Vascular Testing Clinical Terminology
🩺 Vascular Testing Clinical Terminology
Essential terms for PAD testing and simpleABI systems
Testing Locations on the Body
Brachial
Upper arm
Radial
Wrist (thumb side)
Femoral
Upper thigh
Dorsalis Pedis
Top of foot
Posterior Tibial
Inner ankle
🎯 Key Measurements & Tests
Ankle-Brachial Index
[ANG-kul BRAY-kee-ul IN-deks]
A ratio comparing blood pressure in the ankle to blood pressure in the arm. The gold standard test for diagnosing PAD.
Resting ABI Normal Range:
>1 = Normal | 0.8-0.9 = Mild PAD | 0.5-0.8 Moderate PAD | <0.5 = Significant PAD
Toe-Brachial Index
[TOH BRAY-kee-ul IN-deks]
Ratio of toe systolic pressure to arm systolic pressure. Used when ABI results are unreliable due to calcified arteries.
When to Use:
Diabetic patients, elderly patients, or when ABI >1.3 (indicates calcified arteries)
Pulse Volume Recording
[PULS VOL-yoom ri-KORD-ing]
Measures volume changes in blood flow through limbs using inflatable cuffs. Creates waveform patterns showing blood flow quality.
Clinical Significance:
Evaluates blood flow patterns and can detect PAD even when ABI results are normal or unreliable
Segmental Pressures
[seg-MEN-tul PRESH-urz]
Blood pressure measurements taken at multiple levels of the leg to pinpoint the exact location of arterial blockages.
Clinical Value:
Helps determine precisely where blockages occur (thigh, calf, ankle) for targeted treatment planning
🏃♂️ Testing Maneuvers & Positions
Provocative Maneuvers
[pruh-VOK-uh-tiv muh-NOO-verz]
Physical movements or exercises designed to stress the vascular system and reveal symptoms that may not be present at rest.
Examples:
Hall walking, toe raises, ankle flexion exercises to provoke claudication symptoms
Dorsiflexion
[dor-si-FLEK-shun]
Bending the foot upward toward the shin, creating a 90-degree angle or less at the ankle.
Testing Purpose:
Helps locate the dorsalis pedis pulse and positions the foot for accurate pressure measurements
Post-Exercise ABI
[post EKS-er-sahyz ABI]
ABI measurement taken immediately after exercise to detect PAD that may not be apparent during rest testing.
Clinical Value:
Can reveal early-stage PAD when resting ABI appears normal (>20% drop indicates PAD)
🩸 Vascular Anatomy & Pulses
Dorsalis Pedis
[dor-SAL-is PEE-dis]
Artery and pulse point located on the top of the foot, running from the ankle toward the big toe.
Location Tip:
Found between the first and second toe tendons, about 1/3 down from ankle to toes
Posterior Tibial
[pos-TEER-ee-or TIB-ee-ul]
Artery and pulse point located behind the inner ankle bone (medial malleolus).
Location Tip:
Palpated in the groove behind the inner ankle bone, often easier to find than dorsalis pedis
Brachial Artery
[BRAY-kee-ul AR-ter-ee]
Major artery in the upper arm, used as the reference point for ABI calculations.
Testing Note:
Systolic pressure measured here serves as the denominator in ABI calculations
🏥 Clinical Conditions & Symptoms
Claudication
[klaw-di-KAY-shun]
Muscle pain, cramping, or fatigue in the legs during walking that goes away with rest. Classic symptom of PAD.
Patient Description:
"My legs hurt when I walk but feel better when I stop and rest"
Critical Limb Ischemia
[KRIT-i-kul LIM is-KEE-mee-uh]
Severe PAD with inadequate blood flow causing rest pain, non-healing wounds, or tissue death.
Urgency Level:
Medical emergency requiring immediate intervention to prevent amputation
Arterial Calcification
[ar-TEER-ee-ul kal-si-fi-KAY-shun]
Calcium deposits in artery walls making them stiff and incompressible, leading to falsely elevated ABI readings.
Testing Impact:
When ABI >1.3, consider TBI testing instead for accurate PAD assessment
🔍 Quick Reference for Reps
Normal ABI Range
0.9 - 1.3 (anything outside this range needs attention)
PAD Prevalence
200+ million worldwide, 8-12 million in US
Testing Time
A single-level simpleABI test takes 10-15 minutes
Key Selling Point
Early detection prevents amputations & heart attacks
Target Patients
50+ years, diabetics, smokers, family history
Reimbursement
Medicare/Insurance covered when medically necessary
