Vascular Ultrasound Exam Study Guide
Questions and Correct Answers
Kinetic Energy (KE) Ans: Energy from blood motion; increases
with velocity.
Potential Energy (Pressure) Ans: Stored energy due to heart
pumping; maintains perfusion.
Gravitational (Hydrostatic) Energy Ans: Affects pressure based on
body position.
Viscous Losses Ans: Due to friction between blood cells and
vessel wall; seen in long, straight vessels.
Inertial Losses Ans: Occur when blood flow changes direction or
speed, such as at a bifurcation or stenosis.
Turbulent Losses Ans: Occur post-stenosis; energy lost as
sound/vibration (bruit, thrill).
Hydrostatic Pressure Ans: Pressure exerted by a fluid due to
gravity.
Heart Valves Ans: Prevent backflow, ensure unidirectional blood
flow.
