Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube terminates approximately 5 cm above the carinal . An orogastric tube is difficult to follow due to underpenetration but apparently proceeds into the stomach . Within the limitations of AP portable technique with low lung volumes , the cardiac , mediastinal and hilar contours are probably within normal limits . Vague hazy opacity in the left costophrenic cysts angle may indicate atelectasis , perhaps trace effusion . Otherwise , lung fields appear clear . There is no evidence of pleural effusion on the right side .
    OUTPUT:
    
Status post endotracheal intubation . Perhaps trace pleural effusion or atelectasis on the left , but generally speaking , clear lungs .
