A method of evaluating cerebrovascular reactivity comprising performing transcranial dopperografii at insonation segment Msrednih cerebral artery (MCA) with an estimate of the degree of increase in the average time of maximum blood flow velocity (TAMH) in AGR at hypercapnic load per unit of partial pressure of carbon dioxide in the alveolar air (PetCO), recorded capnography, characterized in that the maximum value recorded in the first 30 TAMH with hypercapnic load within PetCOne increase by more than 11 mmHg At which the systemic arterial blood pressure (BP) remains constant, the calculated index cerebrovascular reactivity to hypercapnia, independent of blood pressure (IRNAD), and its value in the range 1,1-3,2% at 1 mm Hg PetCOotsenivayut normal cerebrovascular reactivity.
