Diagnostic significance of simultaneous pulsooximetry and thermometry for respiratory pathology in young children

Abstract

The state of the microcirculatory bed plays a decisive role in the metabolic processes of organs and tissues. The intensity and direction of metabolic processes in tissue cells depend on the mass transfer of oxygen by blood. At present, it is well known that in a number of severe infectious diseases, there is a significant violation of the microcirculatory transport properties of oxygen and oxygen utilization by tissues. Various indirect methods have been proposed to help objectively assess the state of the vascular bed. For the non-invasive assessment and detection of these metabolic and microcirculatory changes, current clinical protocols advise measuring saturation - tissue oxygen saturation (StO2) using pulse oximetry. Purpose of the study. To study the variability and clinical significance of the combined one-time indicators of saturation (StO2) and local t0 for different measurement zones in children with respiratory pathology. To achieve this goal, in 21 young children with acute respiratory pathology and in 10 children with communityacquired pneumonia, indicators of one-stage thermo- and oximetry of the extremities were studied and the data obtained were compared with the clinical features of the course of respiratory pathology.
