Left Ventricle Contractility Factor
The Left Ventricle Contractility Factor parameter adjusts the contractility of the left ventricle and
has a direct effect on cardiac output and blood pressure. Use this parameter to raise or lower the
cardiac output.
Default: 1
Range: 0 - 10.00
Right Ventricle Contractility Factor
The Right Ventricle Contractility Factor parameter adjusts the contractility of the right ventricle
and has a direct effect on pulmonary artery pressure and an inverse effect on central venous
pressure. Use this parameter to raise or lower pulmonary artery pressure (PAP) or to change the
central venous pressure (CVP).
Default: 1
Range: 0 - 10.00
Systemic Vascular Resistance Factor
The Systemic Vascular Resistance Factor parameter adjusts the baseline systemic vascular resistance.
Raising the value increases the systemic vascular resistance while lowering the value decreases the
vascular resistance.
Raising the parameter value is analogous to increasing the resistance to blood flow through the
systemic vasculature. Under such conditions, the arterial blood pressure (ABP) increases, and the
heart rate may decrease due to feedback from the physiological control mechanisms.
Default: 1
Range: 0.10 - 10.00
Venous Capacity Factor
The Venous Capacity Factor parameter adjusts the volume of blood contained in the unstretched
venous system without an increase in venous pressure. Raising the value decreases the venous
capacitance (vasodilatation and decreased vascular tone), while lowering the value increases the
venous capacitance (vasoconstriction and increased vascular tone).
The volume of blood in the venous system has an inverse relationship to the blood pressure.
Lowering the value is analogous to a “shift” in blood from the venous system to the arterial system,
and this shift, when coordinated with increased systemic vascular resistance, results in an increase in
blood pressure [arterial blood pressure (ABP), pulmonary artery pressure (PAP) and central venous
pressure (CVP)].
Default: 1
Range: 0.10 - 100.00
