  • Abstract
  • Look Inside

Using skull impedance plethysmography, a deve-lopmental approach was made to the measurement of mean cerebral blood flow (mCBF) from brain volume exchanging ratio (ΔV) involved in bilateral jugular venous occlusion. An experimental study thereof revealed the following results:

Comparative examinations were made between total cerebral blood flow obtained by the superior sagittal sinus hydrogen clearance method and ΔV・t obtained by the present approach led to the establishment of a linear correlation therebetween and also of the following calculating formula: mCBF=k×ΔV・t (Ω・sec) k: proportional coefficient
