The situation: you are by yourself, and you begin to have severe chest pain, followed by acute vertigo. You are having a heart attack, and moments later you feel like you are about to faint. With a few seconds left before you lose consciousness, what do you do?

In truth, you should dial 911 on your cell phone. But after that… cough, deeply and forecefully, about once every 1 to 3 seconds. Long derailed as a hype product of the devious “world-wide web,” improvised ‘cough CPR’ may actually have some merit, according to some cardiovascular researchers. The idea of coughing to sustain arterial pressure and to induce blood flow first appeared in the Journal of the American Medical Association in 19761. Therein, the authors purported that coughing during ventricular fibrillation not only kept several patients conscious for up to 39 seconds after the onset of VF, but that coughing maintained arterial pressure at almost 140mmHg, compared to only 60mmHg for traditional chest compressions. That is, they indicated that ‘cough-CPR’ could have advantages over normal CPR.

And while the American Heart Association, formally and adamantly, does not endorse the maneuver2, scientists continue to demonstrate that coughing during a heart attack can actually help blood circulate. The picture below shows the EKG Read the rest of this entry »
