| Description
| - Pro simulaci průchodu pulsní vlny byla navržena experimentální linka. Jako vzorky byly použity latexové trubice s různými vnitřními průměry a tloušťkami stěn. Rychlost pulsní vlny byla měřena neinvazivní optickou metodou a ověřena invazivní metodou, měřením tlaku na začátku a konci trubice. Neinvazivní metoda je založena na optickém snímání radiálních posuvů pulsující stěny trubice. Pro snímání byla použita vysokorychlostní kamera se snímkovací frekvencí 1000 Hz. Pulsní frekvence proudění byla 80 pulsů/min. V lince byly nastaveny různé tlakové amplitudy. Vnější zatížení trubice bylo atmosférickým tlakem. K vyhodnocení naměřených dat byl vytvořen algoritmus v programu MATLAB. Obě experimentální metody (invazivní a neinvazivní) přinesly podobné výsledky. Naměřené rychlosti pulsní vlny byly v rozmezí od 4,5 do 6 m/s, tedy řádově stejně jako hodnoty založené na teoretickém odhadu (7,5 m/s) nebo podobná publikovaná fyziologická data. (cs)
- An experimental set-up was designed to study this phenomenon. Latex tubes with variable inner diameter and wall thickness were used as specimens. The pulse wave velocity in elastic tubes is measured by non-invasive optical method and verified by the invasive pressure method. The method is based on optical measurements of radial displacements of the pulsating tube wall. A crash test camera with high frame rate of 1000 Hz (fps) was used. The pulse rate of pulsatile flow was 80 pulses/min. Various pressure amplitudes were set. The elastic tube was loaded by atmospheric pressure from outside. The MATLAB software was used to create an algorithms for evaluation of the experimental data. The two experimental methods (non-invasive and invasive) showed similar results. The measured pulse wave velocities ranged from 4.5 to 6 m/s, thus in the same order of magnitude as values based on a theoretical estimation (7.5 m/s) and the physiological values published in literature.
