Measurement of local cerebral blood flow in the unanesthetized rat using a hydrogen clearance method.
The hydrogen clearance method for measuring local tissue blood flow was adapted for use in the brain of the unanesthetized rat by means of a stainless steel plate screw mounted in the skull as the reference electrode instead of a calomel electrode. Blood flow was measured at 3 sites in the brains of 5 threemonth-old rats over a 6-week period. Blood flow in the frontal cortex and the cerebellum ...
متن کاملMeasurement of Local Blood Flow with Hydrogen Gas.
• The use of inert gases was introduced for measuring cerebral blood flow by Kety and Schmidt in 1945* and has since found wide application to the brain and other regions. Nitrous oxide has been used for measuring cerebral, myocardial, and renal blood flow," while labelled krypton has been used for the same organs by other investigators." The method requires simultaneous measurement of the gas ...
متن کاملUsefulness of intraoperative cortical blood flow measurement by heat clearance method for monitoring cerebral ischaemia during therapeutic carotid ligation.
Changes of regional cortical blood flow (rCBF) was monitored by the heat clearance method during the operation of cervical carotid ligation combined with superficial temporal artery and middle cerebral artery anastomosis for the treatment of inaccessible aneurysms of the internal carotid artery in eight patients. There were three types of rCBF responses upon closure of the internal carotid arte...
متن کاملContinuous quantitative local cerebral blood flow measurement. Calibration of thermal conductivity measurements by the hydrogen clearance method.
The capability of a miniaturized probe to measure local cerebral blood flow in a continuous and quantitative manner is described. The incorporation of thermal conductivity measurements using the isothermal principle with the hydrogen clearance method allows calibration of the thermal conductivity component in absolute terms. Evaluation of this system in 14 cats showed a linear relationship betw...
متن کاملMeasurement of myocardial blood flow.
This paper represents a review of the recent literature on techniques to measure myocardial blood flow in man. A short discussion on flow meters in followed by a more detailed discussion of the radionuclide techniques used to measure myocardial blood flow. The radionuclide techniques are discussed in two groups: (1) qualitative measurement of blood flow using static images; and (2) quantitative...
