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 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 کاملOxygen saturation in cystic fibrosis.
The availability of non-invasive oxygen saturation (SaO2) measurement could prove to be a useful tool for following up the progress of patients with cystic fibrosis. The present study was undertaken to compare its use with other routine measurements in the clinic. A total of 100 patients with cystic fibrosis were compared with 50 patients with stable asthma. The children were aged between 5 and...
متن کاملNormal jugular bulb oxygen saturation.
BACKGROUND Normal values of the jugular bulb oxygen saturation were obtained in 1942 and in 1963. Correct catheter positioning was not confirmed radiologically. OBJECTIVES To replicate the measurements during angiographic catheterisation of the jugular bulb. METHODS Oxygen saturation in the jugular bulb (SjO(2)), inferior petrosal sinus (SipsO(2)), and internal jugular vein was bilaterally ...
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...
