What is the purpose of physiologic arterial exam?
Presence Severity Location-of obstruction or occlusion (infrapop) Change Healing
What is the purpose of physiologic arterial exam?
Presence Severity Location-of obstruction or occlusion (infrapop) Change Healing
What are the 4 arterial physiologic techniques?
ABI Segmental Pressures CW Doppler VPR (Segmental plethysmography) *These techniques only evaluate hemodynamically significant obstructions >50%
Why do we use all types of exams?
Because using multiple physiologic exams improves accuracy vs just one test
Diagnostic ABI purpose
Presence
Severity
Change
ABI >.95
Normal-asymptomatic
ABI .80-.95
Mild-claudication
ABI .50-.79
Moderate-claudication
.30-.49
Severe-Possible rest pain
Critical-probably rest pain, gangrene, ulceration

What amount do we use to distinguish change happening in ABI?
> .15
What are some limitations of ABI tests?
Calcified arteries
Ulceration-can’t put cuffs or probe
Intolerance of pressure cuff
What are 3 segmental pressure locations of obstruction?
Aorto-Iliac
Femoral-Popliteal
Infrapopliteal
Segmental Pressure “Normal” Criteria
hint its a number
<20 mmHg
Seg Pressure Possible Obstruction
> 20-30 mmHg
Seg Pressure Probable Obstruction
> 30 mmHg
