Fig. 8From: Intercompartmental communication between the cerebrospinal and adjacent spaces during intrathecal infusions in an acute ovine in-vivo modelReactions ICP, ITP, ABP, and CVP to intrathecal constant pressure infusions in all sheep (AâF). Constant pressure infusions were completed by setting a baseline for each sheep and increasing and maintaining the ITP at 3.75Â mmHg above the previous step for 7Â min. Constant pressure infusions were unable to be completed in sheep A due to hardware limitations. Please note that the timeframe represents elapsed time. ABP, arterial blood pressure; ICP, intracranial pressure; ITP, intrathecal pressure; CVP, central venous pressureBack to article page
