(b) If the casualty has spontaneous pulse and respiration, the new
ventilator rescuer maintains the casualty's airway and monitor his respirations and
pulse, while the other rescuer checks the casualty for injuries.
j. Evacuate the Casualty. If possible, evacuate the casualty to a medical
treatment facility. Continue administering CPR or rescue breathing as needed. If the

a. Identify Self. The second rescuer informs the first rescuer that he is qualified
to assist the first rescuer by saying, "I know CPR," or a similar comment.

functions and to lessen the chance of physical contact between the rescuers. The
second rescuer then kneels near the casualty's chest in position to administer chest
The first rescuer continues to perform one-rescuer CPR while the second
rescuer identifies and positions himself.
c. Administer Chest Compressions. After the first rescuer administers two full
breaths to the casualty, the second rescuer administers thirty chest compressions. The
first rescuer remains at the casualty's head and checks the casualty's carotid pulse to
determine the effectiveness of the chest compressions.
