Document Summary
Primarily used in patients with intermittent claudication with normal or near normal abis at rest. Exercise stress can be obtained by treadmill testing, walking at patient"s own pace in corridor, or heel raises (toe-ups) Treadmill testing is performed following resting pressure measurements. Walking speed and incline should be noted, especially if patient is unable to tolerate standard settings. Study is terminated at 5 minutes or when patient indicates need to stop due to leg pain, shortness of breath, or other signs of distress. Pressures are typically repeated every 1 to 3 minutes until they return to baseline. Lowest value of post-activity abi categorizes functional severity of limb. Recovery time suggests whether paod is single or multilevel. Abi that returns the pre-exercise level within 5 minutes associated with single-level disease. Abi that returns to pre-exercise level > 10 minutes associated with multi-level disease post exercise. Volume plethysmographic waveforms can also be obtained to aid in interpretation.
