If unable to blow air into the patient, place the heel of one hand on the abdomen above the navel and below the ribs with your fingers pointing toward the patient's head. Place your other hand on top and give 6-10 sharp thrusts upward and inward. If airway is still blocked, repeat abdominal thrusts until successful or until help arrives. A child may be turned over an adult's arm and struck between the shoulder blades. The child's head must be lower than its body.
Abdominal thrusts can cause internal injury.
If they are used the patient must have medical attention.
