Your chances of surviving a cardiac arrest while out on the high street are slim. It's estimated survival rates decrease by ten percent for every minute you don't get medical help. The nearest ambulance may be on its way but could take several minutes to arrive. But what if an off-duty paramedic was just around the corner and could help out?

Nick Holland investigates whether it works work and what difference it could make to survival rates?
