Note d'application: Técnica no invasiva que utiliza las propiedades de absorción diferencial de la hemoglobina y mioglobina para evaluar la oxigenación tisular y que indirectamente puede medir la hemodinámica regional y el flujo sanguíneo. La luz cercana al infrarrojo (NIR) se propaga a través de los tejidos y se absorbe de modo diferencial en longitudes de ondas determinadas por las formas oxigenadas frente a las no oxigenadas de la hemoglobina y la mioglobina. La iluminación de tejidos intactos con luz infrarroja cercana permite la evaluación cualitativa de cambios en la concentración tisular de esas moléculas. El análisis se usa también para determinar la composición corporal.

Note d'application: A noninvasive technique that uses the differential absorption properties of hemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional hemodynamics and blood flow. Near-infrared light (NIR) can propagate through tissues and at particular wavelengths is differentially absorbed by oxygenated vs. deoxygenated forms of hemoglobin and myoglobin. Illumination of intact tissue with NIR allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.
