If you find a person unconscious, or see him or her collapse, then you will need to check to see if he or she is responsive. Shake the person and shout to make sure that he or she is not sleeping. Pinch an infant or young child to try to wake him or her up.
You should call 911 or have someone else call it. If there is another person present, then one of you can call 911 while the other one administers CPR. Sudden cardiac arrest can result in death if it is not treated within a few minutes.
