Comparison of Weaning Parameters and Diaphragm Thickness Changes

On the day of hospitalization or the first day of mechanical ventilation, the patient's position was elevated by 30°, and the high-frequency linear probe of the ultrasound was placed perpendicular to the skin in the cranio-caudal direction, and the diaphragm apposition zone, where the right anterior and middle axillary line corresponds to the 8th-10th intercostal space, was imaged and measurements were made with B mode.
