Final answer:
The Kendrick Extrication Device is used in emergency care to safely extricate and immobilize patients suspected of having spinal injuries from confined spaces.
Step-by-step explanation:
The Kendrick Extrication Device (KED) is primarily used in pre-hospital emergency care environments for the safe extrication of individuals from motor vehicle accidents or other confined spaces where spine injuries are suspected. The KED is designed to provide rigid support to the head, neck, and back during the process of extrication, thereby minimizing the risk of further injury by immobilizing the spine. It wraps securely around the patient's torso and head and allows for the patient to be safely moved to a stretcher or other transport device.
