What is the purpose of using a C-collar in trauma cases?

Using a cervical collar, or C-collar, in trauma cases primarily serves to stabilize the cervical spine and prevent further injury. In situations involving potential spinal injuries, such as motor vehicle collisions or falls, the neck and head are particularly vulnerable. Properly applying a C-collar minimizes motion of the cervical spine, which can help safeguard against exacerbating any existing injuries.

The design of the C-collar restricts head and neck movement, providing support and alignment, which is crucial for preventing damage to the spinal cord. If a patient has a fracture or other injury to the cervical spine, unnecessary movement could lead to severe complications, including paralysis.

The other options focus on different interventions that do not align with the specific purpose of the C-collar. For instance, providing oxygen is essential in trauma care, but this is typically addressed through airway management rather than the use of a C-collar. Immobilizing limbs may be necessary but is separate from the function of the C-collar, which is specifically designed for the neck region. While assisting in patient transport to the hospital is an important part of emergency care, it is not the direct function of the C-collar itself.
