As an expert in emergency medical response, I would advise the following steps if you find someone unconscious: 1. Call or tell someone to call 911 immediately. It's crucial to get professional medical help as soon as possible. 2. Check the person's airway to ensure it's clear of any obstructions. Tilt their head back slightly and lift the chin to open the airway. 3. Check for breathing by looking for chest movement, listening for breath sounds, and feeling for air on your cheek. 4. Feel for a pulse, typically on the neck, to determine if the person has a heartbeat. 5. If there is no breathing or no pulse, begin CPR. Place the person on their back and start chest compressions and rescue breaths. 6. If the person is breathing and lying on their back, and you do not think there is a spinal injury, carefully roll the person toward you onto their side. This is known as the recovery position and can help keep the airway open. read more >>
