mbw cf4 Service for gas measurement

MBW assesses ventilation distribution inhomogeneity during tidal breathing from FRC, by examining inert gas clearance over a series of breaths. Exogenous gas washout requires an initial wash-in phase. MBW requires only passive cooperation and minimal coordination, but is more time consuming. It appears to be the most informative of these tests.
