What is the function of C-collars in emergency situations?

The function of C-collars, also known as cervical collars, in emergency situations is primarily to immobilize the neck and spine. When a person has suffered a potential spinal injury, it is crucial to prevent any movement that could aggravate the injury or lead to further damage. The C-collar stabilizes the cervical spine by providing support around the neck, which helps protect the spinal cord from potential harm during transport or movement. This immobilization allows medical responders to safely assess and treat the patient while minimizing the risk of exacerbating any injuries.

The other options do not accurately describe the purpose of C-collars. For example, C-collars are not used to provide oxygen, secure medical supplies, or directly assess patient vitals, even though they play a significant role in the overall management of trauma patients. By focusing on immobilization, C-collars help maintain patient safety and facilitate proper care in emergency situations.
