What is the primary function of a cervical collar?

The primary function of a cervical collar is to stabilize the neck. It is designed to minimize movement in the cervical spine, particularly in cases of suspected injuries, such as cervical fractures or spinal cord injuries. By limiting motion, a cervical collar helps prevent further injury while providing necessary support, particularly during transport.

While a cervical collar may have secondary benefits that could relate to the stabilization of the back or spine, its main purpose is to specifically maintain the alignment and stability of the neck area. This is crucial in emergency situations, where any movement of the neck could exacerbate an injury. Other options, such as preventing head movement or providing thermal protection, are not the primary roles of a cervical collar, as its primary objective is focused on neck stabilization to safeguard the patient's condition.
