Pulse 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 کاملEffects of henna dye on oxygen saturation reading using pulse oximetry.
P oximetry is a non-invasive method that uses the spectrophotometric principle to monitor oxygen saturation in the blood. It produces a plethysmographic wave from which oxygen saturation is obtained.1 It is has become increasingly used in outpatient clinics and emergency rooms in addition to its use in critically ill patients and during anesthesia.1 Although it is an accurate method in reflecti...
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...
متن کاملPattern Analysis of Oxygen Saturation Variability in Healthy Individuals: Entropy of Pulse Oximetry Signals Carries Information about Mean Oxygen Saturation
Pulse oximetry is routinely used for monitoring patients' oxygen saturation levels with little regard to the variability of this physiological variable. There are few published studies on oxygen saturation variability (OSV), with none describing the variability and its pattern in a healthy adult population. The aim of this study was to characterize the pattern of OSV using several parameters; t...
متن کاملDiscrepancies between arterial oxygen saturation and functional oxygen saturation measured with pulse oximetry in very preterm infants.
BACKGROUND Discrepancies between pulse oximetry saturation (SpO(2)) and arterial saturation (SaO(2)) at low blood oxygenation values have been previously reported with significant variations among instruments and studies. Whether pulse oximeters that attenuate motion artifact are less prone to such discrepancies is not well known. OBJECTIVE To prospectively assess the agreement of the Masimo ...
