ABSTRACT
It is known that the oxygen saturation of the peripheral blood is determined by the efficiency of the heart, the state of the microcirculatory bed, so position-dependent fluctuations in systolic blood pressure, pressure in the left renal and left adrenal veins, mediated bursts of hormones of the adrenal cortex can affect SO2.There is every reason to believe that SO2 will change in different static positions. Aim. To study position-dependent changes in oxygen saturation based on the study of the pathogenetic effect of venous blood flow in the "pool" of the left renal vein on the general hemodynamics and hormones of the adrenal cortex. Material and methods. A method for the polypositional assessment of oxygen saturation disturbances in six static states has been developed: standing, sitting, on the back, on the abdomen, on your right side, on your left side. Statistical data processing was carried out, which made it possible to determine the relationship between the indicators. Results. Polypositional studies of oxygen saturation hemodynamic parameters (SpO2) in six static states revealed the variability of the relationships of these groups when comparing them. The correlation was high, statistically significant between diastolic (DBP) and systolic (SBP) pressure, moderate between pulse (Ps)and SBP, pulse and DBP, weak between pulse and saturation. The groups divided by body positions relative to the pulse, SBP and DBP did not have a cluster structure. In the pron-position, SO2 had a minimal value, significantly different from the data in the other positions. Conclusion. Body position is one of the pathogenetically significant factors regulating blood oxygen saturation, which can help in the treatment and rehabilitation of patients with respiratory failure (COVID-19). Polypositional saturation measurement in six static states can determine a new, more effective algorithm for the management of patients with respiratory failure, both during treatment and during rehabilitation. © 2021, The authors This is an open article under the CC BY license.
