Impact of Skin Pigmentation on Pulse Oximetry Blood Oxygenation and Wearable Pulse Rate Accuracy: Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Photoplethysmography (PPG) is a technology routinely used in clinical practice to assess blood oxygenation (SpO₂) and pulse rate (PR). Skin pigmentation may influence accuracy, leading to health outcomes disparities.

Objective

This systematic review and meta-analysis primarily aimed to evaluate the accuracy of PPG-derived SpO₂ and PR by skin pigmentation. Secondarily, we aimed to evaluate statistical biases and the clinical relevance of PPG-derived SpO₂ and PR according to skin pigmentation.

Methods

We identified 23 pulse oximetry studies (n=59,684; 197,353 paired SpO₂-arterial blood observations) and 4 wearable PR studies (n=176; 140,771 paired PPG-electrocardiography observations). We evaluated accuracy accordin
