    INPUT: The left - sided indwelling catheter is again noted , tip over SVC / RA junction . A Dobbhoff type tube is present , tip overlying gastric fundus . Note is made that a portion of the Dobbhoff tube is not visualized as it extends below the inferior edge of the film . No pneumothorax is detected . Mild cardiomegaly is similar to prior . There is upper zone redistribution with vascular blurring , consistent with CHF . There is a layering hazy opacity at right base that likely reflects a layering small pleural effusion with mild underlying collapse and / or consolidation . Aside from minimal atelectasis and equivocal minimal blunting left costophrenic angle , the left base grossly clear . No free air detected beneath the diaphragm .
