Each year approximately 3500 Danes get a cardiac arrest outside the hospital. In two out of three cases first responders perform lifesaving first aid. The bystander to an out of hospital cardiac arrest is a crucial first responder of the ’chain of survival’ that can save lives. This exhibition project tells the personal story of 15 people who all responded when it really mattered. In a split second they had to make the decision: Do I respond or do I watch and do nothing? This project was done for TrygFonden - see the case here.
