Segmental Arterial Pressure
Aka: Segmental Arterial Pressure
- See Also
- Ankle-Brachial Index
- Technique
- Measure highest systolic reading in both arms
- Record first doppler sound as cuff is deflated
- Record at the radial pulse
- Use highest of the two arm pressures
- Measure highest systolic reading at 4 points per leg
- Cuff Locations
- High Thigh
- Low Thigh
- Calf (below knee)
- Above ankle
- Record first doppler sound as cuff is deflated
- Record at dorsalis pedis or posterior tibial pulses
- Calculate ratio of leg to brachial Blood Pressure
- Divide each leg cuff by highest brachial pressure
- Use similar method as in Ankle-Brachial Index
- Consider repeating above readings after Exercise
- Patient walks until absolute Claudication distance
- Interpretation: Findings suggestive of Occlusion
- Proximal lower extremity pressures less than arms
- Proximal femoral pressure <20 mmHg over brachial
- Drop in doppler pressures between segments >20-30 mmHg
