Figure 9From: Bench and mathematical modeling of the effects of breathing a helium/oxygen mixture on expiratory time constants in the presence of heterogeneous airway obstructions Flow versus time data measured experimentally (black lines), and predicted analytically (gray lines) for the right lung compartment under several test conditions: a) air and b) He/O 2 with C R ā=ā0.05āl/cm H 2 O, k R ā=ā3.3, and Veā=ā6āl/min; and c) air and d) He/O 2 with C R ā=ā0.05āl/cm H 2 O, k R ā=ā132.9, and Veā=ā20āl/min.
