[Measurement of total cerebral blood flow in man by means of the hydrogen clearance method].

The authors discuss a new method for measuring the overall cerebral blood flow in man from analysis of the hydrogen clearance curves recorded in the internal jugular vein with a sounding platinum electrode. The hydrogen clearance curves are polyexponential in character and for calculating the blood flow it is therefore necessary to use the stochastic method. The use of the "initial inclination" method is also admissible in proximate curve analysis. The values of the overall cerebral blood flow in patients with craniocerebral injury measured by the method suggested are in agreement with the data in the literature.
