>>Good one about the aspirin, too. I personally prefer Ibuprofin for getting rid of my own headaches and muscle aches, but aspirin seems more universally useful. Can it be used on someone exhibiting the signs of of a heart attack? If so, what would the dosage be on a 150 lb. adult male? <br><br>Wow. Colour me embarrassed - I didn't know the answer to that and had to check with a couple of the more experienced instructors. <br><br>In Alberta, at least, aspirin can be administered to someone exhibiting the symptoms of a heart attack. If they have no medication, or if they've taken their medication and it has not been effective, we can administer 1 regular adult tablet (or 2 children's tablets, if you can still buy childrens' aspirin) - approximately 300 mg. They should chew it and let it dissolve in the mouth, not swallow it like they would for a headache.<br><br> The workbook says nothing about giving a second dose if the first tablet is not effective. I checked with one of the other instructors, who's also a trained paramedic; he says he would not give a second dose.<br><br>So the short answer would be: 1 regular adult tablet, chewed not swallowed, to be administered only after their prescription medication (if any) has been taken and been ineffective.<br><br>I would check with the Red Cross or some other agency about the regulations in your area. For example, in Alberta, I can administer aspirin (for a heart attack, not for a headache :-) - but an EMR couldn't, because the Alberta College of Paramedics would revoke their certification. (I'm just a lowly First Aid instructor, so I'm not registered with the College of Paramedics. :-)
