A nitrogen washout can be performed with a single nitrogen breath, or multiple ones. Both tests use similar tools, both can estimate functional residual capacity and the degree of nonuniformity of gas distribution in the lungs, but the multiple-breath test more accurately measures absolute lung volumes.

WebDec 8, 2024 · There are several patterns of V/Q matching and mismatching: V/Q = 1.0: A lung unit with well-matched gas and blood flows will have a V/Q ratio close to 1.0, i.e. for every unit of blood flow it will receive a unit of gas flow. V/Q < 1.0: Good blood flow but insufficient ventilation; generally seen in the bases of lung (West's Zone 4) WebDec 1, 2004 · Methods:Forced expiratory volume in 1 second (FEV1) and maximal expiratory flow when 25% of forced vital capacity remains to be expired (MEF25) were compared with the lung clearance index (LCI) derived from sulphur hexafluoride MBW in 22 children with CF aged 6–16 years and in 33 healthy controls.
