- Identification of good quality Doppler signals from brachial artery and pedal vessels.
- The distinction between normal and abnormal flow through audible Doppler signal.
- Accuracy of systolic pressure measurements from each location.
- Requirements for recording measurements.
- Calculation and documentation of ABPI from the recorded pressure measurements.
