[Estimation of individual levels of the physiological expenditures during mental work].

A new approach for determination of the individual levels of physiological expenditures in mental work is proposed. Comparison of adaptation reaction amplitude of cerebral arteries with the homeostatic range scale of cerebrovascular reactivity in human-operator gives the possibility to determine individual levels of the physiological expenditures in mental work. The homeostatic range of cerebrovascular reactivity was determined by hyper- and hypocapnia functional test. Using transcranial doppler the mean blood flow velocity in the middle cerebral artery was measured. Estimation of the individuals levels of physiological expenditures in mental work allows determination of the potential possibility of the individual person to perform this type of work.
