    OUTPUT:
    
Diffuse bilateral airspace disease , similar to earlier the same day , though some interval increase in the opacity at the right base laterally appears to be present . As suggested on the recently obtained chest CT , this appears to represent an combination of background pulmonary nodules with new superimposed parenchymal opacities , raising the question of multifocal pneumonia or diffuse aspiration . In the appropriate clinical setting , hemorrhage might also account for this appearance . The CT also suggested an element of pulmonary edema . Lines and tubes as described . The right IJ central line tip overlies the upper right atrium . If clinically indicated , this could be retracted by approximately 1 .5 cm . No pneumothorax detected .
