Q

Exercise Management

Intermittent Walking Technique

A

Walk until moderate to near maximal Claudication pain.
Rest briefly at sever claudication symptoms.
Rest in sitting or standing position.
Restart walking when claudication symptoms are tolerable.

Q

Recommendations

A

Exercise increases walking time in pts with claudication
ASA reduces risk of serious vascular events
Most reliable physical findings: absent pedal pulse, femoral artery bruit, abnormal skin color, cool skin temp
Pts w/PVD and high chol should be tx’d with diet modifications and lipid lowering agents as needed
Pursue aggressive BP reduction
Duplex ultrasonography, MRA, and angiography are indicated for determining lesion localization and are best used when invasive intervention is a possibility
