A major UK study shows that commonly used home pulse oximeters can overestimate oxygen levels in people with darker skin, increasing the risk of undetected hypoxemia and raising urgent questions about ...

Pulse oximeters that can be used at home to detect hypoxaemia give higher readings for patients with darker than lighter skin tones, according to UK researchers. As a result, they warn that low blood ...

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.

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 ...

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 EquiOx study showed that in critically ill patients, oxygen saturation assessed by pulse oximetry (SpO 2) was often lower than arterial oxygen saturation (SaO 2 ...

Discrepancies between pulse oximetry and arterial oxygen saturation can pose challenges in clinical assessment. Possible underlying causes include poor peripheral perfusion, skin pigmentation, motion ...

当我们谈及呼吸衰竭，其实更关注的是呼吸衰竭的病理生理机制以及基于此机制最终产生的结果。无论是通气功能障碍，还是换气功能障碍，都会导致氧气无法正常在体内运输，进而出现缺氧状态。通过氧输送（DO 2 ）公式【DO 2 =CaO 2 ×CO×10，CaO 2 =Hb×1.34×SaO 2 +PaO ...
