More Rescuers Improve Out-of-Hospital Cardiac Arrest Outcomes
Researchers from Japan have found that more people to give help in the case of cardiac arrests out-of-hospital are better than one. Based on such factors The American Heart Association (AHA) and other groups have emphasized that everyone must have to learn the cardiopulmonary resuscitation (CPR).
Cardiac arrest is a pathological condition in which the electrical impulses in the heart get disturbed as a result heart becomes unable to pump blood and oxygen to the rest of the body. It could be deadly within minutes, if left untreated. CPR can help in the flow of blood and oxygen until medical help reaches, which can use defibrillator to reverse cardiac arrest by generating electrical shock.
Researchers, in this study, have found that among 5,078 adults, who got cardiac arrest out-of-hospital, those adults, who were helped by more than one person, had two-times more chances of survival than the other adults. Researchers have reported that when three or more rescuers came to help the patient of cardiac arrest, 6% of victims were alive one year later, while only 3% of victims remained alive when there was only one person was present near them to help. This percentage is at 4, when the victims were rescued by two people.
Researchers have noted that the reason for increased chances of survival increase as some people may have tried in some way that could be better than others.
"This study confirms the importance of bystanders responding to cardiac arrest, and the importance of early CPR," Dr. Michael Sayre, an associate professor of emergency medicine at Ohio State University in Columbus and a spokesman for the AHA told Reuters Health.
However, as a paradox, researchers have found that the presence of many rescuers at home, where cardiac arrests of elderly and frail people are more likely to occur, has no survival advantage and the reason for this is not clear.
This research has been published online in the journal Resuscitation.
