintain continuous pressure without lifting the cloth to check the wound until medical help arrives.
Important: If bleeding is heavy and arterial, and direct pressure fails on an extremity, apply a commercial tourniquet if you are trained to do so.
Monitor Airway, Breathing, and Pulse
Continuously assess the patient's responsiveness and quality of breathing. Ensure the airway remains clear of secretions, vomit, or foreign objects. If the person becomes unresponsive and stops breathing normally (or is only gasping), begin cardiopulmonary resuscitation (CPR) immediately and retrieve an automated external defibrillator (AED) if available.
Maintain Normal Body Temperature
Impaired circulation makes it difficult for the body to regulate temperature, predisposing the person to hypothermia, which impairs blood clotting. Cover the person with a blanket, jacket, or emergency foil blanket to preserve body heat. Place an insulating layer beneath them if they are lying on a cold surface, but avoid applying direct heat sources like hot packs.
Loosen Restrictive Clothing and Provide Reassurance
Loosen belts, collars, ties, and tight garments around the chest, neck, and waist to facilitate unrestricted respiration and blood flow. Speak to the person in a calm, soothing voice to help reduce panic, as extreme anxiety increases myocardial oxygen consumption. Stay with the person continuously until emergency medical personnel take over care.
Withhold All Food and Drink
Do not give the person anything to eat, drink, or chew, even if they complain of severe thirst or a dry mouth. Gastrointestinal blood flow is drastically reduced during shock, which can cause immediate vomiting and lethal airway aspiration. Furthermore, oral intake may complicate emergency anesthesia if urgent surgery is required upon hospital arrival.
Important: Never administer oral fluids, medications, or alcohol to someone in shock, even if they insist they feel faint or dehydrated.
