Figure 4.

Effect of albuterol on pulmonary capillary blood volume and gas diffusion at the individual alveolar-capillary unit (D_M/V_C) in healthy and CF subjects. Panel A: Pulmonary capillary blood volume (V_C). Panel B: Gas Diffusion at the Individual Alveolar-capillary Unit (D_M/V_C). The open circles represent subjects with CF with the response overtime shown as the broken line. The closed diamonds represent healthy subjects with the response overtime shown as the solid line. The error bars represent the standard error of the mean.

Notes:^†baseline vs. time post in CF subjects.
