Complete Pulmonary Function Testing
- Spirometry: Pre & Post Bronchodilator, flow volume loop
- Lung Volumes: measured by inert gas dilution or nitrogen washout can clarify whether a restrictive or obstructive process is the cause of a decreased Forced Vital Capacity (FVC) and Forced Expiratory Volume in the 1st second (FEV1).
- Diffusing Capacity (DLCO): Following ATS PFT algorithm, DLCO is useful in delineating PV: pulmonary vascular; CW: chest wall; NM: neuromuscular; ILD: interstitial lung diseases; CB: chronic bronchitis once Spirometry and Lung Volumes have been considered.
