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 کاملSpectrophotometric determination of the oxygen saturation of whole blood.
A new approach to the spectrophotometric determination of blood oxygen saturation has been made which is based on the absorption maximum of oxyhemoglobin and the isosbestic point of oxyhemoglobin and hemoglobin. The precision of this new method is comparable to that of the manometric procedure in which the Van Slyke-Neil1 apparatus is employed; there is also good correlation between results obt...
متن کاملpulse oximeter oxygen saturation in prediction of arterial oxygen saturation in liver transplant candidates
results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...
متن کاملManometric Determination of Hemoglobin by the Oxygen Capacity Method
Since Van Slyke (1) originally described a gasometric method for the determination of hemogIobin by analysis of the oxygen-combining power of blood, it has been the practice to saturate the blood with air at atmospheric pressure in a separate vessel and to transfer a sample of the aerated blood to the gas analyzing apparatus. A method is described here which requires less time, material, and ap...
متن کاملThe spectrophotometric determination of the oxygen saturation of blood.
ORDY AND DRABKIN (1) have described a simplified spectrophotometric procedure for the determination of oxygen saturation of whole hemolyzed blood. The described method of sampling by use of tonometers, although technically precise, is somewhat inconvenient for routine clinical use. In a note appended to the article, Marsh described a simpler modification. He collects the samples in oiled, hepar...
