WebAug 26, 2024 · What is triphasic Doppler? This elastic recoil pushes the blood forward again giving the Doppler noise we hear a third component (triphasic). If the artery being listened to has a severe blockage, the arterioles will open (vasodilation) to allow more flow in an attempt to deliver the amount of blood required by parts of the body downstream.
