An unconscious or having dizziness should be under constant supervision, because the sudden vomiting could block the airways. It is good to put the victim in part on his chest, partially on the side of his head to one side distorted. Shoulder appearing below should be drawn from the rear, and one arm bent, his hand close to his face. Lower leg should be straight, and the upper bent, with the rate on the first leg of the knee. This position is often used in first aid.
