The Immobilizer Adjustable Cervical Collar is lightweight, strong and flexible yet easy to apply. It can be adjusted at 3 different positions (mini, mid, pedi) insuring the patient is always fitted correctly. The padded inner layer makes it comfortable for the patient. The collar includes a large posterior and anterior opening to allow the rescuer palpation of the spine as well as access to the tracheal and carotid areas. The Immobilizer Cervical Collar can easily be penetrated by X-ray, MRI, or Cat scans and is compatible with spine boards and other head immobilizers.
