Cough CPR is the subject of a hoax email that began circulating in 1999. Please avoid spreading this myth any further.

Dr. Richard O. Cummins, Seattle's director of emergency cardiac care, explains that cough CPR raises the pressure in the chest just enough to maintain some circulation of oxygen-containing blood and help enough get to the brain to maintain consciousness for a prolonged period. But cough CPR should be used only by a person about to lose consciousness, an indication of cardiac arrest, he cautions. It can be dangerous for someone having a heart attack that does not result in cardiac arrest. Such a person should call for help and then sit quietly until help arrives, he says.
In other words, the procedure might be the right thing to attempt or it might be the very thing that would kill the afflicted depending on which sort of cardiac crisis is being experienced. Without a doctor there to judge the situation and, if cough CPR is indicated, to supervise the rhythmic coughing, the procedure is just far too risky for a layman to attempt.
Forget about coughing — key to surviving a heart attack is obtaining proper medical assistance within a very limited window of opportunity. Once an acute myocardial infarction (AMI) has been diagnosed, speedy injection of thrombolytic agents to dissolve clots is of the utmost importance — the more quickly those drugs are delivered, the better the chances of survival are. It's a race against the clock.
