Abstract:V magistrskem delu smo s pomočjo naprednega neinvazivnega hemodinamskega monitorja Osypka Medical Aesculon spremljali hemodinamske parametre glede na različne scenarije. Namen magistrskega dela je bil z izvedenimi scenariji ugotoviti spremembe v fizioloških procesih glede na zunanje dejavnike ter skladnost dobljenih rezultatov z rezultati iz literature. Meritve smo izvajali na skupini zdravih prostovoljcev (N = 8), ki smo jih izpostavili trem različnim scenarijem v skupnem številu 96 meritev. V prvem scenariju, pasivnem dvigu nog za 45°, nismo ugotovili skladnosti dobljenih rezultatov z rezultati iz primerjalne literature. Rezultati so odražali statistično nepomembno odstopanje vrednosti pri vseh štirih opazovanih parametrih: frekvenca srca - HR (p = 0,416), minutni iztis srca - CO (p = 0,575), srednji arterijski tlak - MAP (p = 0,671) in iztisni volumen srca - SV (p = 0,204). Pri drugem scenariju, izvedbi Valsalva manevra, smo ugotovili statistično pomembnejše odstopanje pri dveh opazovanih parametrih, in sicer pri CO (p = 0,012) in HR (p = 0,049). CO se je skladno s primerjalno literaturo znižal s 6,8 ± 1,4 na 5,0 ± 0,3 L/min, kar pomeni, da je povprečna vrednost znižanja znašala 1,7 ± 1,2 L/min. Prav tako se je pričakovano znižal tudi HR. Povprečna vrednost nižanja HR je znašala 15 ± 20 utripov/min, in sicer z 71 ± 18 na 56 ± 9 utripov/min. Pri tretjem scenariju, kjer smo izvedli potapljaški refleks, smo ugotovili skladnost s primerjalno literaturo samo v enem opazovanem parametru, in sicer HR (p = 0,012), ki se je znižal. Povprečna vrednost nižanja HR je znašala 13 ± 8 utripov/min, saj se je povprečna vrednost HR znižala s 77 ± 12 na 64 ± 14 utripov/min. Ugotovili smo, da pri nobenem izvedenem scenariju ni prišlo do statistično pomembnega odstopanja v MAP in SV, čeprav smo meritve izvajali večkrat, morebitne nepravilne meritve pa smo zavrgli. Prišli smo do zaključka, da je zanesljivost pri meritvah odvisna tako od natančnosti naprave kot tudi od zunanjih in notranjih dejavnikov, ki vplivajo na preiskovanca.

Title:The use of electrical cardiometry technology for physiologic monitoring
Abstract:In this research, we used advanced non-invasive hemodynamic monitor Osypka Medical Aesculon to observe hemodynamic parameters according to different scenarios. The purpose of this research was to identify changes in physiological processes through scenarios in relation to external factors as well as to determine the consistency of the results obtained with the results from the literature. Measurements were performed on a group of healthy volunteers (N = 8), which were exposed to three different scenarios in the total number of 96 measurements. In the first scenario, the passive leg raising 45°, we haven`t found the compliance of the results with the results from the reference literature. The results reflected a statistically insignificant deviation values of all four observed parameters: Heart Rate - HR (p = 0.416), Cardiac Output - CO (p = 0.575), Mean Arterial Pressure - MAP (p = 0.671) and Stroke Volume - SV (p = 0.204). In the second scenario, the implementation of Valsalva maneuver, we found a statistically significant deviation of two observed parameters: CO (p = 0.012) and HR (p = 0.049). The value of CO decreased consistently in comparison with the values from the literature that is from 6.8 ± 1.4 to 5.0 ± 0.3 L/min, which indicates that the median value of the reduction was 1.7 ± 1.2 L/min. An expected reduction in HR was also found. The median value of a decrease in HR was 15 ± 20 bpm, namely from 71 ± 18 to 56 ± 9 bpm. In the third scenario, where we performed the diving reflex, we found the compliance of the results with the results from the literature only in one observed parameter. It was the HR value (p = 0,012), which decreased. The median value of a decrease in HR was 13 ± 8 bpm because the median value of HR was decreased from 77 ± 12 to 64 ± 14 bpm. At none of the mentioned scenarios statistically significant deviation of MAP and SV occurred, although we did multiple measurements, and discarded potentially incorrect measurements. We have come to the conclusion that the reliability of the measurements depends on the accuracy of the device as well as on the internal and external factors that influence the subject under investigation.
Keywords:passive leg raising, hemodynamic parameters, non-invasive hemodynamic monitoring, Valsalva maneuver, diving reflex.
