    INPUT: Overall , there is no significant interval change in large left - sided airspace opacification consistent with pneumonia . A relative lucency in the left base likely represents a small amount of aerated lung adjacent to the consolidation . No definite pneumothorax is seen . There may be a small left pleural effusion . The heart size appears within normal limits . An endotracheal tube is in standard position . A right internal jugular central venous catheter tip reaches the upper SVC . An esophageal catheter is in place with tip in the stomach , however , side port likely within the distal esophagus or just at the gastroesophageal junction .
    OUTPUT:
    
1 . No significant change in extensive left - sided pneumonia . 2 . Esophageal catheter with tip in stomach , however , side port in distal esophagus or at the gastroesophageal junction and should be advanced to ensure side port is within the stomach .
