EVALUATION OF THE ENERGY RELEASED BY A DEFIBRILLATOR FROM THE PERSPECTIVE OF CLINICAL ENGINEERING

Abstract

Electro-Medical Equipment’s (EMEs) are an important instrument for intervention in medical institutions of Brazil. This article aims to estimate the level of reliability in the operation of certain defibrillation equipment used in Hospital das Forças Armadas (HFA), located in Brasília (Brasil), specially regarding the energy released, and also, to evaluate measurement uncertainty. The equipment used for the tests was the Defibrillator Analyzer DNI Nevada, Impulse 3000 model and serial number 3347, and it was used for collecting data of released energy. The collected data were organized into spreadsheets and processed graphically, the selected pattern energy were of 10, 100 and 200 Joules (J), namely, five repetitions for each chosen energy. The measuring uncertainty analysis of the defibrillators were done by means of a normative metrological test that uses statistic results and which certifies the adequacy of EEMs to security and ABNT and manufacturer standards. By quality standards, both compliance and prospect of Clinical Engineering (CE). The results found the average, standard deviation, accuracy uncertainty, measurement uncertainty and combined standard uncertainty, among others, which served to review and completion of uncertainty and measurement.
