Angela Green from the East Kent Hospitals Trust explains how a group of bikers in Kent help save the NHS tens and thousands of pounds.
Riders from the SERV group deliver urgently- needed blood to hospitals.They're on call 365 days a year.
They also deliver blood to the Kent, Surrey and Sussex Air Ambulance. It means doctors and paramedics can carry out transfusions at the scene of an accident increasing someone's chance of survival. It's a procedure that's usually performed after a patient arrives at hospital.
