Pulse oximeter probes attached to the finger may fail to estimate blood oxygen saturation (SpO2) in patients with compromised peripheral perfusion (e.g. hypothermic cardiopulmonary bypass surgery). The measurement of SpO2 from a central organ such as the oesophagus is suggested as an alternative to overcome this problem. A reflectance oesophageal pulse oximeter probe and a processing system imp...

BACKGROUND Transport of mechanically ventilated patients in a combat zone presents challenges including conservation of resources. In the battlefield setting, the provision of adequate oxygen supplies remains a significant issue. Autonomous control of oxygen concentration may allow a reduction in mission load. METHODS Trauma patients requiring ventilation and inspired oxygen concentration (FI...

BACKGROUND Oxygen saturation has been shown in risk score models to predict mortality in emergency medicine. The aim of this study was to determine whether low oxygen saturation measured by a single-point measurement by pulse oximetry (SpO2) is associated with increased mortality in the general adult population. METHODS Pulse oximetry was performed in 5,152 participants in a cross-sectional s...

BACKGROUND Measures of oxygenation have not been assessed for prognostic significance in systemic sclerosis-related interstitial lung disease (SSc-ILD). METHODS 83 subjects with SSc-ILD performed a maximal cardiopulmonary exercise test with an arterial line. The agreement between peripheral oxygen saturation (SpO2) and arterial oxygen saturation (SaO2) was examined and survival differences be...

In recent years, oxygen targeting has become a relevant topic in neonatal intensive care medicine.1 Despite large SpO2 targeting trials including numerous subjects and the available results of a meta-analysis of these data,2,3 there is still an ongoing debate on the optimum SpO2 target range in preterm infants. Both conditions, hyperoxia as well as hypoxia, frequently occur in extremely low bir...

introduction: hypoxemia can occur during upper gastrointestinal endoscopy with or without pharmacological sedation. pulse oximetry saturation (spo2) levels were assessed in patients attending for routine unsedated diagnostic upper gastrointestinal endoscopy to identify factors associated with oxygen desaturation. methods: a total of 300 patients who underwent upper gastrointestinal endoscopy wi...

This study of paediatric intensive care patients aimed to determine where pulse oximetry probes shouid be placed to obtain the most accurate and reliable readings of peripheral oxygen saturation (SpO2). Using arterial blood gas analysis (SaO2) as the gold standard and SpO2 92% and SaO2 < 90% as indicators of hypoxaemia, negative predictive values of SpO2 were 96%, 98% and 98% at the ear, thumb ...

Splanchnic ischaemia can ultimately lead to cellular hypoxia and necrosis, and may well contribute to the development of multiple organ failures and increased mortality. Therefore, it is of utmost importance to monitor abdominal organ blood oxygen saturation (SpO2). Pulse oximetry has been widely accepted as a reliable method for monitoring oxygen saturation of arterial blood. Animal studies ha...
