Figure 2

Determination of expiratory time constant. Example of determining the expiratory time constant (ƬE) for one patient in the study is shown. ƬE was determined by point-by-point analyses of exhaled tidal volume (VT) and flow rate values between 0.10 and 0.50 seconds, that is, the exhaled VT and flow rate curves are substituted by a fitted straight line (least squares fit) and the slope of the line is ƬE.
