Making Sense of Lung Function Tests: A hands‐on guide

Abstract

This is as an introductory text for physicians specialising in respiratory medicine. It helps trainee physicians to integrate understanding of the physiological principles underlying lung function with their interpretation in clinical practice. Pt. I. Tests of mechanical properties -- 1. Peak expiratory flow -- 2. Spirometry -- 3. Airway responsiveness testing -- 4. The flow volume loop -- 5. Static compliance -- 6. Lung volumes -- 7. Diffusion capacity -- 8. Respiratory muscle power -- 9. Airway resistance -- Pt. II. Blood gas interpretation -- 10. Assessment of ventilation -- 11. Assessment of oxygenation -- 12. Distribution of ventilation and perfusion -- 13. Assessment of haemoglobin saturation -- 14. Respiration and acid-base balance -- Pt. III. Exercise testing -- 15. Disability assessment tests -- 16. Limited exercise testing with saturation monitoring -- 17. Maximal cardiorespiratory testing -- Pt. IV. Characteristic patterns of abnormality by disease.
