Arterial systemic conductivity

Notation in mathematical model	Y_HLAL
Allometric exponent	3/4

The parameter describes the dependence of blood flow through aortic valve from the difference between left ventricular pressure and arterial systemic pressure (aorta and main arteries). Its physical meaning – a value inverse to resistance of the blood flow in the specified part of vascular system. The parameter is included in mathematical description of a law of blood flow through vessels as a factor Y_HLAL in the equation describing the blood flow through aortic valve (variant of the formula (20))

(31)

where P_HL - left ventricular pressure, P_AL - arterial systemic pressure.

The parameter is used for modelling of pathologic mode “aortic stenosis”. The main characteristic of this mode a reduction of conductivity value in comparison with its normal value. The regurgitation factor in the aortic valve r_HLAL is used for modelling of pathologic mode "aortic valve failure".
