Paramedic CU-ER2 is an easy to use defibrillator with AED and manual modes. In AED mode, it runs in the same way as the Paramedic CU-ER1. In manual mode, the user does the analysis of the victim’s ECG and sets the energy output of the device. The energy output may be set from 2 Joules to 200 Joules. It is intended for use by emergency first responders.
