Doppler ultrasound uses reflected sound waves to assess blood flow through a vessel. In this activity, you will use a Doppler device to listen to blood moving through the vessels of the arm and ankle, and use systolic pressure values to compute an ABI. View the list of pulses you located in Activity 4.3.4.

The Doppler Effect: Ultrasound Extension. The Doppler effect is used extensively in ultrasound imaging. Ultrasound machines can be used to measure blood flow rates by utilizing the fact that waves reflect off moving targets differently than stationary ones. Blood flow rates are calculated by placing the transducer above a blood vessel.

A Doppler ultrasound of the lower extremity. Given the high index of suspicion, you need to further evaluate this patient in order to comfortably rule out a DVT. Some studies have suggested that the negative predictive value of D-dimer is only ~80% among patients with a high pretest likelihood of DVT.

The Doppler transducer is positioned with the transducer directed proximally so that arterial flow will move directly into the ultrasound beam at an angle of 40-60 degrees. Appropriately sized cuffs should be placed on the thigh (choose three cuff or four cuff method: one thigh cuff for three cuff method; two for four cuff method), upper calf ...
