Prestan Adult Professional Manikin is available individually or in multipack of four. They are realistic to the eye and touch, and uniquely designed as a clamshell which accommodates an easy-to-insert face shield/lung bag. The new CPR Rate Monitor gives instant feedback, accessible to both instructor and student. It allows students to measure their rate of compression and allowing the instructor to monitor several students quickly and easily. Patented face/head tilt simulates the way an actual head would move if CPR is required. Manikins incorporate a mechanism which allows usage of correct force to compress the chest to the correct depth.
