Validity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملComparison of tumor and normal tissue oxygen tension measurements using OxyLite or microelectrodes in rodents.
In this study we compare oxygen tension (PO2) histograms measured with O2 microelectrodes and a new optical PO2 measurement device, the OxyLite, in normal tissues (mouse spleen and thymus) and in tumors (R3230Ac in rats) (n = 5-6). The transient response to glucose infusion or 100% O2 breathing (hyperoxia) was also measured in tumors. PO2 histograms of spleen and thymus with the two devices wer...
متن کاملContinuous, transcutaneous oxygen tension measurements in experiments with rhesus monkeys and pregnant ewes.
After the first report by HUCH, HUCH, MEINZER and LÜBBERS on transcutaneous measurements of oxygen tension several papers describing this or similar electrodes based on the CLARK principle have been published [l, 3, 4, 12, 15, 18]. The technique has mainly been tested in perinatal medicine, but also in adults [7,8,13]. A publication on intrapartum registrations of human fetuses in considerable ...
متن کاملErrors in oxygen tension measurements caused by halothane.
Halothane, independent of oxygen tension, increased the signal of the gold/silver-silver chloride microelectrode. The output of microelectrodes at different oxygen tensions in the presence of increasing amounts of halothane has been measured. Halothane causes an increase in the electrode signal which is proportional to its concentration. This effect results from the polarographic reduction of h...
متن کاملOxygen tension measurements in bone marrow fleck cultures.
Cultures-Marrow fluid was aspirated from the sternum, ilium or vertebral spine and placed in a tube containing 1 mg. of heparin dissolved in 1 ml. of normal serum. After pouring it into a petri dish, the separated flecks of marrow w’re cultured as described dl’ Fifty marrow flecks from 7 individuals were cultured, and measurements of oxygen tension in the fluid medium were taken at intervals. C...
