First Aid for Fainting

Published: October 19, 2026Updated: October 19, 2026

Fainting occurs when a temporary drop in blood flow to the brain causes a brief loss of consciousness. Prompt first aid helps restore blood circulation, protects the airway, and prevents injury from falling. Learn how to assist someone who has passed out and recognize when emergency medical services are needed.

Quick Summary

Lay the person flat on their back, elevate their legs if uninjured, ensure their airway is clear, and call emergency services if they do not wake within one minute.

Step-by-Step Guide

Position the Person Safely

Assist the person gently to the floor to prevent a fall injury. Lay them flat on their back. If there are no signs of injury or trauma, elevate their feet approximately 12 inches (30 cm) above heart level to encourage blood flow back toward the brain.

Important: Do not elevate the legs if you suspect head, neck, back, or spinal injuries, or if moving them causes pain.

Check Airway and Breathing

Look for normal chest rise and fall and listen for breath sounds. If the person is breathing normally, continue to monitor them closely. If they are unresponsive and not breathing or only gasping, immediately call emergency services and begin chest compressions (CPR).

Important: Call 911 or your local emergency number immediately and start CPR if the individual is pulseless or not breathing.

Loosen Restrictive Clothing

Loosen any tight collars, ties, belts, or waistbands to facilitate unimpeded respiration and circulation. Keep bystanders back to ensure adequate airflow around the person.

Place in the Recovery Position if Unresponsive

If the person remains unconscious but is breathing normally, gently roll them onto their side into the recovery position. This prevents the tongue from obstructing the airway and allows fluids or vomit to drain freely.

Important: Never shake the person, slap their face, or throw cold water on them to wake them up.

Prevent Premature Standing

Once the person regains consciousness, encourage them to stay lying flat for at least 10 to 15 minutes. Help them transition slowly—first to a sitting position, then standing only when feeling completely stable.

Important: Standing up too quickly can trigger a secondary drop in blood pressure, leading to another fainting episode.

Withhold Food and Drink Until Alert

Do not attempt to administer water, food, or medications while the person is recovering or drowsy. Once they are fully oriented, coherent, and sitting upright, you may offer small sips of cool water if they feel thirsty.

Important: Giving oral liquids to an uncoordinated or semi-conscious individual creates a severe choking and aspiration risk.

Frequently Asked Questions

What should I do if I feel like I am about to faint?

Lie down immediately and elevate your feet if possible. If you cannot lie down, sit down and place your head between your knees. Tensing your leg and abdominal muscles can also temporarily boost blood pressure back to your brain.

How long does a typical fainting spell last?

Most uncomplicated fainting episodes (vasovagal syncope) last between 20 seconds and one minute. Unconsciousness lasting longer than one minute requires immediate emergency medical evaluation.

When does fainting indicate a medical emergency?

Call emergency services if the faint is accompanied by chest pain, shortness of breath, irregular heartbeat, sudden severe headache, confusion upon waking, loss of bowel or bladder control, or if it occurred during strenuous exercise.

Should someone who fainted see a doctor even after fully recovering?

Yes, especially if it is their first episode, occurs frequently, or if the individual has an underlying cardiovascular condition, diabetes, or is pregnant. A physician should evaluate potential triggers and cardiac causes.
