My God, it's so responsible to organize a concert or something like that, it's so many people, it's unreal. Of course, there should be an ambulance at such events and probably more than one team. I advise you to contact this company https://www.valhallamedics.com/the-best-emt-set-medics-for-your-events for help. I know firsthand that they employ professional doctors who have helped more than one person.
