Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable frontal chest radiograph demonstrates a nasoenteric tube that extends at least into the stomach . Even given low lung volumes , which lead to increased vascular crowding , there appears to be increased pulmonary edema and probably bibasilar atelectasis . In the appropriate clinical setting , superimposed pneumonia would be difficult to exclude but is not worse than before . Moderate to severe cardiomegaly is unchanged . Small bilateral pleural effusions persist . There is no pneumothorax .
    OUTPUT:
    
Increased pulmonary edema and probably bibasilar atelectasis . In the appropriate clinical setting , superimposed pneumonia would be difficult to exclude , but there is no definite worsened pneumonia .
