  • Abstract
  • Look Inside

The effects of acidosis on ischemic brain damage are unclear and probably diverse. To establish an in vivo model of acidosis, the authors assess changes in extracellular brain pH (pHe) , CBF and ICP induced by hypercarbic ventilation, and discuss the reliabi-lity and short comings of this experimental model. Acidosis was induced by increasing the inspired CO2 concentration in mechanically ventilated rats. pHe was measured with a pH-sensitive electrode im-planted into the cortical mantle.
