Oxygen consumption of the living human brain measured after a single inhalation of positron emitting oxygen.
We measured the rate of washout of 15O-labeled water generated from labeled oxygen accumulated in brain after bolus [15O]O2 inhalation, and compared the washout with that of labeled water measured with H215O. Contrary to the original expectation, the radioactive water generated from labeled oxygen failed to leave the brain tissue at the rate predicted by exogenous water. Therefore, the use of a...
متن کاملA Computational Study of Oxygen Transport in the Body of Living Organism
Oxygen is an essential part of the living organism. It is transported from blood to the body tissue by the systematic circulation and large part of it is stored in the blood flowing in capillaries. In this work we discuss a mathematical model for oxygen transport in tissues. The governing equations are established assuming that the blood is flowing along a co-axial cylindrical capillary inside ...

متن کاملOxygen Consumption Rate of Tissue Measured by a Micropolarographic Method
A new method for measuring the oxygen consumption rate of a sheet of homogeneous tissue is described. The method measures, by a Clark-type oxygen electrode without a membrane, the time for the tissue to consume all its dissolved oxygen. The electrode is applied to one surface of the tissue sheet and the other surface is sealed from the atmosphere by a cover slip. The consumption is calculated f...
متن کاملEvaluation of adherence to oxygen therapy standards before, during and after oxygen hood administration
Background and Purpose: Oxygen therapy is one of the common treatments for neonates with cardiopulmonary disease. The aim of this study was to evaluate adherence to oxygen therapy standards by nurses before, during and after using oxygen hood. Methods: In this cross-sectional study, 250 cases of nursing care were evaluated before, during and after administration of oxygen hood therapy in pre...
