Every year, thousands of people in Sweden suffer cardiac arrest outside of hospital. The majority of victims are affected at home or in public places where medical personnel or defibrillators are rarely on site. In cases where CPR was started within 1 minute and a defibrillator was used within 5 minutes, 49-75 percent survival has been reported. For every minute, the person's chance of survival decreases by about 10 percent. In Sweden, the time from alarm to defibrillator is 10-60 minutes, which means that there must be someone who can freeze the time until medical personnel are on site. Are you one of them?
