The authors discuss the importance of relationship between ICP and CPP which is subsequenxly formulaxed as indu The relationship between those two criteria seems to provide better characteristics of the situation in the cranium during the head-brain injury. The index allows for evaluation of the severity of dysfunction and for optimalization of intracranial hypertension therapy, in accordance with the results obtaireed from simultaneous monitoring of cerebral haemodynamics and tissue oxygenation as well as selected biochemical parameters.

        Key words: intracranial pressure - ICP - perfusion pressure - CPP - index ICP/CPP - regression analysis - inxracranial hypertension
