What is the major difference between protocols for cardiac treadmill and claudication treadmill testing?
- Answers 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? - Answers Angina.
What is the normal diameter for the abdominal aorta? - Answers 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? - Answers Claudication.
What is the correct setting for arterial volume recording? - Answers AC-coupled output.
What Doppler waveform abnormality in the lower extremity arterial circulation distal to a
hemodynamically significant stenosis show? - Answers 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? - Answers 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. -
Answers True.
What is the normal response of ankle pressure to exercise testing? - Answers There should be no change
if normal.
With severe lower extremity arterial occlusive disease, how will distal Doppler waveforms appear? -
Answers Markedly dampened, possibly making interpretation difficult for distal segments.
What is the usual cuff pressure used in arterial volume recording? - Answers 65 mmHg.
What would the CFA signal look like with aortoiliac occlusion? - Answers Low pitched and monophasic.
T or F- Diastolic flow reversal is always present in all abnormal limbs. - Answers 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? - Answers 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 __________________. - Answers 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? - Answers High frequency.
A normal PORH (postocclusive reactive hyperemia) response is a major velocity increase of what percent
increase in mean velocity? - Answers >100%.
What are falsely elevated less frequently than tibial ankle pressures? - Answers Toe pressures.
How can a PTFE graft be identified during ultrasonographic imaging? - Answers A double line appearance
of the graft walls.
Velocities measured in a reversed saphenous vein bypass graft are usually ___________ proximally and
____________ distally. - Answers Higher, lower.
The volume flow rate in a reversed saphenous vein bypass graft should be? - Answers 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? - Answers 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? - Answers Proximal to the point of insonation.
Normal values in TcPO2 are _________. - Answers 60-80 mmHg.
AAA evaluation is done pre or post prandial and why? - Answers Preprandial to minimize shadowing due
to bowel gas.
What waveforms will you likely see from CFA to tibial arteries with a superficial femoral artery
occlusion? - Answers Triphasic CFA and proximal SFA with monophasic at the popliteal and tibial
arteries.
When calculating the ABI pressure ratio, what pressures are used? - Answers Ankle pressure/The higher
arm pressure.
Which ABI would be higher between Claudication and rest pain? - Answers Claudication is higher (0.5-
0.9)
Rest pain is lower (< 0.5)
What happens to a patients digital pressures when the hand is immersed in cold water if they have
Raynaud's disease? - Answers They decrease or disappear all together.
Define coarctation of the aorta. - Answers Coarctation of the aorta is a narrowing of the aorta most
commonly found just distal to the origin of the left subclavian artery.
