Interface pressure measurements during ambulance journeys

This study investigated the risk of developing pressure damage associated with surfaces used in ambulances. One subject's journey in an ambulance was evaluated to identify the intensity of interface pressures (in mmHg) at particularly susceptible areas (the ischial tuberosities, sacrum and heels) while the vehicle was both stationary and moving. Interface pressures measured on a standard ambulance stretcher and a spinal board were also compared. Results indicate that the pressure readings obtained are likely to lead to capillary occlusion with the potential development of pressure damage. Manufacturers of ambulances therefore need to consider incorporating pressure-relieving surfaces in seats and stretchers in the future.
