The best way to check if a person is unconscious is to tap the shoulder and shout "Are you okay?" This is the first step in assessing a person's level of consciousness. If there is no response, it is important to check for breathing, circulation, and other signs of life. If the person is not breathing or does not have a pulse, CPR should be started immediately. It is important to call emergency services as soon as possible in any situation where a person is unconscious.
