We have searched to define the major arterial parameters that determine aortic systolic (Ps) and diastolic (Pd) pressure in the dog. Measured aortic flows were used as input to the 2-element windkessel model of the arterial system, with peripheral resistance calculated as mean pressure divided by mean flow and total arterial compliance calculated from the decay time in diastole. The windkessel ...

Pulse wave analysis (PWA) allows estimation of cardiac output (CO) based on continuous the arterial blood pressure (AP) waveform. We describe physiology AP waveform, basic principles PWA algorithms for CO estimation, and technologies available clinical practice. The waveform is a complex physiological signal that determined by interplay left ventricular stroke volume, systemic vascular resistan...

The pressure-volume relationship in the ascending aorta ("windkessel") of the hooded seal was determined and the morphology of its vasa vasorum described in some detail. We found that the ascending aorta has a high compliance and can easily accommodate the entire stroke volume when the peripheral vascular resistance becomes much increased and maintain perfusion pressure during the much extended...

Human blood pressure (BP) and its pulse wave has always been a popular topic since it’s bound up with the heart related risks. In this paper, we mainly focus on of brachial artery which is also widely used in measurement BP, hence constructed artery-based system by using multi-Windkessel model managed to generate reliable signal adjustable authentic human parameters. On basis, filtering techniq...

In the resonance theory, the radial dilatation is emphasized, and the blood pressure wave is transmitted in the form of “moving windkessel”. Based on this conjecture, we developed a semi-empirical procedure to describe the pressure distribution in a complex simulated model composed of a main tube and attached organs. Now we try to apply this fitting method to hemodynamics in vivo, and we tested...
