The role of diaphragmatic rapid shallow breathing index as a predictor of weaning from mechanical ventilation using transdiaphragmatic ultrasonography

Abstract

inimizing the duration of mechanical ventilation (MV) is of a paramount importance for all critical care physicians. Therefore, deciding the appropriate time of weaning from MV is crucial, as delayed weaning and extubation is associated with longer intensive care unit (ICU) stay, inappropriate utilization of health care resources, and greater morbidity and mortality. Although rates of weaning and extubation failure differ considerably among ICUs, approximately 15% of patients in whom mechanical ventilation is discontinued require reintubation within 48 hours. Consequently, it is fundamental for critical care physicians to differentiate between readiness for discontinuation of ventilation and successful spontaneous breathing trials.
