    INPUT: AP portable supine view of the chest . There has been interval intubation with the tip of the endotracheal tube residing approximately 3 .5 cm above the carina . Since the prior exam , there is increasing bilateral atelectasis and ill - defined opacities within the lungs , left greater than right , raising concern for interval aspiration . A component of mild edema is difficult to exclude . No supine evidence for large effusion or pneumothorax . Cardiomediastinal silhouette is grossly stable though difficult to assess given technique . No acute bony abnormalities .
    OUTPUT:
    
1 . Appropriately positioned endotracheal tube . 2 . Increasing opacities in the lungs likely reflect a combination of atelectasis and possible aspiration . Difficult to exclude mild edema .
