Due to the principles of Hb oxygen dissociation curve, peripheral oxygen saturation has an approximate sensitivity and specificity of 90% for the detection of hypoxemia [4]. Oxygen Reserve Index (ORiⓇ) (Masimo Corp., Irvine, CA, USA) is a novel continuous and noninvasive parameter that ...
Interventions: Participants were randomly assigned to hyperoxia (1.00 fraction of inspired oxygen [FiO2]) or normoxia (minimum FiO2 to maintain oxygen saturation 95%-97%) throughout surgery. Main Outcomes and Measures: Participants were assessed for oxidative stress by measuring...
Introduction Since its invention in 1974, near-infrared pulse oximetry (SpO2) has allowed for convenient, noninvasive transcutaneous monitoring of arterial hemoglobin oxygen saturation.1,2 This technology uses spectrophotometry to indirectly calculate the arterial hemoglobin saturation by determining the propor...
, differences in the saturation value of dissolved oxygen, and the effects of temperature, respectively. The alpha factor (a) is used to compare the oxygen transfer effectiveness in a given wastewater to its effectiveness in clean water: (7-51)α=KLaww/KLacw where KLaww = The value of ...
Meaning In this study, discrepancies in pulse oximetry accuracy among racial and ethnic subgroups were associated with higher rates of hidden hypoxemia, mortality, and organ dysfunction. Abstract Importance Discrepancies in oxygen saturation measured by pulse oximetry (Spo2), when compared with arterial ...

A single radiation-induced superoxide ion $$O_{2}^{ - }$$ has been observed for the first time in metal oxides. This structural defect has been revealed in fast-neutron-irradiated (6.9×1018 n/cm2) corundum (α-Al2O3) single crystals using the EPR method

The majority of hospitals had an oxygen saturation as measured by pulse oximetry (Spo2) threshold set at 92% or greater; 1 hospital had a lower Spo2 threshold set at 90% or greater. Diagnoses leading to acute hypoxemic respiratory failure included pneumonia, pneumonitis, acute lower respiratory ...
The research also showed that all of the people who vaped – with or without nicotine - had decreased oxygen saturation, meaning their lungs were probably taking in less oxygen. Nabbout said the goal of the study is to help regulators as they make decisions about which of these products shoul...
