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.

A total of 11,018 paired SpO2-SaO2 measurements were analysed. All five pulse oximeters returned higher SpO2 values for patients with darker skin tones than patients with lighter skin tones, at any ...

NASHVILLE, Tenn. -- Racial biases persist in the use of pulse oximetry devices for patients with acute hypoxemic respiratory failure (AHRF) requiring very high levels of oxygen support, a ...

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 ...

What Is an Arterial Blood Gas Test (ABG)? An arterial blood gas (ABG) test measures oxygen and carbon dioxide levels in your blood. It also measures your body’s acid-base (pH) level, which is usually ...

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 ...
