What will be the effect on spirometry in case of lobectomy done for bronchogenic carcinoma?
Correct Answer: Increased dead space ventilation
Description: In case of lobectomy, since the remaining lung tissue is lesser, all parameters like vital capacity, residual volume and closing volume will reduce. Hence, due to hypoxic stimulus post-operative patients of lobectomy will take rapid shallow breaths. This will lead to increased Dead space ventilation.
