Key Learning Points
1. Chest X-ray anteroposterior (AP) films magnify the heart and mediastinum, and obscure the left lower zone.
2. When assessing the correct positioning of internal jugular central venous catheter placement, as a rule of thumb, the tip should lie at the level of the carina and to the right of the mediastinum.
3. When assessing the correct positioning of an endotracheal tube, the tip should lie 5–7 cm above the carina.
4. When assessing the lung fields, divide the lungs into three zones: upper, middle and lower thirds. Compare each side and check for asymmetry.
5. Consolidation refers to small airways and alveoli that are filled with material – pus, fluid, blood or cells. Consolidation is not synonymous with infection.
