Question # 1 (open the ZIP File)

Answer all the questions from the attached files. I’ve not enough time to do it myself. Please don’t use online sources.

• 1)Discuss the physiologic process behind blood flow in the human body. What makes it possible?
• 2)Name and describe the two types of laminar flow. How are they related to friction?
• 3)Define helical flow and give an example of where it can be frequently found.
• 4)Describe the components that contribute to turbulent flow. How are they related to friction?
• 5)Define Poiseuille’s Law. What does it tell us about flow?
• 6)Define Bernoulli’s Law. What does it tell us about flow?
• 7)How does Ohm’s Law relate to ultrasound?
• 8)Review arterial anatomy down to the capillary bed. Review arterial resistance in the lower extremity; Include normal at rest, normal in exercise and abnormal Doppler waveforms.
• 9)What is the difference in the capillary bed between exercise and chronic disease?
• 10)Define Atherosclerosis and how it contributes to Peripheral Arterial Disease (PAD)
• 11)List and describe the different severity levels of PAD and the expected clinical findings and sonographic findings associated with them.
• 12)How is AT (acceleration time) helpful in evaluating disease? Where?
• 13)Explain the mapping of a hemodynamic Stenosis in the lower extremity exam.
• 14)How is the systolic velocity ratio helpful in quantifying % Stenosis in the lower extremity?
• 15)Describe the sonographic findings of a total arterial occlusion in the lower extremity.
