- Cerebral blood flow during orthostasis: role of arterial CO2J M Serrador
Division on Aging, Harvard Medical School, Beth Israel Deaconess Medical Center, One Deaconess Rd, Palmer 117, Boston, MA 02215, USA
Am J Physiol Regul Integr Comp Physiol 290:R1087-93. 2006..Furthermore, the reduction in Pa(CO(2)) did not fully explain the decrease in CFV throughout HUT. These data suggest that factors in addition to a reduction in Pa(CO(2)) play a role in the CBF response to orthostatic stress...
- Loss of otolith function with age is associated with increased postural sway measuresJorge M Serrador
