PRESTAN Professional Adult CPR/AED Training Manikin with CPR Monitor – Realistic to the eye and the touch, the PRESTAN Adult Professional Manikin is unlike any other on the market. PRESTAN manikins are uniquely designed as a clamshell – accommodating an easy-to-insert face shield/lung bag. PRESTAN’s revolutionary new CPR Rate Monitor allows for real time feedback to both instructor and student regarding the frequency of chest compressions. This allows each student to gauge their frequency of compressions on their own as well as allowing the instructor to monitor several students quickly and easily. With PRESTAN’s patented face/head tilt functionality, the PRESTAN Professional Adult Manikin simulates the manner in which an actual victim’s head would move if he required CPR. In addition, the unique construction of our manikins incorporates a mechanism to help them use the correct force to compress the chest to the correct depth.
