What are the indications for applying a Kendrick Extraction Device (KED)?

The Kendrick Extraction Device (KED) is specifically designed to immobilize and facilitate the safe extraction of a patient from a vehicle, especially in situations where spinal injuries are suspected. This device is particularly valuable in scenarios where there is concern about the patient's spine, especially when there may not be sufficient personnel or space to perform a full spinal immobilization with a backboard.

In cases where a patient is trapped in a vehicle, the KED allows emergency responders to stabilize the spine and immobilize the patient while extraction occurs, minimizing the risk of further injury during the rescue process. Its design supports the torso and secures the patient's head, effectively maintaining spinal alignment.

While chest pain and shortness of breath, injuries to the leg, and fractured ribs can all be serious conditions requiring medical attention, they do not necessarily indicate the use of a KED for spinal immobilization and extraction. The KED's primary function is to address spinal concerns in confined spaces or situations where immediate full-spinal immobilization may be challenging. This makes option C the most appropriate choice regarding the specific indications for employing a Kendrick Extraction Device.
