BACKGROUND AND OBJECTIVE Multiple breath inert gas washout (MBW) systems are designed to minimize equipment dead space volume (Vd). Animal and infant studies have demonstrated the impact of increased Vd on MBW measurements. In this study, we investigate the effect of Vd of a nitrogen (N2 ) MBW system on MBW measurements in preschool children. METHODS N2 MBW measurements were performed in healthy adults under standard conditions; Vd was added to match the relationship between Vd and lung… CONTINUE READING
