説明

We recorded the change of blood flow velocity before, during and after hyperventilation (HV) in bilateral Internal Carotid Arteries (ICA) and Vertebral Arteries (VA) simultaneously and continuously of 4 healthy males.<BR>The MULTI-DOPPLER-SYSTEM (HAYASHI ELECTRIC, Inc. Kawasaki, JAPAN) and four ultrasonic probes fixed by a cervical brace (KAWAMURA ARTIFICIAL LIMB, Inc.Osaka, JAPAN) were used to obtain data.<BR>We calculated Averaged Maximum Velocity (AMV) for every heart beat as the Index of blood flow and visualized them in 4 subjects.<BR>AMV repeatedly increased and decreased every several seconds. HV induced a statistically significant AMY decrease. The AMY interrelations between any two vessels in each subject were all statistically significant. The coefficients of correlation were largest during HV and smallest before HV.
