- Fig. 1.
Flow-volume and post-occlusion tracheal pressure-volume curves during passive expiration in a representative patient. We divide the curves into 5 equal slices. The long arrow indicates the direction of expiration. The time constant and dynamic effective compliance of slice 1 is obtained by analyzing the flow-volume and pressure-volume relationships of the data from that slice.
- Fig. 2.
Relationship between albuterol-induced changes in the time constant of the total system (respiratory system, endotracheal tube, ventilator circuit, the change in the time constant, and the expiratory resistance of the respiratory system (ΔRRS) at each volume slice. The arrows indicate patients in whom the albuterol-induced change in the change in the time constant was in the opposite direction of ΔRRS.
