Reactions of ICP, ITP, ABP, and CVP to an intrathecal bolus infusion in all sheep (A–F). Each spike is representative of a bolus infusion. Infusions contained 2 mL of Ringer’s solution, repeated six times per sheep. Please note that the timeframe represents elapsed time and that, in Sheep B and F, ICP and ITP are near equivalent. ICP, intracranial pressure; ITP, intrathecal pressure; ABP, arterial blood pressure; CVP, central venous pressure
