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.
