From Germany to Brittoneel. at the University of Gottingen devised the first platinum oxygen electrode. However, I did work in Gottingen (1962-1963) with Kurt Kramer. My acquaintanceship with Kramer began in 1946 while I was a medical student. James Elam, an investigator at Washington University, and I, with advice from E

Oxygen Electrodes and Optodes and their Application ,ients develop, the state of tissue oxygen supply can be characterized by the distribution of local pO.. At that time, however, it was only possible to measure mean tissue pO.. This was done by introducing e.g. a small gas bubble into the tissue.. After equilibration the bubble was withdrawn and anal

Cerebral Oxygenation During Cardiopulmonary Bypassery(l,2). The introduction of alpha stat C0. regulation for hypothermic cardiopulmonary bypass (CPB) preserves auto regulation of cerebral blood flow if mean arterial blood is maintained above 50 mm Hg(3), and it was thought that cerebral perfusion was likely to be adequate for the reduced cerebral

Measurement of Oxygen Pressure Using 19F-NMR Imagingfect that the longitudinal relaxation rate (R. = 1/T.) increases linearly with the partial oxygen pressure (pO.) when the temperature is kept constant [1,2]:. The calibration constants A and B depend strongly on temperature, magnetic field strength, the fluorinated subtances, the resonance line used

The optode has the inherent advantage towards the established method of electrochemical oxygen measurements that the sensor is permeable for oxygen and does not consume the analyte. With this new sensing principle (Fig

Comparison Between Conventional Hemodynamic Monitoring and Polarographic Tissue PO2-Monitoring of thwithin physiological limits. A frequently employed therapeutic option is catecholamine administration. Since the reduction of peripheral vascular resistance in septicemia is at least partly due to a TNF induced vascular NO-synthase, the inhibition of this system does affect tissue perfusion as well.

Estimation of Cerebral Blood Volume and Transit Time in Neonates From Quick Oxygen Increases Measureometry (NIRS) (Edwards et al, Skov et al., Bucher et al.). One of the essential assumptions for the correct estimation of cbf by the Fick principle is, that the time a bolus of tracer needs to pass the cerebral compartment - the so-called transit time (tt) - exceeds 6s to 8s. This paper describes a
