Calibration Standard for Impulse Energy of Defibrillator and Defibrillator Analyzer

Impulse energy is one of the most important parameters that need to be calibrated for defibrillator and defibrillator analyzer. The measurement accuracy of commercial defibrillator analyzer could reach ± 1 % of reading plus 0.1 Joule nowadays. So, it placed a greater demand on the measurement standard used for the calibration. In the National Institute of Metrology (NIM) China, we had developed a set of national measurement standard. The calibration uncertainty on the defibrillator analyzer is evaluated to be better than 0.06% of reading plus 0.06 Joule. In this manuscript, the components of the system and the uncertainty evaluation of the measurement standard is introduced.
