There are some recommendations when calling 9-1-1 in case of chest pain: pain lasts over a few minutes, avoid driving to hospital, making sure door of the home is unlocked, making sure patient has a phone with him and patient may be directed to chew and swallow an aspirin.
Dr. Jonathan Fialkow, Chief Population Health Officer with Baptist Health South Florida, advises always asking for help in case of severe chest pain, whatever it is calling 9-1-1, a relative or a friend.
