What is the purpose of a 'c-collar' in trauma care?

The purpose of a cervical collar, commonly referred to as a 'c-collar', is to immobilize the cervical spine and prevent movement during transport. This is crucial in trauma care, particularly when there is a risk of spinal cord injury. By stabilizing the head and neck, a c-collar helps maintain alignment of the cervical spine, reducing the chances of exacerbating any existing injuries.

In situations where trauma has occurred, particularly in incidents like motor vehicle accidents or falls, the possibility of a cervical spine injury is significant. If a patient moves their head or neck during transportation, it could cause further damage or complications, potentially leading to paralysis or other severe neurological deficits. Therefore, the c-collar plays an essential role in pre-hospital care and initial management, aiding in the protection of the spinal cord.

The other options presented address different aspects of trauma care but do not specifically encompass the primary function of a c-collar. Supporting the head and neck, assisting with breathing, or applying pressure to bleeding wounds may be relevant in trauma situations, but they are not the main purposes of the c-collar.
