Meta-analysis of arterial oxygen saturation monitoring by pulse oximetry in adults
OBJECTIVE: The purposes of the study were to: (1) describe the aggregate strength of the relationship of arterial oxygen saturat ion as measured by pulse oximetry with the standard of arterial blood gas analysis as measured by co-oximetry, (2) examine how various factors affect this relationship, and (3) describe an aggregate estimate of the bias and precision be tween oxygen saturation as meas...

متن کاملPulse Oximetry Overestimates Oxygen Saturation in COPD.
BACKGROUND Measurement of oxygen saturation with a handheld pulse oximeter is widely practiced as a surrogate to invasive arterial blood gas analysis. Oxygen saturation is an important parameter in cases of COPD, but there are insufficient data on the role of pulse oximetry in patients with COPD, moreso in diseases across its spectrum, such as chronic bronchitis and emphysema. We assessed the p...
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 کاملevaluation of oxygen saturation by pulse-oximetry in mouth breathing patients
mouth breathing might not always result in hypoxia, but can contribute to it. the aim of the present study was to determine the effect of mouth breathing on hypoxia. based on a pilot study, 323 patients with mouth breathing were selected. assessment of mouth breathing was based on clinical examination and questionnaires filled out by patients and their companions. the patients were also examine...
