Inert gas diffusion method for measurement of blood flow using saturation techniques. Comparison with directly measured blood flow in isolated gastrocnemius muscle of the cat.
The isolated gastrocnemius muscle of the cat was used to study the relation between the desaturation of xenon measured by external monitoring, and blood flow measured directly by a dropcounter. The metered blood flow agreed with that calculated from the initial slope of the desaturation curve from tissue equilibrated by prolonged intra-arteria] infusion and also by atraumatic gas labelling of a...
متن کاملInert gas diffusion method for measurement of blood flow. Comparision of bolus injection to directly measured blood flow in the isolated gastrocnemius muscle.
The isolated cat gastrocnemius preparation was used to study the relation between the washout of Xenon measured by external monitoring and blood flow measured directly by a dropcounter. The experimental possibility was thereby tested of recording the total tracer bolus and its subsequent washout by external monitoring, using the height H and the corresponding area A of the washout curve. The pa...
متن کاملA method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow
Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...
متن کاملNewer techniques of cerebral blood flow measurement.
• A variety of methods for measuring cerebral blood flow have been developed in the past 25 years since Kety and Schmidt developed their method based on the Fick principle. None of the currently used methods approaches the clinical ideal, since none of the techniques are accurate, reproducible and noninvasive. Most accurate techniques involve catheterization of internal carotid artery and/or ju...
متن کاملCerebral Blood Flow Determined by Saturation and Desaturation with Krypton-85: an Evaluation of the Validity of the Inert Gas; Method of Kety and Schmidt.
• In the original inert gas method of Kety and Schmidt the saturation of the brain with the inert gas, N,,O, is followed for 10 minutes. In a group of subjects we have studied both the saturation and the desaturation of the brain with krypton as the inert gas. The results give an experimental demonstration of a relatively small systematic error inherent in the method apparently due to differenc...
