The physical parameters estimation of physiologically worked heart prosthesis

Intravascular low-power laser illumination through special fiber diffusers

“…The plaque narrows disease-changed vessels. This process affects the whole arterial system but it is especially dangerous when coronary arteries are affected as that causes acute coronary syndromes [1][2][3]. There are many procedures available to increase arterial blood flow and to limit the danger of already formed atherosclerotic plaques.…”

Theoretical and model analysis of the unreliability of cardiac output measurement by means of the thermodilution method

“…Available flow measurement methods (e.g. transit time ultrasound flow meter equipped with a vascular probe) are not accurate enough (the unreliability of Transonic TS420 reaches 5% after in-situ calibration [9,16,19,22,23]). Moreover, the measurement itself requires serious interference in the measured object (intubation, anesthesia and thoracotomy).…”

“…It is monitored in the course of intensive therapy in order to check the progress and treatment of illness . Cardiac output is also estimated during mechanical heart supporting therapy [16,18,19,[22][23][24]. In other applications this parameter is used for numerical and physical modeling of the human circulatory system [17].…”

Preliminary Research Concerning Measurements οf the POLVAD Blood Chamber Volume Based οn Helmholtz's Acoustic Resonator Principle

“…Nowadays many efforts are taken with the purpose of effective solutions of problems concerning elaboration of the artificial heart [1][2][3][4][5][6][7][8][9][10]. It is caused by an alarming increase of the number of people suffering from heart diseases.…”
