title: [Defining characteristics of the dysfunctional ventilatory weaning response as indicators of accuracy of ventilatory weaning].
abstract: The study aimed to analyze the defining characteristics of the Dysfunctional Ventilatory Weaning Response as an indicator of the accuracy of ventilatory weaning. Observational study of 38 events of ventilatory weaning in adult patients admitted to intensive care. For the defining characteristics, it was calculated: sensitivity, specificity, positive and negative predictive values, accuracy or efficiency, likelihood ratio positive and negative, and diagnostic odds ratio. It was also considered the median number of defining characteristics in the event of success and failure. It was considered accurate: agitation, deterioration in arterial blood gases from baseline parameters, moderate use of accessory muscles of respiration, increased respiratory rate from baseline parameters and respiratory rate increases significantly with respect to baseline parameters. There was statistical difference in the median number of defining characteristics observed. It was concluded that the defining characteristic and the number of them would influence the success of the weaning decision.
