What is a key respiratory consideration with Trendelenburg position?

Explanation:
Tilting the patient head-down increases intra-abdominal pressure and pushes the diaphragm upward, which limits how much the chest can expand. This reduces lung volumes, especially functional residual capacity, and makes the chest wall stiffer to move. As a result, breathing requires more work and ventilation can become less efficient. This is why respiratory effort is increased in Trendelenburg, particularly in individuals with preexisting lung issues or obesity.
