Validity of Lung Ultrasound in Diagnosis of Acute Respiratory Distress Syndrome

Validity of Lung Ultrasound in Diagnosis of Acute Respiratory Distress Syndrome and Prediction of Successful Weaning From Mechanical Ventilation in Those Patients

To evaluate the validity of lung ultrasound compared to CT chest and chest radiograph for diagnosis of ARDS and prediction of successful weaning from mechanical ventilation in those patients compared to traditional methods.

57 patients will be diagnosed as ARDS by CT chest and clinical criteria, then will be compared between the findings by lung ultrasound and chest radiograph to detect the sensitivity of both imaging to CT chest as gold standard in diagnosis of ARDS patients

Inclusion Criteria:

Patients or legal guardian's consent .All patients with suspicious criteria of acute respiratory distress syndrome .Hemodynamically stable in the absence or minimal of vasopressors.

Exclusion Criteria:

Pregnant women. patients with traumatic lung injury or pneumothorax. surgical dressings over the right lower rib cage which would preclude ultrasound examination. presence of ascites. presence of lung collapse, fibrosis, or pleural effusion.

-presence of any mass or mechanical factor in the chest or the abdomen interfering with the diaphragmatic mobility.
