■ If the person is unconscious, don’t move them: call for an ambulance. If the person is conscious, help them to sit up and place a cold pack of ice wrapped in a clean cloth on any injury to reduce swelling.
■ Call an ambulance if the patient’s condition deteriorates.
■ Get the patient assessed by a doctor even if they were only unconscious for a few moments.
■ Continue to monitor the patient’s condition: they should rest under supervision for 24 hours. Call the doctor or an ambulance if they suffer nausea or vomiting, visual disturbance, breathing difficulties or disorientation.
