Figure 4

Experimentally determined expiratory time constants for the right chamber plotted against the compliance of the lung chambers. Both the right and left lung obstructions were held constant at kL = kR = 3.3. The test lung was ventilated with air or He/O2 with either a tidal volume of 500 ml at 12 breaths/min, producing minute ventilation of 6 l/min, or a tidal volume of 1000 ml at 20 breaths/min, producing minute ventilation of 20 l/min.
