g. Evaluate Your Efforts.
(1) If your ventilations were successful (chest rose and fell), check the
infant's pulse (paragraph 6-5).
(a) If the pulse is absent, administer CPR (paragraph 6-6).
(b) If a pulse is present, administer ventilations at the rate of one
ventilation every 3 seconds (20 ventilations per minute). Check the pulse again every
few minutes. Also check for spontaneous breathing when you check the pulse. If the
pulse is absent, administer CPR.
(c) Continue your efforts until the infant is breathing spontaneously or
until you are relieved by a physician or other medical authority. If possible, evacuate
the casualty to a medical treatment facility as you perform rescue breathing/CPR.
(2) If your ventilations were not successful (air did not go in and the chest
did not rise), perform backblows (if no spinal or head injury), chest thrusts, finger
sweeps (when appropriate), and ventilations as given in the following paragraphs until
the obstruction is removed.
h. Call for Help. Call for help again. If a second rescuer is available, have him
seek medical assistance.
i. Position Infant for Backblows. Position the infant for backblows using the
procedures given in paragraph 7-3b(1) if the casualty is a small infant and in paragraph
7-3b(2) if the casualty is a large infant.
j. Administer Backblows. Administer five backblows by striking the infant on
the spine between his shoulder blades with the heel of your free hand. The five blows
should be delivered within 3 to 5 seconds.
k. Position Infant for Chest Thrusts. Position the infant for chest thrusts using
the procedures given in paragraph 7-3d(1) if the casualty is a small infant and in
paragraph 7-3d(2) if the casualty is a large infant.
l. Administer Chest Thrusts. Perform chest thrusts in the manner described
in paragraph 7-3e. Continue until the obstruction has been expelled or until you have
administered five chest thrusts.
