The Windkessel analogy illustrated. Windkessel effect (German: Windkesseleffekt) is a term used in medicine to account for the shape of the arterial blood pressure waveform in terms of the interaction between the stroke volume and the compliance of the aorta and large elastic arteries (Windkessel vessels) and the resistance of the smaller arteries and arterioles.
The lumped parameter model consists in a system of ordinary differential equations that adhere to the principles of conservation of mass and momentum balance. The model is obtained exploiting the electrical analogy where the current represents the blood flow, the voltage represents the pressure difference, the electric resistance plays the role of the vascular resistance (determined by the ...
Frank also did work on the oscillatory characteristics of the auditory apparatus of the ear and the thermodynamics of muscle. He also worked extensively on developing accurate methods to measure blood pressure and other physiological phenomena (e.g. Frank's capsule (Frank-Kapsel), optical Spiegelsphygmograph).
The most common outlet boundary conditions used are the two and three-element Windkessel models. [2] The two-element Windkessel model replicates viscous resistance immediately downstream from the outlet and the three-element Windkessel model accounts for the resistance of capillaries and venous circulation.

7 Blood Pressure Mistakes That Could Be Throwing Off Your Readings. In 2022 — the most recent year for which mortality data is available — a total of 941,652 people died of heart disease ...
The major body fluid which acts as the lifeline of the living organisms is "Blood". Blood is an extremely complex biological fluid. It consists of blood cells suspended in plasma and other different types of cells which include white blood cells, platelets etc. The blood flow in arteries and veins are closely linked to the blood vessel properties.
