Added minutes while trying to resuscitate a person suffering from heart attack can lead to his survival, revealed a study, which has been published in the Lancet medical journal. The study seems to be contradicting previous studies, which have rejected any such claims.

The study was taken out by a group of researchers from University of Washington. In order to reach at the above given conclusion, the study researchers being led by Zachary Goldberger looked at US hospital records of patients, who have suffered cardiac arrest.

Main aim was to check the revival efforts being made by the hospital staff. To know the same, they have assessed 64,000 patients from 435 hospitals across the US from 2000 to 2008.

Assessment reports revealed that on an average, doctors have tried 20 minutes to revive a person. It has also been revealed that 25 minutes was the longest time period and 16 minutes was the shortest time period being spent on patients to revive their heart beat.

Doctors said that there was a 12% increased chance of survival when they tried for 25 minutes. "To improve outcomes, all hospitals should audit their cardiac arrests and benchmark outcomes as part of a quality improvement program", said study researchers.
