Final chest radiograph. A final chest radiograph shows that pneumothoraces are not present. The imaging study continues to reveal persistent bilateral opacities (red arrows) as before, consistent with acute respiratory distress syndrome. A 20 French extracorporeal membrane oxygenation catheter is shown (yellow arrows) over the right lung field, terminating in the right atrium. The patient’s airway is patent, and is demonstrated by the dark blue arrow.
