If someone is taking a heart attack in the middle of the street you should ? what do you do, first aid wise, after you call for medical help. Do you still give him CPR if the victim becomes unconscious or would that damage the heart if you are pushing on the chest . Do you give him mouth to mouth? do you sit him/her down, get the victim to lie on the back, get the victim a seat? Is it better to get him somewhere warm/cool? Finally how do you tell if it is really a heart attack ? and do heart sufferers have any meds that you could use on them. What if its a stroke and you mistake it for a heart attack.?
