i stumbled across a scene where an elderly man had just collapsed to the ground all of a sudden unresponsive. his breathing was difficult (one big inhale maybe once per 15 seconds) and his face was blue. i did cpr on him and told bystanders to call an ambulance. pretty soon another guy arrived and took over the cpr and i coordinated people in the scene. i heard the next day that the man arrived to the hospital alive but other than that i don't know what happened to him.
