Abstract

The forced oscillation technique (FOT) is a non-invasive method to assess airway functionby emitting oscillatory signals into the respiratory tract during tidal ventilation. This opinionpiece discusses the current use, trialled modification and future directions in utilizing FOT asa novel diagnostic tool for early detection of small airway changes in smokers. The publishedevidence to date has shown that FOT parameters could be a sensitive diagnostic tool to detect earlyrespiratory changes in smokers. Multiple frequencies and the frequency dependence of resistance andreactance can provide the most valuable and early information regarding smoking induced changesin airways. Considering its non-invasiveness, lower level of discomfort to patients than spirometry,feasibility, and cost effectiveness, it could be the first-choice diagnostic technique for detection of earlyrespiratory changes in smokers. The finding of FOT could further be supported and correlated withinflammatory markers.
