When checking for consciousness, it is important
to consider that the person may be sleeping or resting in which
case nothing is wrong. However, if this is not the case and
the person shows no signs of alertness or awakeness after verbal
and painful stimulation, then this is abnormal. There is a problem.
It can be due to multiple causes, as a rescuer you are not responsible
for diagnosing the patient but moreover getting the ball rolling.
That is to say calling 911 for help, checking the ABC's and
performing CPR/defibrillation if necessary.
