Oxygen saturation versus oxygen tension

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...

Mind the influence of arterial oxygen tension on central venous oxygen saturation

We read with great interest the study by Hernandez and colleagues published in Critical Care [1]. The study showed that central venous oxygen saturation (ScvO2) increased significantly in response to emergency intubation, and the authors suggested that the early normalization of ScvO2 after intubation might not be reliable to reflect successful resuscitation. However, they might have ignored th...

pulse 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...

Correlation between Pulse Oximetry Oxygen Saturation (SpO2) and Measured Arterial Oxygen Saturation (SaO 2 ) and Arterial Oxygen Tension (PaOz) in Neonates

=Abstract=Pulse oximetry has recently been introduced as a method for continuous and non-invasive transcutaneous monitoring of arterial oxygen saturation in neonates. The purpose of our study was to determine the reliability, accuracy, and practicability of pulse oximetry for monitoring arterial oxygenation in sick newborn infants. Pulse oximetry oxygen saturation values (SpO2) were compared wi...
