Non Invasive Vascular Screening

Question 1

Visual Inspection

Answer 1

Skin

• Discoloration

Dry cracked

Dermatitis

Vein distention, lipodermiatosclerosis

Edema

Question 2

Capillary Refil

Answer 2

Microvascular system

• press end of toe/proximal to wound

< 3 seconds

Question 3

Rubor of Dependency

Answer 3

• Supine LE elevated 30-60

Observe for pallor/blanching

• normal = little to no change

Mild to moderate = 45-60

severe = 25 seconds or less

• LE in dependency

Observe color

• <15 seconds to pink = normal

>30 and dark = reactive hyperemia

Question 4

Venous Filling Time

Answer 4

Supine LE elevated 30-60 degrees

• observe the veins drain out on top of foot 60 seconds
• normal 5-15 seconds

>20 seconds indicates arterial disease

Question 5

ABI

Answer 5

Ratio of ankle systolic to brachical systolic pressure

• >1-2 unreliable

1-1.2 NORMAL

.8-1.0 = Mild PAD

.5-.8 = Moderate PAD

<.05 Sever ischemia

<.2 Tissue death

Question 6

Claudicaition onset time

Answer 6

Walk on treadmil 1mph level

Record time for onset pain

Use for developing progressive walking program

tracking improved ambulator endurance
