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

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, p...
