Question | Answer |
Which type of flow has higher velocities mid-stream and lower velocities toward the vessel wall? | laminar flow |
According to the Bernoulli's Principle, what happens to the velocity as the diameter of the vessel decreases? | the velocity will increase with a decrease in diameter |
Let's say your patient is a diabetic and the PTAs and dorsalis pedis are difficult to hear on doppler. What lateral calf artery can you Doppler instead? | the peroneal artery |
True or false. When resting, the arteries in the leg should be triphasic. | true |
When exercising, what happens to the arterial flow in the legs? | It becomes more continuous and low resistant compared to the triphasic flow when resting. Vasodilation occurs to pool more blood to the legs. |
True or false. A reason for a venous LE study to be done is if the patient is experiencing intermittent leg pain while walking. | false; that is an arterial symptom |
Analog Doppler cannot detect velocities less than ____ cm/sec. | six |
Does triphasic flow have a high or low PI? | high |
Describe the waveform of a monophasic signal distal to an obstruction. | tardus parvus, continuous, low velocities, slow AT |
True or false. When doing segmental pressures, which level/location of the cuffs should be inflated first on the legs? | the ankles |
