Realistic to the eye and the touch, the Prestan Professional Infant Manikin is unlike any other on the market. Their revolutionary CPR Rate Monitors allow for instant feedback to both instructor and student regarding the rate of chest compression. This allows each student to gauge their rate of compressions on their own as well as allowing the instructor to monitor several students quickly and easily. And with the patented face/head tilt, the Prestan Professional Infant Manikin simulates the way an actual victim's head would move if he required CPR. In addition, the unique construction of the manikins incorporates a mechanism to help students use the correct force to compress the chest to the correct depth.
