Diaphragm Training Ultrasound

inspiratory muscle training (IMT) will be initiated starting from the first ICU day. IMT will be conducted for 10 minutes two sessions per day, with an initial load of 30% of the maximum inspiratory pressure (MIP) measured immediately after changing patients to pressure support mode, and increased up to 40% in the second 5 minutes if tolerated by the patient. In addition, these patients received the usual care of MV patients.
