Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable AP chest radiograph is obtained . Right IJ central venous catheter terminates in the lower SVC . Heart size can not be acurately assessed from the AP projection . Cardiomediastinal contours are unremarkable . Lung volumes are low . Uniform opacification of the right base with loss of right hemidiaphragm and right heart border likely reflects lower lobe collapse , but consolidation can not be excluded . There is no evidence of pulmonary vascular congestion . Small right pleural effusions are possible . Linear atelectasis is seen within the left base . No pneumothorax .
    OUTPUT:
    
1 . Left basilar opacification likely reflects volume loss and right lower lobe collapse , but consolidation can not be excluded . 2 . No evidence of pulmonary vascular congestion or fluid overload .
