Abstract
In certain embodiments, a ventilator may provide interactive guidance for obtaining a subject's expiratory flow limitation results. In some embodiments, the ventilator may cause a progressive color component to be presented, where the progressive color component indicates a progression from one color proximate one side of the progressive color component to another color proximate another side of the progressive color component. The ventilator may cause a forced oscillation to be continuously applied to an airway of the subject for a time period. The ventilator may monitor the subject's degree of expiratory flow limitation based on output signals generated by one or more sensors as the forced oscillation is continuously applied for the time period. The ventilator may cause, based on the monitoring, a movable component's position on the progressive color component to be continuously updated during the time period to indicate the degree of expiratory flow limitation.
