Fig. 4From: Intracranial pressure responsiveness to positive end-expiratory pressure in different respiratory mechanics: a preliminary experimental study in pigsChange of hemodynamic parameters with positive end-expiratory pressure increases. a Central venous pressure (CVP) increased with positive end-expiratory pressure (PEEP) increases in all the conditions. CVP was significantly higher in the conditions with chest wall and abdomen strapping. b The change of CVP was significantly lower in the conditions with only lung injury (L and L + IH conditions). c Mean arterial pressure (MAP) decreased with PEEP increases in all the conditions. d The change of MAP was significantly greater in the conditions with intracranial hypertension (IH). e Cerebral perfusion pressure (CPP) decreased with PEEP increases in all the conditions. CPP was significantly lower in the conditions with IH. f No significant difference was observed in the change of CPP between the conditionsBack to article page
