    INPUT: The patient remains intubated , the endotracheal tube is now approximately 5 cm above the level the carina . A nasoenteric tube is incompletely visualized , the tip lies below the left diaphragm . Lung volumes are unchanged . There are diffuse bilateral hazy airspace opacities , slightly improved when compared to the prior study . As previously this could reflect pulmonary contusion , aspiration and / or atelectasis . No definite effusion seen but the left costophrenic angle is not visualized . No pneumothorax . No rib fracture seen .
    OUTPUT:
    
Slight interval improvement in the bilateral hazy airspace opacities which again may reflect pulmonary contusions , atelectasis and / or aspiration .
