Guided Learning: Peripheral Artery Disease

Guided learning questions provide a systematic approach to learning by using a sequencing of the questions similar to how a topic would unfold in a traditional textbook. These guided learning questions assume the student is already knowledgeable of the content associated with hemodynamics and blood flow guided learning topics. The student is encouraged to go not only to the initial link associated with each learning question, but also to use embedded hyperlinks to expand upon the physiological concepts associated with the question.

At the end of the guided learning questions, there is a link to an external website (testmoz.com) that has multiple choice and true/false questions that are associated with the topic. When the quiz results are given to the user after taking the quiz, links are provided back to specific cvphysiology.com pages to assist in learning. Users need to register (free) on the testmoz.com site to access the quiz questions for the tutorial. No personal information is available to cvphysiology.com apart from the user provided login name and analysis of user performance on the quiz questions. This feedback is used to improve cvphysiology.com content and quiz questions.

Guided Learning

  1. What is the relationship between pressure, flow and resistance under laminar flow conditions, and how is this relationship altered by turbulent flow?
  2. How do changes in vessel radius alter single vessel resistance?
  3. What is a “critical stenosis” and why are large reductions in vascular radius required to reduce resting and maximal distal flows?
  4. How does the arterial anatomy of the leg affect the distribution of flow and pressure within the leg?
  5. What are the hemodynamic consequences of single and multiple stenotic lesions in the leg?
  6. Why might resting blood flows within a limb be normal despite significant proximal stenotic lesions?
  7. How do autoregulation of blood flow and vascular collateralization alter resting and maximal blood flow within the leg?
  8. What is active hyperemia and what mechanisms may be responsible for this phenomenon?
  9. What is the ankle pressure index? What is its normal value and under what conditions will this index fall during exercise and post-exercise?
  10. What is the hemodynamic basis of “vascular steal?”
  11. What is “intermittent claudication?"
