Normal arteries: Sharp, high-pitched sound, bi- or triphasic. The second sound represents backward flow. Small digital arteries may be monophasic because they are too small and blood flow at this level is too smooth for backward flow.
Abnormal arteries: Monophasic, lower-pitched, longer “swishing” sound. This indicates an occluded vessel or collateral flow.
