Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An ET tube terminates approximately 3 .1 cm above the carina in grossly appropriate location . An enteric tube is identified , with distal tip projecting below the lower limits of the radiograph , with the majority of the distal part coiling and projecting over the left upper abdomen , likely within the stomach . There is probable background hyperinflation / COPD . There is at least mild cardiomegaly , with enlargement of the cardiomediastinal silhouette . There are diffuse bilateral airspace opacities with a central predominance , along with interlobular septal thickening , consistent with pulmonary vascular congestion and moderately severe CHF . Retrocardiac opacity may represent atelectasis , however developing infection would be difficult to exclude . There is likely a small left pleural effusion . There is no right gross pleural effusion . No pneumothorax detected . Punctate density overlying the left neck raises the question of a small focus of left carotid artery calcification .
    OUTPUT:
    
1 . Probable background hyperinflation / COPD . 2 . Mild moderate cardiomegaly , with enlargement of the cardiomediastinal silhouette . 3 . Moderately severe CHF , probably with areas of pulmonary edema . Likely small left pleural effusion . 4 . Increased retrocardiac density , consistent with left lower lobe collapse and / or consolidation . 5 . ET tube and enteric tube nominal in position .
