What is the normal position of the trachea on a chest x-ray?
Central to slightly to the right.
What is the significance of tracheal shift?

Homogeneous opacification of the right lung with the trachea pulled to the right side.
The cardiac shadow is not visualised as it is silhouetting with the opacified hemithorax due to mediastinal shift to the right side.
