Nitric Oxide Lung Diffusing Capacity in Healthy, Non-smoking Adults

The measurement of nitric oxide lung diffusing capacity (DLNO) has been recently standardised. To date, two pulmonary function devices are commercially available and are used for the measurement of DLNO. No previous study assessed differences in gas exchange outcomes (e.g., DLNO values) between both devices. The aim of this project is to compare two commercially available devices that measure lung diffusing capacity for nitric oxide (DLNO). 1. "MasterScreenTM" (PFT Pro, Jaeger, CareFusion, Hoechberg, Germany 2. "HypAir" ("HA", Medisoft, Dinant, Belgium).
