    INPUT: Endotracheal tube tip terminates approximately 4 .9 cm from the carina . Lung volumes are low compared to the prior study . This accentuates the cardiomediastinal silhouette size which appears borderline enlarged . Crowding of bronchovascular structures is present without overt pulmonary edema . Hazy and patchy bibasilar opacities likely reflect atelectasis . No pleural effusion or pneumothorax is present . No acute osseous abnormality is seen . Clips are seen within the neck bilaterally compatible with recent thyroidectomy .
    OUTPUT:
    
Endotracheal tube in standard position . Low lung volumes with bibasilar atelectasis .
