28 Αυγ 2023 · Pulmonary function tests (PFTs) allow physicians to evaluate the respiratory function of their patients in many clinical situations and when there are risk factors for lung disease, occupational exposures, and pulmonary toxicity.
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.
Physicians can use the following stepwise approach to not only interpret PFTs from their office or a pulmonary function labora-tory, but also determine when to order fur-ther testing and...
Three acceptable maneuvers with repeatable values: Two highest values of FVC and FEV1 should be within 150mL (100mL if FVC ≤ 1L) Good start (back extrapolation < 5% of FVC or 150 mL) No cough or artifact in initial expiratory loop. Post-expiratory flow should be ≥ 6 seconds or 1 second plateau.
For a complete interpretation of spirometry, it is essential to evaluate static lung volumes such as total lung capacity (TLC), residual volume (RV), and functional residual capacity (FRC). Each of these volumes provides valuable insights into the health and efficiency of the respiratory system.
10 Σεπ 2024 · The European Respiratory Society and the American Thoracic Society have published guidelines for the measurement and interpretation of pulmonary function tests (PFTs) [2-10]. An overview of pulmonary function testing will be presented here, summarizing the types of PFTs and their indications.
15 Μαρ 2020 · High-quality, office-based spirometry provides diagnostic information as useful and reliable as testing performed in a pulmonary function laboratory.
