(c)
Open the casualty's airway. Give him two rescue breaths (full, slow
breaths).
(d) Determine the proper hand position. Start 15 more external chest
compressions at a rate of 80 to 100 chest compressions per minute.
(e) Do four complete cycles of 15 compressions and two ventilations.
d. Reassessment. Reassess the casualty after four cycles of compressions
and ventilations.
(1) Check to see if the casualty's carotid pulse has returned. (It should take
about 5 seconds to check.) If the casualty still has no pulse, begin CPR again by giving
two ventilations then 15 compressions. If the casualty's pulse has resumed, go to the
next step.
(2) Check to see if the casualty is breathing. (This check should take from 3
to 5 seconds.) If the casualty is breathing, check his breathing and pulse closely. If the
casualty is NOT breathing, start rescue breathing at 12 times per minute. Also, monitor
the pulse closely.
(3) If it is necessary to continue CPR, stop and check every few minutes to
see if the casualty's pulse has started and if he has begun breathing again. Be careful
not to stop CPR for more than 7 seconds at a time unless something very unusual is
happening.
NOTE:
One-rescuer CPR is summarized in figure 1-13.
