Arterial Physiologic Testing

Question 1

sphygmomenometer has been used for determining

Answer 1

blood pressure

Question 2

physiologic/non-imaging techniques provide ___ and only detects ___

Answer 2

provide functional information about blood flow
only detects significant disease

Question 3

physiologic/non-imaging techniques tell us (6)

Answer 3

1. presence of significant disease
2. relative severity of disease
3. functional impairment
4. if symptoms are due to vascular insufficiency
5. digit measurements
6. healing potential

Question 4

physiologic testing methods (4)

Answer 4

Doppler waveform analysis
segmental pressure assessment
exercise testing
plethysmography - PVR, PPG

Question 5

physiologic testing methods determine

Answer 5

presence, severity, and general location of PAD

Question 6

volume plethysmography (PVR) reflects

Answer 6

amount of blood moving under a cuff

Question 7

photoplethysmography (PPG) assesses

Answer 7

cutaneous blood flow

Question 8

single level evaluation determines

Answer 8

presence and relative severity of disease (ABI)

Question 9

multilevel evaluation determines

Answer 9

presence and relative severity
as well as the region of disease

Question 10

physiologic testing limitations (3)

Answer 10

1. detects only significant disease
2. cannot distinguish stenosis from occlusion
3. provides the region but not the precise location of disease

Question 11

physiologic testing appropriate indications (8)

Answer 11

1. claudication
2. ischemic rest pain
3. arterial ulceration
4. PAD
5. suspected arterial embolization
6. pre-procedure assessment (stent, graft)
7. post-procedure follow up
8. prognosis for healing (ulcerations, amputation)
