First aid
You should reassure the patient, raise the patient's leg above the level of the heart with head flat on the floor, treat any wound or burn and immobilize fractures, loosen that tight clotting around neck chest and waist, maintain the patient's body warmth with a blanket or similar. do not use any source of direct heat, give small frequent amounts of water to the conscious patient who does not have abdominal trauma and who is unlikely to require an operation in the immediate future, monitor and record briefing holes and skin color at regular intervals, lastly place the patient in the recovery position if the person has difficult breathing, becomes unconscious and is likely to vomit.
hope it helps.
