| Popis: | Regional cerebral blood flow in the cat was quantitatively measured by Xe133 clearance and mass spectrographic monitoring of argon washout. No statistical difference was observed in the values obtained for regional cerebral blood flow by the two methods. Although the mass spectrometer cannula caused some brain damage, since brain PO2 and pCO2 were monitored simultaneously, significant tissue trauma was detected early. The mass spectrographic technique enables precise measurement of blood flow in any locality, and tissue PO2 and pCO2 can be simultaneously recorded. |
