4 Send someone to get help.
5 If no pulse is felt, begin CPR immediately. If a pulse can be felt,
continue with rescue breathing procedures given in the next paragraph.
(e) Continue rescue breathing. If the casualty's heart is beating and he
is not breathing on his own, continue to administer rescue breathing using the
procedure given below. Perform ventilations at a rate of one ventilation every 5
seconds (12 ventilations per minute). Continue to keep the casualty's airway open while
performing the ventilations, and follow this procedure:
1 Take a deep breath.
2 Pinch the casualty's nostrils closed; use the thumb and index
finger of your hand on his forehead to do this.
3 Place your mouth over the casualty's mouth, making sure that a
tight seal is formed.
4 Blow into the casualty's mouth. As you blow, observe the
casualty's chest. If his chest does not rise, a sufficient amount of air is not getting into
his lungs. This may be caused by these factors: inadequate positioning of the
casualty's head, chin, or neck; air leaking from the casualty's nose; air leaking from
around your mouth; an airway obstruction; or the breath not being delivered with
sufficient force. If a problem exists, correct the problem and continue administering
5 Remove your mouth from around the casualty's mouth and
release his nose. This allows him to exhale. Remember, the casualty's airway must be
kept open so that he can exhale.
6 Recheck the casualty's pulse after every 12 breaths (once per
minute). If the pulse is absent, begin administering chest compressions at once.
7 Continue administering rescue breathing at the rate of one
breath every 5 seconds until the casualty begins breathing on his own, until you are
relieved by a qualified person, until you are ordered to stop by a doctor, or until you are
too exhausted to continue.
8 If the casualty begins breathing on his own, monitor him in case
his breathing stops again.
9 When possible, evacuate the casualty for further evaluation and
treatment by a doctor. If the casualty is not breathing on his own, continue
administering rescue breathing during the evacuation.
