Проанализированы данные спектрометрических измерений плотности, площади сечения микроциркуляторных сосудов поверхностных тканей, содержания в крови тканевых сосудов оксигемоглобина и их реакции на прекращение кровотока, ограничение притока артериальной крови и блокады оттока венозной крови. Характер и направленность полученных изменений согласуются с существующими представлениями о физиологических и патофизиологических механизмах реагирования сосудов и метаболизма тканей на нарушения локального кровотока. Метод спектрометрии может найти применение для оценки соответствия микроциркуляции метаболическим потребностям тканей в условиях физиологических нагрузок и патологии.
ключевые слова: спектрометрия, микроциркуляция, оксигемоглобин, потребление кислорода, метаболизм тканей

Physiological evaluation of spectrometry results of oxyhemoglobin content and response of microvessels to hemodynamic changes
A.I. Kubarko, V.A. Firago
Spectroscopic measurements of the density and cross-sectional area of microcirculation vessels of superficial tissues, oxyhemoglobin blood content in these vessels and their response to the blood flow cessation, restriction of arterial blood flow and blockade of venous outflow have been analyzed. The character and direction of the revealed changes are consistent with the existing concepts of the physiological and pathophysiological mechanisms of vascular and tissue metabolism response to the local blood flow disorders. The spectrometry method can be used to assess the compliance of microcirculation to the tissues metabolic needs in functional stress and pathology.
keywords: spectrometry, microcirculation, oxyhemoglobin, oxygen consumption, tissue metabolism
