Endotracheal tube in right main bronchus

Case contributed by Dr Derek Smith


Admitted with seizures and reduced GCS. CXR to confirm ETT position.

Patient Data

Age: 40 years
Gender: Female

Supine radiograph.

ETT tip projects over the right main bronchus. There is corresponding loss of the left hemidiaphragm, with volume loss and mediastinal shift to the left.

The lungs are otherwise clear.


ETT retracted slightly - approximately 20 minute interval

Compared with the earlier study, the ETT is now appropriately positioned approximately 2 cm above the carina. Re-expansion of the left lung - the diaphragm is now more visible. The mediastinal shift is also improving (the right cardiac shadow is now to the right of the vertebral bodies).

Case Discussion

This patient's ET tube is initially demonstrated down the right main bronchus, with subsequent left sided collapse.

This was recognised by the clinical team and fixed, with the second CXR showing better positioning and re-expansion of the left lung. This was only over a 20 minute interval and shows how quickly these changes can occur, and the importance of recognising tube and line positioning on acute studies.
