According to a new research, there could be better chances of survival for one suffering from heart attack if a bystander tries to give artificial respiration to them at once. And the new thing is that it is not necessary to give the mouth-to-mouth CPR (cardiopulmonary resuscitation).

The study has been published in the Journal of the American Medicinal Association (Jama). It is possible to save one’s life by just doing chest compressions that help push blood throughout the body again.

According to lead researcher Dr. Carolina Malta Hansen, of the Duke Clinical Research Institute in Durham, NC, "During that time, survival with good brain function increased from 7 to 10 percent for those who received bystander CPR”. She added that those patients who received CPR from bystanders, or defibrillation from police or firefighters that were first responders, had more chances of survival.

According to Hansen, "Early intervention, whether it's by bystanders or first responders, is associated with increased survival compared to EMS [emergency medical services]".

The research was done using data gathered for over four years from 4,961 heart attacks in 11 North Carolina counties. Each county launched a campaign during this period and encouraged people to do chest compressions or make use of automated external defibrillators, when an ambulance is awaited.

On the whole, survival with good brain function rose by 37%. As per the study, the proportion of patients who received CPR (chest compressions) from bystanders rose from 39.3% to 49.4%. Approximately 11% of people who received CPR from bystanders were able to survive as compared to others who didn’t get immediate response of such kind.
