Percent change in pial arteriolar diameter (means ± SE) during hypocapnia at the beginning of the protocol before l-NNA superfusion or exchange transfusion (pre-) and after intervention (post-) with either superfu-sion of l-NNA and no transfusion (l-NNA/Control; n = 9 cats), with superfusion of l-NNA and subsequent exchange transfusion of Alb solution (l-NNA/Alb; n = 6 cats), with superfusion of artificial CSF and subsequent exchange transfusion of cross-linked Hb solution (CSF/Hb; n = 8 cats), and with superfusion of l-NNA and subsequent exchange transfusion of cross-linked Hb solution (l-NNA/Hb; n = 7 cats). Responses were segregated by vessels with initial diameters of <50 μm, 50–100 μm, and >100 μm. *P < 0.05 from corresponding pretransfusion response by paired t-test.
