NON INVASIVE VASCULAR TESTING

Question 1

what are the types?

Answer 1

ABI/TBI
pulse volume recordings
segmental limb pressures
skin perfusion pressure
TcPO2

Question 2

simple test used to ID patients with PAD?

Answer 2

ABI

Question 3

ABI>1.40

Answer 3

non compressible vessels

Question 4

ABI 1 to 1.40

Answer 4

normal

Question 5

ABI 0.9 to 0.99

Answer 5

borderline

Question 6

ABI < 0.9

Answer 6

abnormal

Question 7

TBI <0.70 is considered?

Answer 7

diagnostic PAD

Question 8

TBI<0.25 is considered?

Answer 8

sever PAD

Question 9

aka segmental plethysmography?

localize level of PAD
measures segmental limb systolic pressures
drop of 20-30 mm Hg
affected by non compressible vessels

Answer 9

segmental limb pressure

Question 10

aka pulse volume plethysmography

volume of change in limb at each pulse beat

waveforms have a sharp upstroke

dicrotic notch lost first, then flattening of the upstroke

not affected by non compressible vessels

Answer 10

pulse volume recording

Question 11

microcirculatory assessment tool that can help assess wound healing potential

assesses capillary perfusion

SPP<30 mmHg have a low prob of wound healing

Answer 11

skin perfusion pressure

Question 12

aka TCOM or TCPO2

helps predict presence of vascular disease

normal is? what needs a vascular consult

used to evaluate if HBO therapy may be beneficial

Answer 12

transcutaneous oxygen measurement

60 mm Hg
30 mm Hg or less

Question 13

what are the noninvasive tests?

Answer 13

arterial duplex ultrasonography

magnetic resonance angiography

computed tomographic angiography

Question 14

what are the invasive arterial studies?

Answer 14

ordered by cardiologist

contrast angiography the gold standard for vascular evaluation
