Washington: Increasing the time spent administering CPR to cardiac arrest patients won`t increase their chances of survival, researchers said, putting to rest one of the raging debates in emergency medicine."Our study definitively shows that there is no advantage to a longer period of initial CPR," said Dr Ian Stiell, a senior scientist at the Ottawa Hospital Research Institute (OHRI), one of the entities leading the study.Paramedics and firefighters traditionally have provided only brief CPR while readying a defibrillator to jolt the heart into restarting.But some experts over the years have said that a longer period of initial cardio-pulmonary resuscitation -- for up to three minutes -- may help increase a cardiac arrest patient`s odds of survival.
