According to Japanese Researchers, placing of moveable defibrillators in public places such as schools and workplaces has helped people endure cardiac arrest.

In a study published in the New England Journal of Medicine, the researchers recommend that automated external defibrillators or AEDs, should be extensively available to the communities.

Defibrillators enable the heart to reinstate its normal rhythm. AEDS are handy and are planned to automatically study the heart's rhythm and direct the user to give a shock if required.

The researchers observed 12,631 Japanese adults who suffered cardiac arrest outside of a hospital in front of bystanders between 2005 and 2007.

Japan made it legal for any citizen to use an AED one year before beginning the study.

By and large, rate of survival after one month with minimal brain damage was 14.4%. The number of victims who got an AED shock from a passerby soared to 32% surviving with minor to no brain damage one month after their cardiac arrest.

Researchers recommend that the progress was due to onlookers who observed a collapse calling quickly for emergency assistance, inquiring where the AED was and using it.

Dr. Tetsuhisa Kitamura of the Kyoto University Health Service and Colleagues said, "The time from a patient's collapse to the initiation of CPR was reduced because of the increase in bystander-initiated CPR, and both early shock and early initiation of CPR contributed to a better outcome".
