FINDINGS:
AP single view of the chest has been obtained with patient in
 semi-upright position.  Comparison is made with the next preceding supine
 chest examination of .  The patient was intubated and has now
 received a tracheostomy cannula which is seen to be in correct intratracheal
 position with the tube lower point terminating some 3 cm above the level of
 the carina.  No pneumothorax has developed.  A previously existing left
 subclavian approach central venous line remains in unchanged position.  Also,
 a previously existing NG tube remains in unchanged position terminating in the
 lower abdomen, probably in the expanded fundus of the stomach.  No new
 pulmonary parenchymal infiltrates can be identified in comparison with the
 next preceding portable chest examination.  No pneumothorax has developed.
