Baroreceptor Gain (Overall) Factor
The Baroreceptor Gain (Overall) Factor parameter adjusts the influence of mean arterial pressure
(MAP) on heart rate, contractility, systemic vascular resistance and venous capacity. Use this
parameter to adjust how vigorously the heart and vasculature respond to blood pressure changes.
The degree of increase in heart rate or vascular response is influenced by the baroreceptor gain
(overall) factor.
For example, when blood pressure falls, the heart rate increases, the arteries increase their vascular
tone (resistance) and there is less pooling of the blood in the venous system, all in an attempt to
maintain adequate blood pressure. A baroreceptor gain (overall) factor value of less than 1
corresponds to baroreceptor depression. A baroreceptor gain (overall) factor value greater than 1
leads to a stronger response to MAP changes.
Default: 1
Range: 0.00 - 100.00
Baroreceptor Gain (Cardiac) Factor
The Baroreceptor Gain (Cardiac) Factor parameter selectively adjusts the influence of mean arterial
pressure (MAP) on the heart rate and contractility, influencing how much the heart rate increases or
decreases with changes in blood pressure. Use this parameter to adjust how vigorously the heart
responds to blood pressure changes.
A baroreceptor gain (cardiac) factor of less than 1 corresponds to baroreflex depression (e.g., less
heart rate response to MAP changes). A value greater than 1 leads to a stronger response to MAP
changes.
Default: 1
Range: 0.00 - 10.00
Baroreceptor Gain (Peripheral) Factor
The Baroreceptor Gain (Peripheral) Factor parameter adjusts the influence of mean arterial
pressure (MAP) on systemic vascular resistance and venous capacity, influencing how much the
vasculature responds to changes in blood pressure.
For example, when blood pressure falls, the arteries increase their vascular tone (resistance), and
there is less pooling of the blood in the venous system, in an attempt to maintain adequate blood
pressure. A factor of less than 1 corresponds to baroreflex depression (e.g., less systemic vascular
resistance response to MAP changes). A value greater than 1 leads to a stronger response to MAP
changes.
Default: 1
Range: 1.00 - 10.00
