Abstract

Background: The Innocor device contains a highly sensitive photoacoustic gas analyzer that was used to perform multiple breath washout (MBW) measurements using very low concns. of the tracer gas SF6. Use in smaller subjects was restricted by the requirement for a gas analyzer response time of
