First Aid for Fainting
Fainting, or syncope, is a sudden, temporary loss of consciousness usually caused by a transient decrease in blood flow to the brain. Most fainting episodes resolve quickly on their own, but prompt first aid helps restore circulation and prevents injury from falling. Learn how to assist someone who feels faint or has lost consciousness, and recognize when medical care is necessary.
Quick Summary
Lay the person flat on their back, elevate their legs if no injury is suspected, ensure they are breathing normally, and allow them to rest before attempting to stand.

Step-by-Step Guide
Position the Person Safely
Assist the person gently onto their back on a flat surface. If there are no signs of head, neck, or spinal trauma, elevate their feet approximately 12 inches (30 cm) above heart level to promote venous blood return to the brain. If the person has fallen and sustained an injury, keep them still and avoid moving their neck or spine.
Important: Do not elevate the legs if you suspect a head, neck, back, or hip injury, or if elevating causes pain.
Check Responsiveness and Breathing
Gently tap the person's shoulder and ask loudly, 'Are you okay?' Look for normal breathing by observing their chest rise and fall for up to 10 seconds. If the person is not breathing normally, is gasping, or remains completely unresponsive, call emergency services immediately and begin cardiopulmonary resuscitation (CPR).
Important: If the person has no pulse or is not breathing, call 911 immediately and begin chest compressions.
Loosen Restrictive Clothing
Unbutton tight collars, loosen ties, and unbuckle belts or restrictive waistbands to facilitate unhindered breathing and circulation. Ensure the surrounding area has adequate ventilation by opening windows or fanning fresh air toward the person. Keep crowds back to ensure sufficient airflow and comfort.
Prevent Choking and Manage Vomiting
If the person begins to vomit or bleed from the mouth, roll them carefully onto their side into the recovery position to keep the airway clear. Do not administer any food, water, or medication until the individual is fully alert, coherent, and seated upright. Never slap the person or splash cold water on their face, as this does not speed recovery and can lead to aspiration.
Important: Never offer liquids or food to someone who is drowsy or semi-conscious due to the high risk of choking.
Monitor Recovery and Gradual Return to Sitting
Most simple fainting episodes resolve within 20 to 60 seconds. Once the person regains consciousness, encourage them to remain lying down for at least 10 to 15 minutes to prevent a secondary syncopal episode. When they feel ready, help them move to a seated position first, waiting a few minutes before attempting to stand.
Important: Do not allow the person to stand up quickly, as sudden postural changes can trigger an immediate recurrence.
Evaluate for Red Flags and Seek Emergency Care
Call emergency medical services immediately if the person remains unconscious for longer than one minute, is pregnant, or has a known history of heart disease. Seek urgent evaluation if the episode was accompanied by chest pain, shortness of breath, palpitations, sudden severe headache, or signs of a stroke such as facial drooping or slurred speech.
Important: Fainting that occurs during exertion, while lying flat, or with chest pressure requires urgent emergency medical evaluation.
