Arterial pulmonary conductivity

Modelling > Blood circulation parameters > Vascular parameters > Arteries > Arterial pulmonary conductivity

Notation in mathematical model	Y_HRAR
Allometric exponent	3/4

The parameter describes the dependence of blood flow through pulmonary valve from the difference between right ventricular pressure and arterial pulmonary pressure. 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_HRAR in the equation describing the blood flow through pulmonary valve (variant of the formula (20))

(32)

where P_HR - right ventricular pressure, P_AR - arterial pulmonary pressure.

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