Changes in the relationship between VE and VCO2 during exercise in patients with pulmonary vascular disease
(A) On the left is the relationship of VE versus VCO2, and on the right the plot of VE/VCO2 versus time in a healthy individual. (B) Same plots seen in a patient with PAH, with increase in the slope of VE versus VCO2 and increase in the nadir of VE/VCO2 versus time.
