If the casualty still is not breathing, say "No breathing" and give two full
Check for carotid pulse. If there is no pulse, say "No pulse."
d. At the same time, the second rescuer (the compressor) should position
himself by the casualty's side and:
Find the site for external chest compressions.
Place his hands in the correct position for external chest compressions.
(3) After the first rescuer says "No pulse", the compressor should begin
external chest compressions.
e. The rescuers continue to administer CPR cycles (5 compressions and 2
breaths per cycle).
1-19. RESCUERS CHANGE POSITIONS IN TWO-RESCUER CARDIOPULMONARY
a. A position exchange (figure 1-15) is used to give tie rescuer at the chest a
rest. If there are other CPR qualified persons in the area, a switch can be used to bring
a new person in and take a tired rescuer out.
b. Follow this procedure to make a switch in rescuers:
(1) The first rescuer (person at the chest) initiates the exchange by
counting, "Change-one thousand, two-one thousand, three-one thousand, four-one
thousand, five-one thousand."
(2) Then, the second rescuer gives a breath and moves to the position for
chest compressions while the first rescuer moves to the position for rescue breathing.
The rescuers do not change sides.
(3) The first rescuer (now at the casualty's head) checks the casualty's
pulse (takes about 5 seconds). If no pulse is felt, he tells the rescuer at the chest. The
first rescuer continues to administer rescue breathing, and the second rescuer
examines the casualty for injuries. If there is still no pulse during a second check, the
rescuer at the chest is told. The other rescuer gives the casualty a breath, and both
rescuers continue to administer CPR.
