The ratio of stroke volume to pulse pressure correlates with arterial compliance and cardiac load.
Parameters:
(1) stroke volume in mL
(2) pulse pressure in mm Hg
pulse pressure =
= (systolic systemic arterial pressure) - (diastolic systemic arterial pressure)
stroke volume to pulse pressure ratio in mL per mm Hg =
= (stroke volume) / (pulse pressure)
A high ratio is associated with increased arterial compliance and reduced vascular resistance.
