background & aim : pulse oximetry is a frequently used and standard non-invasive method for monitoring oxygen (o2)-saturation in blood. many factors including dark skin and pigmentation may effect on rate of saturation of the blood oxygen absorbed by pulse oximetry. the effect of nail polish and/or henna color on blood oxygen has not been yet identified and the present study has been carried ou...

BACKGROUND Transition from a parallel circulation in utero to an in-series circulation immediately after birth is partly an oxygen-dependent process. Relative hypoxemia with increasing altitude above sea level exerts a certain degree of stress on oxygen-dependent metabolic processes throughout the body. OBJECTIVE The present study aimed to determine the reference values for oxygen saturation ...

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...

RATIONALE At-home nocturnal pulse oximetry has a high positive predictive value (PPV) for polysomnographically-diagnosed obstructive sleep apnea (OSA) but no studies have been published testing the night-to-night consistency of at-home nocturnal pulse oximetry for the evaluation of suspected OSA in children. We therefore determined the night-to-night consistency of nocturnal pulse oximetry as a...
