The best way to get your proper balance of vitamins and minerals is to eat a well balanced meal.
That would be the nervous system.
Always check for a pulse
If person has collapsed like in this scenario, someone else should call an ambulance while you continue to assess the situation (unless you are the only person their to help. If so, begin the defibrillator process first then call after you have finished all instructions given).
Have someone else run to get the nearest defibrillator possible.
The defibrillator itself with start to talk, telling you instruction you must follow carefully, once those instructions are complete make sure you have absolutely no contact with the body as it will start its electrical pulse
If by chance the person has their wallet accessible anywhere beside their clothing (thing purse or maybe they had dropped it earlier) try to get as much information as possible about the person to the emergency services as possible)
Things to look for are drivers license, business card, sometimes a medical card if this person has any other medical problems (if so tell emergency services if they are still on the phone at this point or when they arrive on the scene)
Send someone outside to wait for emergency services to guide them to wear you are at and never leave the patient alone
