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 ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...

Abstract: In this work, a detection and classification method for sleep apnea and hypopnea, using photopletysmography (PPG) and peripheral oxygen saturation (SpO 2) signals, is proposed. The detector ...

An ABG test checks how well your lungs and kidneys work by measuring oxygen and carbon dioxide in your blood. This test helps doctors know if your body has an acid-base balance issue and if treatment ...

To take a pulse oximetry reading, turn on the device, place it on your fingertip, sit still, and wait for a stable reading. Normal oxygen saturation levels range from 95% to 100%; levels below 92% may ...

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 ...

Conclusions: SpO2 and PR measurements may be inaccurate across all skin pigmentation groups, breaching U.S. Food and Drug Administration guidance and industry standard thresholds. Pulse oximeters ...
