Lung volumes are low with obscuration of the lung bases bilaterally , a combination of pleural effusion and atelectasis . Heart size is similar . There is new pulmonary vascular congestion and moderate interstitial edema .
    OUTPUT:
    
Pulmonary vascular congestion and interstitial edema has increased , as have apparent bilateral pleural effusions , however this may be secondary to supine positioning .
