Question
The below graph shows changes in several cardiovascular parameters as the result of increased intensity of exercise in a population of untrained individuals. What commonly measured cardiovascular parameters might the curves labeled A, B, and C represent? What are the corresponding units for the y-axis of each measure? For your reference, the two labeled curves represent the Pulmonary Capillary Wedge Pressure (PCWP) and the Central Venous Pressure (CVP), both of which are measured in mmHg.
