What type of changes have been made in ambulance designs?

CPR seats and bench seats were standard configurations for decades, but crash tests by NIOSH demonstrates that both are unsafe to the provider.

Ambulances are now available with a configuration that enables an EMS provider to care for the patient, communicate with the hospital, and reach essential supplies and equipment while safely seated and restrained.

The manners in which cots/litters are secured in a vehicle have changed from the traditional antler mount to a track mount. Many ambulances also have power assisted cots that may help reduce back injuries to EMS providers.
