The adjustable Cervical Collar is actually four adult extrication collars in one. It adjusts to four adult sizes: Tall, Regular, Short, and No-Neck. The sizing method is fast and easy with indicator ovals and locking tab. The sizing versatility helps rescuers have the appropriate collar on hand to fit the patient and reduces inventory and storage space requirements. Designed for pre-hospital care, this collar features a large tracheal opening to permit easy access for pulse checks and advanced airway procedures. The rear panel opening allows C-spine palpation. The collar stores flat to save space.
