Algorithm for calculating regional time constant τ reg. Of note, curve fitting starts at the time when 75% of peak signal is reached (see “Methods”). V(t): volume at time point t, V0 volume at start of expiration, t the time from the start at end-inspiration to the end of expiration, τ the expiratory time constant and C the end expiratory volume
