First Aid for Shock
Shock is a critical, life-threatening condition that occurs when the circulatory system fails to provide adequate blood flow and oxygen to vital organs. Immediate first aid aims to stabilize the person, maintain vital organ perfusion, and prevent complications while emergency services are en route. Prompt recognition and action can prevent irreversible organ failure and save a life.
Quick Summary
Call emergency services immediately, lay the person flat with their legs slightly elevated if safe, keep them warm, and monitor breathing until paramedics arrive.

Step-by-Step Guide
Recognize the Warning Signs and Call Emergency Services
Quickly inspect the person for key clinical signs of shock, which include cool, clammy, or pale skin, rapid shallow breathing, a weak and rapid pulse, extreme weakness, confusion, or blue-tinged lips and fingernails. Immediately call 911 or your local emergency number. Clearly report the person's symptoms, apparent cause of injury, and whether they are conscious.
Important: Do not delay contacting emergency services to attempt first aid; physiological shock cannot be managed without professional medical interventions.
Position the Person Properly
Help the person lie down flat on their back to facilitate blood flow toward the heart and brain. If there are no suspected fractures or spinal injuries, elevate their feet approximately 6 to 12 inches (15 to 30 cm). If the person is vomiting, drooling, or bleeding from the mouth, roll them onto their side into the recovery position to keep the airway clear.
Important: Do not elevate the legs if you suspect head, neck, back, or pelvic trauma, or if elevation causes pain or breathing difficulty.
Control Severe External Bleeding
Check the body quickly for visible, heavy blood loss, which is the leading cause of hypovolemic shock. Apply continuous, firm direct pressure to any bleeding wounds using a sterile dressing, clean cloth, or your hands. If severe bleeding from an extremity does not stop with direct pressure, apply an emergency tourniquet several inches above the wound if you are trained to do so.
Important: Do not remove dressings that become soaked with blood; place additional pads on top and maintain firm, uninterrupted pressure.
Maintain Body Temperature
Preserve the person's core body heat, as hypothermia severely worsens shock by impairing blood clotting mechanisms. Cover them with a blanket, coat, or foil emergency blanket, even if the environment feels warm. If possible and safe, slide a blanket or jacket beneath the person to insulate them from cold or wet ground.
Important: Do not apply active heat sources such as hot water bottles or electric heating pads, as sudden peripheral vasodilation can divert vital blood flow away from central organs.
Loosen Restrictive Clothing and Provide Reassurance
Gently loosen belts, collars, ties, and any tight apparel around the neck, chest, and abdomen to ensure unrestricted breathing and venous return. Speak in a calm, steady voice to reduce panic, as emotional distress increases heart rate and oxygen demand. Instruct the person to remain completely still and avoid sitting up or walking.
Do Not Give Food or Fluids
Do not offer the person anything to eat or drink, even if they complain of severe thirst. Swallowing reflexes may be compromised during shock, creating a severe risk of choking or fluid aspiration into the lungs. Furthermore, patients presenting in shock frequently require emergency surgery requiring an empty stomach.
Important: Never administer water, food, or oral medications to a person experiencing physiological shock.
Continuously Monitor Breathing and Circulation
Stay with the person and recheck their airway, respiratory rate, and responsiveness every 2 minutes until emergency responders take over. If the person loses consciousness, stops breathing normally, or is only gasping, immediately place them flat on a firm surface and begin CPR. Deliver uninterrupted chest compressions at a rate of 100 to 120 per minute.
Important: If the person becomes unresponsive and stops breathing normally, begin CPR immediately without hesitation.
