Principle

This set-up shows how blood flow studies are performed using Doppler ultrasound (Doppler sonograph). On a realistic arm dummy, the differences between continuous (venous) and pulsating (arterial) flow are shown as well as the difference in flow through a normal blood vessel and a stenosis.

Benefits

  • Ideal experiment for medical students to learn the principles of Doppler sonography
  • True to life with an arm model with blood vessels and stenosis
  • Experiment components can also be used for other experiments relevant for medical students 
  • Display of measurement values as with a diagnostic system

Tasks

  1. Analyse blood flow and search positive and negative flow components. Explain the differences.
  2. Locate the built-in stenosis and compare the spectral distribution upstream and downstream of the stenosis.
  3. Examine and compare the three pulse modes of the pump.

Learning objectives

  • Venous flow
  • Arterial flow
  • Stenosis
  • Blood flow velocity tracings
  • Frequency shift
  • Doppler effect
  • Doppler angle
  • Doppler sonography
  • Colour Doppler
  • Continuity equation
