Electrical shock often renders the casualty unconscious and causes difficulties in breathing and heartbeat.
If the casualty is unresponsive, open his airway and check for breathing. If the casualty is not breathing, check his pulse.
a. If no pulse is present, perform cardiopulmonary resuscitation.
b. If a pulse is present, administer mouth-to-mouth resuscitation. Continue to check for a pulse every 12 breaths.
c. If the casualty resumes breathing on his own, continue with your evaluation.
CAUTION: Never attempt to administer mouth-to-mouth resuscitation until the wire and the casualty have been separated.
