Use appropriate duplex instrumentation with appropriate frequencies for the vessels being examined.

• Typically a linear 5-7 MHz transducer
  • Superficial structures may require higher frequency
  • Deeper structures or edematous tissue may require a lower frequency transducer
  • Iliocaval imaging will require lower frequency 2-5 MHz curved linear or phased array transducers.
• Display of two-dimensional structure and motion in real-time
  • Doppler ultrasonic signal documentation
  • Spectral analysis with color and/or power Doppler imaging
• Digital storage capabilities of ultrasound image

Other non-imaging equipment:

• The use of a rapid cuff inflator can be used in place of manual augmentation.
