A visitor named Lewy sent in a link to this ABC News story
about 'Cough CPR' following up on my post about the subject below. It turns out that a Polish researcher, Dr. Tadeusz Petelenz, published some results just a few weeks ago suggesting that vigorous coughing could help people experiencing cardiac arrest remain conscious long enough to get help. But the jury still seems to be out on the subject. The UK Resuscitation Council
says that there's no evidence coughing is going to help. The basic problem is that if you do the cough CPR, you've got to time the coughs exactly right, or you could actually make the heart attack worse. An emergency nurse named Richard Muth has written a good summary
of the few instances when coughing actually CAN be helpful for heart problems (they all involve being in a hospital).
