16: ABI and Analog Pedal Artery Waveforms
Introduction
This chapter introduces ABI and Analog Pedal Artery Waveforms (ABI) — a simple, noninvasive test that compares the systolic pressure at the level of the ankle to the systolic pressure at the level of the brachial artery. Continuous-wave (CW) analog Doppler waveforms are recorded to support the pressure information.
Student Learning Objectives
By the end of this lesson, students will be able to:
- Explain the purpose and principle of lower-extremity ABI and analog pedal artery waveform testing.
- Identify appropriate indications and contraindications for the exam.
- Demonstrate proper cuff placement, Doppler probe selection, and technique.
- Interpret waveform patterns and pressure gradients.
- Recognize disease severity and differentiate normal from abnormal findings.
- Correlate physiologic results with clinical presentation and duplex findings.
