Dr. Bruce Thompson leads the Physiology Service at the Lung Function Laboratory, testing over 7,000 patients annually. The laboratory conducts a range of assessments including simple spirometry, complex gas exchange measures, and cardiopulmonary exercise tests. With a dedicated team of 6.5 EFT, the lab emphasizes research and development while exploring critical factors affecting lung function like ventilatory capacity, gas exchange, and respiratory muscle strength. Dr. Thompson shares insights on career development, the application of scientific knowledge in respiratory physiology, and valuable advice for aspiring professionals.

Respiratory Physiologist Dr Bruce Thompson Head, Physiology Service
Lung function laboratory • Test in excess of 7000 patients/year. • Simple spirometry – Complex measures of gas exchange and cardiopulmonary exercise tests. • 6.5 EFT perform these tests plus other duties – eg research and development. • All the staff come from a physiology/ Medical physics background.
Factors Affecting Lung Function • Ventilatory function • Lung volumes & capacities • Diffusing capacity • Lung & chest compliance • Distribution of ventilation • Arterial blood gases • Pulmonary blood flow • Respiratory muscle strength • Control of ventilation No single lung function test measures all aspects of respiration
Common Respiratory Function Tests • Ventilatory function • Lung volume estimations: gas dilution body plethysmography • Gas transfer (TLCO) • Blood gas analysis • Bronchial provocation challenge: Methacholine, Histamine, Exercise, Hyperosmolar (saline) • Lung mechanics: compliance, conductance • Ventilatory responses to hypoxia and hypercapnia • Cardio-pulmonary exercise testing
What advice would I have like to have heard as an undergrad?
