Comparative assessment of healthy tissue oxygenation using near-infrared imaging, transcutaneous oxygen measurement, and plethysmography.

ABSTRACT: The COVID-19 pandemic highlighted critical limitations in conventional pulse oximetry, especially in diverse populations. This study evaluates the performance of noninvasive devices for assessing tissue oxygenation in a cohort of 20 healthy individuals, with a focus on device sensitivity, physiological and demographic variables. Tissue oxygenation was measured using devices: spatial frequency domain imaging (SFDI), transcutaneous oxygen measurement (TCOM), wearable photoplethysmography (WD), and pulse oximetry (PO) during baseline, ischemia, and reperfusion phases. Comparative analyses were performed across devices, sex and Fitzpatrick skin types. Among the four devices, SFDI uniquely detected significant differences in tissue oxygen saturation (StO₂), highlighting its sensitivi
