The LIFEPAK CR Plus AED by Physio-Control, a division of Medtronic, is an AED for everyone. With its easy to activate lid requiring no on/off button to push, this AED is ready to go. It is compact in size, weighing only 4.5 lbs with CHARGE-PAK™ and electrodes. It offers escalating energy ranging from 200J to 360J and is available in both a semi-automatic model with a shock button and a fully-automatic model that does not require the rescuer to press any button. A fully charged device has a typical capacity of 30 full discharges or 210 minutes of "on time". The AED guides the rescuer with ClearVoice™ technology step by step voice prompts. The electrode pads and CHARGE-PAK™ come with the same expiration date to keep things simple. Available in either semi-automatic or fully-automatic.
