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 ...

Oxygen is the second most abundant element in Earth's atmosphere. Although critical for aerobic respiration, it also poses significant dangers to life. The reduction of molecular oxygen to water by ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the ...

Objectives To assess the impact of skin tone on the measurement and diagnostic accuracy of five fingertip pulse oximeters used by patients in the NHS (National Health Service) England COVID Oximetry ...

Persistent pulmonary hypertension of the newborn (PPHN) is the most common neonatal form and mostly reversible after a few days with improvement of the underlying pulmonary condition. When pulmonary ...

This is an important study that utilized in vivo optical measurements of the cortical metabolic rate of O2 and blood flow, as well as measurements in isolated mitochondria to assess the uncoupling of ...

BACKGROUND Acute changes in hemodynamics and oxygen delivery accompanying temporary occlusion of atrial defects in 14 patients after a fenestrated Fontan procedure were evaluated at a median interval ...
