Chicago- A new resuscitation technique, which involves a round of two hundred chest compressions prior to a defibrillator shock, can increase the survival rate of persons when they experience a cardiac arrest, U.S. researchers reported on Tuesday.

In Arizona, rescue teams who employed the new technique of resuscitation on people who have had a cardiac arrest outside the hospital saw the survival rate triple when compared to that of the standard approach.

“Cardiac arrest is extremely common but the survival rate is very low,” said Dr. Bentley Bobrow, whose study was published in the Journal of the American Medical Association.

The new study was conducted in two cities in Arizona and it included 2,460 persons who had cardiac arrest outside of the hospital. About 1,799 people received treatment before the emergency personnel got trained in the new technique, which is named as minimally interrupted cardiac resuscitation (MIRC).

The new resuscitation procedure increases blood flow to the brain and heart when the heart stops functioning and it is not intended for onlookers.

“Though you could increase survival only by a small percentage, thousands of people can be across the country,” said Bobrow, medical director for emergency services, state of Arizona. Dr. Bentley Bobrow is also a researcher at the Mayo Clinic in Scottsdale.

Many experts say the most important thing for bystanders is to give chest compressions when waiting for an ambulance to arrive.

Cardiac arrest results when the heart stops pumping blood. People who have cardiac arrest have a kind of heart rhythm in which the heart shakes, does not circulate blood and it is called as ventricular fibrillation.

If shock is not given in the initial 4 minutes of this fatal rhythm, the heart stops completely and it is much difficult to get it work again. In this crucial phase, the traditional chest compressions can come handy in pushing blood back into the heart and making it more probable to start working again.

As most of the time emergency teams fail to arrive at the scene within the critical initial 4 minutes, the new approach requests for a round of two hundred chest compressions to be given in the initial 2 minutes so that the chances that the heart will restart. It would be a new help for the cardiac patients to help them at the need of any emergency.
