Fig. 3From: Intracranial pressure responsiveness to positive end-expiratory pressure in different respiratory mechanics: a preliminary experimental study in pigsChanges of intracranial pressure with positive end-expiratory pressure increases. a Intracranial pressure (ICP) increased with positive end-expiratory pressure (PEEP) increases in all the conditions without intracranial hypertension (IH). b In the conditions without IH, the greatest cumulative change of ICP was observed in the CW condition, while the lowest one was observed in the L condition (both with statistical significance). c ICP decreased with PEEP increases in the conditions without IH. d No significant difference was observed in the change of ICP between the two conditions with IHBack to article page
