Malpositioned ET tube

In this example of a malpositioned endotracheal tube, the tip of the tube is well down the right main bronchus (arrow). In addition to causing hypoventilation of the left lung, when in this location the wall of the tube can potentially occlude the origin of the right upper lobe bronchus, meaning that only the right middle and lower lobes are ventilated. In this case there is also extensive consolidation in both lungs, more confluent in the left base, and there are bilateral pleural effusions. Note the left IJ venous line.
