change in mean arterial blood pressure to change in intracerebroventricular sodium concentration ratio
A calculated measurement of the ratio between the change in mean arterial blood pressure and the concentration of sodium infused directly into the ventricle(s) of the brain; calculated as the slope of the curve of mean arterial blood pressure versus intracerebroventricular-infused sodium concentration.
