Description Physio-Control LIFEPAK CR2 AED Trainer by Physio-Control. This trainer resembles the Physio-Control LIFEPAK CR2 in form and function. This is a non-shocking AED training device. The LIFEPAK CR2 AED Trainer comes with one pair of adult/child training electrodes. It uses the same voice prompts and CPR coaching verbiage as the live CR2 AED. The trainer can simulate both semi-automatic and fully-automatic options, and provides live feedback for CPR rate, depth, and hand placement. The volume adjusts automatically depending on background noise, and training scenarios are controllable from the LCD panel located under the electrode tray.
