Cerebral autoregulation and the CO2 reactivity
Primary physiology — the CPP = MAP - ICP; the autoregulation (the constant CBF over the MAP 60-150 mmHg); the right shift in the chronic hypertension; the loss in the brain injury; the CO2 reactivity (the 3 per cent CBF change per mmHg PaCO2); and the agent effects.
