▪ Abstract Interrogation of tissue with light offers the potential for noninvasive chemical
measurement, and penetration with near-infrared wavelengths (750–1000 nm) is greater …

Near-infrared spectroscopy (NIRS) is a noninvasive optical technique that allows evaluation
of oxygen availability and oxygen consumption relationships within a living tissue. It can be …

Metabolic products of skeletal muscle contraction activate metaboreceptor muscle afferents
that reflexively increase sympathetic nerve activity (SNA) targeted to both resting and …

The aim of this paper is to review techniques that are currently available to measure tissue
hypoxia in order to benefit the management of wounds. Direct measurement of tissue partial …

The relationships among mitochondrial O2 availability, O2 delivery, and lactate formation in
exercising skeletal muscle remain unclear. Some data suggest that muscle O2 provision is …

Conflicting patterns of change in cytochrome c oxidase (Cyt a, a 3) redox status have been
obtained between different near-infrared spectrophotometers when making measurements …

Myocardial oxygenation may be altered markedly by changes in tissue blood flow. During
brief ischemia and reperfusion produced by transient occlusion of the left anterior …

Regional myocardial oxygenation was assessed during partial and complete coronary artery
occlusion using near infrared spectroscopy. In eight open-chest dogs, partial occlusions …

Although near-infrared (NIR) spectroscopy may one day provide a noninvasive
measurement of oxidative metabolism in tissue, the method cannot be fully quantitative until …

Objective Near-infrared spectroscopy (NIRS) is a noninvasive technique with the potential to
determine the degree of tissue oxygenation. The aim of the current study was to investigate …
