Review age, gender, smoking status, BMI, indication, flow-volume curves. Quality control. Three acceptable maneuvers with repeatable values: Two highest values of FVC and FEV1 should be within 150mL (100mL if FVC ≤ 1L)

Describe the clinical indications for pulmonary function testing. Understand the physiology of the core pulmonary function tests: spirometry, lung volumes and DLCO. Apply an organized approach to interpreting pulmonary function tests.
LUNG VOLUMES & CAPACITIES: Tidal Volume (VT):The volume of air entering the nose or mouth per breath (500 ml). Residual Volume (RV): The volume of air left in the lungs after a maximal forced expiration (1.5L). Expiratory Reserve Volume (ERV): The volume of air that is expelled from the lung during a maximal forced expiration that
Interpreting results. Best of 3 consistent readings (FEV1 & FVC) Borderline normal results - repeat in few months to confirm diagnosis (especially > 75 years) Abnormality detected if any of following recorded: FEV1 <80% predicted normal. FVC <80% predicted normal.
The first three editions of Interpretation of Pulmonary Function Tests were well received and met our goal of appealing to a wide, varied audience of health professionals.
