Evaluation of Diaphragmatic Ultrasonography as one of the Criteria of Discontinuation of Mechanical Ventilation

Abstract

The weaning process is a key element of mechanical ventilation, occupying up to 50% of its total duration. It is crucial to identify the right time to extubate a patient, since re-intubation after pre-term extubation is associated with an increased risk for nosocomial pneumonia, prolonged intensive care unit (ICU) stay and even death, and also accounts for substantially increased costs. Conversely, an unnecessary delay in extubating a patient who has successfully passed a weaning test may also increase morbidity and mortality due to complications associated with prolonged mechanical ventilation.
