Abstract

Bolezni obtočil so glavni vzrok smrti v razvitih delih sveta. Obtočila so pod nadzorom avtonomnega živčevja, zato se preko monitoringa srca zagotovi pogled v avtonomno živčevje. Zgodnja preventivna intervencija s presejalnimi testi pomeni pravočasno zdravljenje in znižanje umrljivosti. Raziskovali smo, ali je mogoče z medicinsko opremo, ki je primarno namenjena neprekinjenemu monitoringu v bolnišničnem okolju, izvajati hitre dinamične provokacijske teste, ki bi nam služili kot presejalni testi. Hemodinamične spremenljivke smo zajemali s kontinuirano neinvazivno protitlačno Peňáz metodo merjenja krvnega tlaka. Okno v delovanje avtonomnega živčevja pa je predstavljala variabilnost frekvence srca (HRV). Na zdravih prostovoljcih smo izvajali dva tipa provokacijskih testov obtočil: Valsalva manever in pasivni dvig nog (PLR). Podatke smo analizirali z Matlab programskim orodjem. Na podlagi opazovanja vseh štirih faz Valsalva manevra smo ugotovili, da je oprema sposobna zabeležiti hiter dinamični odziv. PLR test pa je pokazal nekoliko manjšo občutljivost. Oprema bi ob zelo natančni standardizaciji lahko predstavljala orodje za presejalne teste.

Secondary title: ANALYSIS OF DYNAMIC PHYSIOLOGICAL RESPONSES IN NON-INVASIVE BLOOD PRESSURE MEASUREMENT WITH PENAZ BACK PRESSURE METHOD
Secondary abstract: Circulatory diseases are the main cause of death in the developed world. Circulatory system is under control of the autonomic nervous system, therefore through the cardiovascular monitoring we get an insight into the autonomic nervous system. An early intervention with preventive screenings ensures timely treatment and reduces mortality. We researched whether it is possible to perform fast dynamic provocation tests with the equipment that is primarly meant for uninterrupted monitoring in a hospital environment, and use these tests as screening assays. Hemodynamic variables were determined by the continuous noninvasive Peňáz backpressure method of measuring blood pressure. Heart rate variability (HRV) provided a window into the functioning of the autonomic nervous system. Using healthy volunteers, we carried out two types of challenge tests of the circulatory system: Valsalva maneuver and passive leg raising (PLR). Data were analyzed using the Matlab software tool. Our findings show that the equipment is able to record fast dynamic response, as we observed all four phases of Valsalva maneuver. PLR test demonstrated slightly lower sensitivity. With precise standardization the equipment could be used as a tool to perform screening assays.
