What is the major difference between protocols for cardiac treadmill and claudication treadmill
testing? - answer✔Speed is varied during a cardiac treadmill test to increase heartrate to a
specific target level.
During a treadmill test, patient complains of pain in the left arm and jaw, but denies any other
pain. What is the most likely consideration? - answer✔Angina.
What is the normal diameter for the abdominal aorta? - answer✔2-3 cm.
After walking 5 minutes on treadmill, patient experiences decrease in ankle pressure of 40% on
right and 15% on left. These findings suggest? - answer✔Claudication.
What is the correct setting for arterial volume recording? - answer✔AC-coupled output.
What Doppler waveform abnormality in the lower extremity arterial circulation distal to a
hemodynamically significant stenosis show? - answer✔An absent flow recersal component,
blunting of the peak velocity and prolonged upslope and downslope.
A normal arterial volume waveform may have all EXCEPT: Swift upstroke, sharp peak, rapid
downslope bowed toward baseline, dicrotic notch or reverse flow component? - answer✔Reverse
flow component because it is part of a Doppler waveform not volume waveform.
T or F- Most analog Doppler analysis is qualitative, assessing for presence or absence of
characteristics. - answer✔True.
What is the normal response of ankle pressure to exercise testing? - answer✔There should be no
change if normal.
With severe lower extremity arterial occlusive disease, how will distal Doppler waveforms
appear? - answer✔Markedly dampened, possibly making interpretation difficult for distal
segments.
What is the usual cuff pressure used in arterial volume recording? - answer✔65 mmHg.
T or F- Diastolic flow reversal is always present in all abnormal limbs. - answer✔False. It may
be absent in vasodialted limbs.
What is the most important reason Doppler evaluations should be performed with patient in a
basal state and warm temperature? - answer✔The results are influenced by the patient's
peripheral resistence.
Audible Doppler venous signals are usually low frequency and vary with respiration, where as
normal arterial signals in the arms and legs are __________________. - answer✔Relatively high
frequency with pulsatile components and dont change with respiration.
When listening with CW Doppler over a stenotic lesion you will hear high frequency or low
frequency sound? - answer✔High frequency.
A normal PORH (postocclusive reactive hyperemia) response is a major velocity increase of
what percent increase in mean velocity? - answer✔>100%.
What are falsely elevated less frequently than tibial ankle pressures? - answer✔Toe pressures.
How can a PTFE graft be identified during ultrasonographic imaging? - answer✔A double line
appearance of the graft walls.
Velocities measured in a reversed saphenous vein bypass graft are usually ___________
proximally and ____________ distally. - answer✔Higher, lower.
The volume flow rate in a reversed saphenous vein bypass graft should be? - answer✔The same
throughout the graft even though the velocities may differ.
With both arterial obstructive disease and distal ischemia, what happens to vessel size and distal
resistance? - answer✔Vasodilation opens to attempt to increase nutrive blood flow to the
extremity and distal resistance decreases.
When you have a damped Doppler velocity waveform of the subclavian artery, where would the
significant lesion be located? - answer✔Proximal to the point of insonation.
Normal values in TcPO2 are _________. - answer✔60-80 mmHg.
AAA evaluation is done pre or post prandial and why? - answer✔Preprandial to minimize
shadowing due to bowel gas.
