(a) Relative change of the heart rate during the neuroendoscopic procedures plotted against the lowest preceding cerebral perfusion pressure. (b) Relative change of the mean arterial pressure during the neuroendoscopic procedures plotted against the lowest preceding cerebral perfusion pressure. The events from patient 14 are shown by open squares; many of these haemodynamic events occurred during tumour retraction.

(a) Relative change of the heart rate during the neuroendoscopic procedures plotted against the lowest preceding intracranial pressure. (b) Relative change of the mean arterial pressure during the neuroendoscopic procedures plotted against the lowest preceding intracranial pressure. The events from patient 14 are shown by open squares; many of these haemodynamic events occurred during tumour retraction.

4. Fig 3
(a) After stable adaptive hypertension due to moderately increased intracranial pressure (ICP), a sudden increase in ICP results in a manifest Cushing reflex, which tends to normalize after ICP is lowered. (b) Occurrence of an acute bradycardia and hypertension following a drop in the cerebral perfusion pressure (CPP) to <30 mm Hg. (c) Occurrence of a Cushing reflex in a 3-month-old baby.
