Nitrogen washout pulmonary function test
Webb7 nov. 2024 · There has been growing interest in studying small airway disease through measures of ventilation distribution, thanks to the resurgence of the nitrogen single-breath washout (N 2 SBW) test. Therefore, this study evaluated the contribution of the N 2 SBW test to the detection of pulmonary involvement in patients with rheumatoid arthritis (RA). WebbPulmonary function tests (PFTs) traditionally used in clinical practice do not accurately predict exercise intolerance in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to assess whether the nitrogen single-breath washout (N2SBW) test explains exercise intolerance and poor quality of life in stable COPD …
