Diaphragm Excursion-Time Index

The diaphragmatic response to increased mechanical load following withdrawal of mechanical ventilation is critical in determining the outcome of extubation. Using ultrasonography, we aimed to evaluate the performance of the excursion-time (E-T) index-a product of diaphragm excursion and inspiratory time, to predict the outcome of extubation.Right hemidiaphragm excursion, inspiratory time, and E-T index were measured by ultrasonography during...
