Well, it is obvious that it has been a while since you have had a CPR class, because a heart attack can mimic flu like symptoms. It is better to have it checked out to do what we call in the business R/O MI.
Okay, so now he’s got diarrhea, influenza, pneumonia and he’s suffered a heart attack. This is getting good.
Ironically, I have my CPR class tomorrow. This morning, a vein in my left arm drank a bag of fluid (500 ml of lactated ringer's). This afternoon I became Combat LifeSaver (CLS) qualified.
