OXYGEN SATURATION BLOOD IN PATIENTS WITH PSORIATIC ONYHODISTROPHY
The results of an experimental measurement of the degree of hemoglobin oxygen saturation (saturation, SpO2) were analyzed in groups of patients with psoriatic onychodystrophy manifestation and without pronounced disorders of the nail plates against the background of individuals without chronic skin diseases (healthy) long time living in Surgut and Surgut district of the Khanty-Mansiysk Autonomous Okrug. The purpose of research was to identify features in terms of blood saturation of patients with psoriatic onychodystrophy in the nail phalanges. A total of 30 patients with psoriasis were examined, as well as data from 15 healthy people (without skin diseases), who made up the control group in terms of the degree of blood oxygen saturation. An experimental study was conducted using a non-invasive method using the Elox-01C3 instrument complex, equipped with a special computer program that allows real-time display of the dynamics of the blood saturation indicator (SpO2, %) of the subject with visualization of a digital picture on the screen. We used mathematical processing of data using the one-sample Student's t-test to test the hypothesis of the presence (absence) of statically significant differences in the mean values of data in the compared groups of individuals. It was revealed that patients with psoriatic onychodystrophy had a lower oxygen content in the nail phalanges of the fingers, which was confirmed by statistically significant differences. This fact indicates the important role of the identified changes in the pathogenesis of these manifestations of the disease and opens up prospects for the development of treatment methods.
