Prediction of Successful Liberation From Invasive Mechanical Ventilation Via Lung and Diaphragmatic Ultrasound in Intensive Care Unit Patients, Prospective, Observational Study

While the patient in a semi-sitting position (20-40 degree), by ultrasound, the diaphragm thickness was measured in the zone of apposition, on the mid-axillary line among the 8th and 10th intercostal spaces, using a 7-10 MHz linear probe in (M) mode. at the end of expiration and at the end of inspiration by capturing nearly three images during spontaneous patient breathing. The average of three DTI measurements was calculated In lung ultrasound, 2-4 MHz convex ultrasound probe in (B) mode was employed. We implemented a modified LUSm in our investigation, which assessed four lung regions on each side.
