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.
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 Factors Affecting Lung Function
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
