First Aid for Shock
Shock is a life-threatening medical emergency that occurs when tissues and organs fail to receive adequate blood flow and oxygen. It can be triggered by severe trauma, major blood loss, heart failure, severe infections, or anaphylaxis. Immediate recognition and emergency first aid are essential to stabilize the person while waiting for medical help.
Quick Summary
Call emergency services immediately, position the person flat on their back with legs slightly elevated if safe, keep them warm, and monitor breathing until paramedics arrive.

Step-by-Step Guide
Call Emergency Services Immediately
Physiological shock is a critical emergency that cannot be treated with first aid alone. Dial 911 or your local emergency number right away. Clearly inform the dispatcher of the person's symptoms, any known injuries or underlying conditions, and your exact location.
Important: Do not delay calling emergency responders; tissue damage rapidly progresses when blood pressure collapses.
Position the Person Correctly
If the person is conscious and shows no signs of spinal, head, neck, or pelvic trauma, lay them flat on their back. Elevate their feet roughly 6 to 12 inches (15 to 30 cm) using folded clothing or pillows to promote blood return to vital organs. If elevating the legs causes pain or breathing difficulty, keep them completely flat.
Important: Do not move the person or elevate their legs if you suspect spinal trauma, pelvic fractures, or broken leg bones.
Control Any Major Bleeding
If shock is caused by external trauma or hemorrhage, immediate bleeding control is vital. Apply firm, continuous direct pressure over the bleeding site using a clean cloth, sterile bandage, or your hands. If severe limb bleeding does not stop with direct pressure, apply an emergency tourniquet above the wound if trained to do so.
Keep the Person Warm
Low body temperature interferes with the blood's clotting ability and accelerates shock progression. Cover the person with a blanket, coat, or thermal wrap to preserve body heat. Loosen any tight clothing around the neck, chest, and waist to facilitate unrestricted circulation and respiration.
Important: Do not apply direct heat sources like hot water bottles or heating pads, as artificial heating can cause peripheral blood vessels to dilate and drop blood pressure further.
Do Not Give Food or Drink
Even if the person complains of severe thirst or a dry mouth, do not give them anything to eat or drink. Shock slows digestion and can cause sudden vomiting, creating a high risk of airway aspiration. Additionally, the patient may require urgent surgery under anesthesia upon arriving at the hospital.
Important: Never administer liquids by mouth, as choking and pulmonary aspiration can prove fatal.
Turn to the Recovery Position if Necessary
If the person is unconscious but breathing normally, or if they begin vomiting or drooling fluids, gently roll them onto their side into the recovery position. This ensures the tongue does not block the airway and allows fluids to drain freely from the mouth.
Important: Avoid rolling the person if a spinal cord injury is suspected unless it is absolutely necessary to clear a blocked airway from vomit.
Continuously Monitor Vitals and Prepare for CPR
Remain with the person and continuously check their level of responsiveness and breathing pattern until medical personnel take over. If the person becomes unresponsive and stops breathing normally (or begins gasping intermittently), begin cardiopulmonary resuscitation (CPR) immediately with continuous chest compressions.
