The following waveforms were recorded from the right and left common carotid arteries of a patient during a Carotid Duplex. These waveforms indicate:  

A dampened waveform pattern is documented at the right ICA. What does this change in waveform pattern suggest?

What is the term for a fragment of atherosclerotic debris that courses distal through the vasculature until it lodges in a small vessel?

“Temporal tap” technique is accomplished by lightly taping over which vessel?

Where would a carotid body tumor be located?

Through auto-regulation of blood pressure, if blood pressure drops, what will be the normal response of the body to maintain blood flow volume?

A high resistant waveform, with low velocity, is identified at the right CCA. This most likely indicates a hemodynamically significant stenosis or occlusion of the:
