Item Métodos para la calibración de desfibriladores: una revisión(Universidad Santiago de Cali, 2020) Ruiz Aguayo, Jefferson; Delgadillo Barbosa, Fabián Camilo; Bermeo Varón, Leonardo AntonioThe defibrillator is a biomedical device that generates an electrical impulse through external electrodes located on the chest, or internal paddles directly to the heart, to reverse cardiac arrhythmias, ventricular fibrillation, ventricular tachycardia, atrial flutter, and supraventricular tachycardia, mainly. The good functioning of this equipment is of vital importance where the calibration takes a determining role in the use of the equipment to avoid adverse events. The calibration process of a defibrillator consists of comparing the quantities with the analyzer. Currently, there are several defibrillator calibration methods, where health institutions and metrological laboratories do not have the resources to define the most appropriate method, implementing the one that best suits their needs. In this paper, calibration methods are described, and, through a systematic study, standardization of a method is suggested, considering all its uncertainties and parameters. A review of the defibrillator calibration methods is carried out in databases such as Dialnet, Scielo, Science Direct, Google Academic, texts and theses from different international and national universities, finding 15 articles in a period from 2005 to 2019. The results indicate that the method proposed by Llamosa, Meza & Villareal is the most complete because it takes all the uncertainties that affect the measurement, such as the accuracy of the work pattern, resolution of the work pattern, resolution of equipment to be calibrated and repeatability of readings. It is recommended to change the 4000 analyzers to the 7000DP because the accuracy of the 4000 analyzers has high values that reduce the reliability of the method.
