Haemodynamic parameters are significant markers for many medical fields. They could be used, for example, as markers of tissue perfusion adequacy, as predictive markers of several cardiovascular diseases or as stability markers in intensive care. Although there are many methods for estimating hemodynamic parameters, their correct determination is still a topical issue. Proper determination of haemodynamic parameters and research of new procedures, devices, contexts and interpretations are still needed. The proposed speech deals with the current problems and perspectives of haemodynamic parameters determination. The basic methods for measuring blood pressure will be briefly introduced, and their problems will be discussed in more detail. For the auscultatory method, the problems of routine blood pressure measurement will be introduced; the effect of the cuff deflation rate and the size of the cuff on the measurement accuracy will be discussed in detail. For the oscillometry method, the problem of artefacts in the oscillometry pulsations signal will be presented. The difference in mean arterial pressure (MAP) measured by oscillometry during inflation and deflation of the cuff for young and elderly people will be presented in the second part. The potential effect of this difference on the accuracy of blood pressure determination will be discussed in more detail. Consequently, the current topic of pulse wave velocity (PWV) determination using the occlusion technique will be introduced. And finally, the optical methods for non-invasive blood pressure measurement will be discussed. In both cases, the aim is to find a simple, fast and affordable way to determine selected hemodynamic parameters, either in clinical practice or everyday life. Monitoring selected hemodynamic parameters enables early detection of patients at risk of cardiovascular failure anyway and helps prevent life-threatening situations.
