If the appropriate size cervical collar is unavailable, what should you do?

Using rolled towels to immobilize the patient's head is an acceptable alternative when the appropriate size cervical collar is unavailable. This method can help create a makeshift support that limits the movement of the cervical spine, which is crucial in cases where spinal injury is suspected. By positioning the rolled towels snugly around the neck and securing the head, you are helping to stabilize the patient's head and neck, minimizing the risk of any further injury during movement or transport.

This approach is particularly useful in emergency situations where immediate immobilization is necessary but suitable equipment is not on hand. It reflects a resourcefulness in providing care while adhering to the principles of spinal precautions. Other methods may not provide adequate stabilization or could be unsafe for the patient.
