"WebJun 21, 2024 · Next to the absolute values, it is also possible to measure the ratio between the systolic and diastolic velocities. If the peak diastolic velocity is more than 50% of the peak systolic velocity, the flow pattern is restrictive. If this ratio is less than 50%, the flow pattern is pulsatile suggesting hemodynamically significant PDA. " - Diastolic velocity ratio
