(a) Count out loud, "One and two and three and four and five and six
and seven and eight and nine and ten and eleven and twelve and thirteen and fourteen
and fifteen and...."
(b) Push down on the sternum when you say a number.
Release the pressure when you say "and."
h. Administer Two Breaths. Immediately after giving the thirtieth chest
compression, move your hands to the casualty's head, open his airway (paragraph 3-6),
and administer two breaths (paragraph 3-9). Each breath should take about 1 second
to administer. Observe the casualty's chest out of the corner of your eye to make sure
that the chest rises when you blow into the casualty's mouth (or nose or stoma). The
procedure should be completed within 3 to 5 seconds.
i. Prepare to Administer Chest Compressions. After the second breath,
relocate the compression site (landmark) over the lower half of the casualty's sternum.
Use the procedure given in paragraph d. Do not guess where the site is located.
Position your hands, lock your elbows, and move your shoulders over your hands.
j. Perform Four More Cycles of Cardiopulmonary Resuscitation. Administer four
more CPR cycles. A one-rescuer CPR cycle is sometimes referred to as a 30:2 cycle. Each
cycle consists of administering 30 chest compressions (paragraph g) followed by administering
two breaths (paragraph h). You have now administered five complete CPR cycles (150
compressions and 10 breaths). About 2 minutes have elapsed since you began the first
k. Check for Pulse and Breathing. After you have administered the two full
breaths of the fifth CPR cycle, check the carotid pulse (paragraph 3-11) again to see if
his heart has resumed beating on its own. At the same time, check for signs that
spontaneous breathing has resumed (paragraph 3-7). The check should take about 5
seconds. CPR should not be stopped for more than 10 seconds.
(1) If the casualty has resumed adequate breathing on his own, stop
administering CPR and begin checking for other injuries. Remember to keep his airway
open and check his breathing every few minutes if he does not regain consciousness.
Resume administering rescue breathing or CPR if the breathing stops.
(2) If the casualty has a pulse, but has not resumed breathing on his own,
proceed to administer rescue breathing (paragraph 3-12). Check the casualty's pulse
after every 12 breaths. If you find the casualty's pulse to be absent, resume
