I'm trying to figure out the cardiac and vascular function curves on pg. 252 of the 2010 First Aid and one of the changes it has says "increased TPR, e.g., exercise." Then it has the vascular function curve moved to the right (not rotated) indicating an increase in mean systemic pressure. Is that correct? BRS phys. says an increase in TPR will just rotate the vascular function curve counterclockwise, with no change in mean systemic pressure, but I guess exercise might cause venoconstriction that would account for the change. Idk, I'm confused, anybody know the answer??
