If you are a bystander coming to the aid of someone going through cardiac arrest you might want to enlist the help of another Good Samaritan.

New research reveals the odds of survival are better when more than one person comes to the rescue.

What the researchers don't know is whether the helpful bystanders performed or even knew CPR, but hands-only CPR, which just involves chest compressions, can help victims until paramedics arrive.

What the Japanese study does show is that among the 5,000 adults who went into cardiac arrest, the odds of survival went up two fold higher when more than one person tried to help.
