compare and evaluate the effect of use of ultrasonic criteria of weaning versus the conventional ways of weaning in post-traumatic acute respiratory distress syndrome (ARDS) patients who were ventilated for a long time. And compare their effect on the duration of ICU stay.

It is a prospective double blind study done on total 200 patients. Who were weaned from ventilator after being ventilated for > one week due to respiratory failure. This respiratory failure was selected in our study to be from severe lung contusion and post-traumatic acute respiratory distress syndrome. Patients were randomly allocated in one of two groups each group contain 100 patients. Group A considered control group. Those patients weaned from the ventilator by the conventional criteria of weaning. While group B weaned from the ventilator by the ultrasound criteria of weaning. All patients weaned from both groups followed for six days for signs of failure of weaning ,signs of post-extubation respiratory failure. And number of patients who were re-ventilated and who discharged from ICU in both groups recorded and compared.

Inclusion Criteria:

• adult patients between 18-65 years old,
• with Acute respiratory distress syndrome,
• any ventilated patients for more than one week

Exclusion Criteria:

• young or pediatric patients below 18 years.
• patients older than 65 years
• patients had Chronic Respiratory Disease

both sex are allocated randomly in one of the two groups
