Intracranial pressure (ICP) and cerebral perfusion pressure (CPP) during a five-and-a-half-hour time period. Intracranial hypertension was noted at 11:40 a.m., one hour after the start of hemodialysis (HD). Intracranial hypertension at 12:30 p.m. was due to hypotension after increased neurosedation and at 1:30 p.m. was due to hypercapnia (50 mm Hg) after a change of ventilation mode (from assisted spontaneous breathing to synchronized controlled mechanical ventilation).
