b. Evaluate Casualty. The ventilator rescuer (the rescuer at the casualty's
Opens the casualty's airway (paragraph 3-6).
Checks for signs of breathing (paragraph 3-7).
(3) Administers two full breaths if spontaneous breathing is not present and
observes the casualty's chest to make sure that it rises (paragraph 3-9).
(a) If the airway is blocked, the ventilator rescuer opens the casualty's
airway more and tries to administer two ventilations again. If the ventilations are
unsuccessful, he tells the compressor rescuer to administer thrusts (paragraph 5-6f)
while he (ventilator rescuer) performs finger sweeps (paragraphs 5-6c) as needed until
the obstruction is removed.
(b) After the obstruction is removed, the ventilator rescuer administers
two breaths and two-rescuer CPR is continued.
(4) Checks for a pulse by feeling the carotid artery for 5 to 10 seconds
(5) Informs the compressor rescuer of the need for chest compressions by
saying, "No pulse," if a pulse is not detected.
c. Prepare for Chest Compressions. While the ventilator rescuer is evaluating
and ventilating the casualty, the compressor rescuer (the rescuer at the casualty's
Locates the site for administering chest compressions (paragraph 4-1d).
Positions himself to administer the compressions (paragraphs 4-1e and
d. Administer 30 Compressions. When the ventilator rescuer says, "No
pulse," the compressor rescuer administers 30 chest compressions at the rate of
approximately 100 compressions per minute. The sternum is depressed 1 1/2 to 2
inches with each compression.
(1) The force of the compression should be delivered straight down without
rocking the casualty. The fingers should not touch the casualty.
(2) The release part of the compression should be equal in time to the thrust
part of the compression. Both parts should be distinct (no bounce).
