Interval extubation . Nasogastric tube seen coursing below the diaphragm with the tip not identified . Lung volumes are diminished with streaky opacities at both bases suggestive of atelectasis or aspiration and crowding of the pulmonary vasculature which may reflect a component of superimposed edema . More focal faint opacity in the right upper lobe also could reflect an area of atelectasis or be related to edema . Clinical correlation is advised . Overall cardiac and mediastinal contours are likely unchanged given differences in positioning . No large pneumothorax .
