The forced oscillation technique (FOT) allows easy assessment of bronchial reactivity. The use of a standard FOT generator (SG) results in changes in respiratory system resistance (delta Rrs,SG) which are affected by an artefact caused by the extrathoracic upper airway (EUA). The aim was to improve the FOT assessment of bronchial reactivity with the SG by computing the change in FOT admittance (delta Ars,SG), which is theoretically unaffected by this artefact. Delta Rrs,SG and delta Ars,SG… CONTINUE READING
