In the EXAKT study from the U.K., the home-use pulse oximeters assessed all gave higher oxygen saturation (SpO2) readings for patients with darker skin tones than for patients with lighter skin tones.

Abstract: This paper proposes a novel mathematical model that quantitatively defines the relationships between the arterial oxygen saturation (SaO2), the arterial partial pressure of oxygen (PaO2) and ...

The SOFA-2 score included new definitions, new variables, and revised thresholds to categorize the severity of organ dysfunction in critical illness. The updates reflected changes in practice, ...

Serious hidden hypoxemia — defined as an SaO2 less than 88% despite an SpO2 of 92% or greater — occurred in 0.6% of the critically ill Asian patients studied. Hypoxemia went undetected in 0.8% of ...

Patients with COPD who travel to high altitudes have an estimated PaO2 decrease of 0.84 kPa with each 1000 meter of altitude gain. High-altitude travel in patients with chronic obstructive pulmonary ...

Credit: Masimo. The pulse oximeter is intended for spot-checking of functional oxygen saturation of arterial hemoglobin and pulse rate. The Food and Drug Administration (FDA) has cleared Masimo ...

Chronic obstructive pulmonary disease (COPD) is globally the third leading cause of death, causing 3.23 million deaths in 2019. Most feasible way to measure oxygen saturation is by pulse oximetry ...

The objective is to compare supine and prone positions in terms of arterial blood gas during lithotripsy endourology procedures in different stages. Cases of during lithotripsy endourology procedures ...

PaO2 is the partial pressure of oxygen in the blood that represents the overall oxygen content. It is different from SaO2 and SpO2 in that it measures how much oxygen is present, rather than the ...
