What are ABPI & Toe Pressures
ABPI (Ankle Brachial Pressure Index) and Toe Pressures are non-invasive vascular assessment tests that measure blood flow and circulation in your lower extremities. These diagnostic procedures help identify peripheral arterial disease (PAD), assess wound healing potential, and monitor the effectiveness of circulation treatments. By comparing blood pressures at different points in your legs and feet, we can detect blockages or narrowing in your arteries.
Specialist Services
What the Service Includes
Ankle Brachial Pressure Index (ABPI)
- Blood pressure measurements taken at the ankle using a Doppler ultrasound device
- Arm blood pressure measurement for comparison
- Calculation of the pressure ratio between ankle and arm
- Assessment of arterial blood flow in the main vessels of the legs
Toe Pressure Measurements
- Specialized pressure cuffs applied to the big toes
- Photoplethysmography or Doppler assessment of toe circulation
- Measurement of systolic blood pressure in the digital arteries
- Evaluation of small vessel circulation in the feet
Comprehensive Vascular Assessment
- Visual examination of feet and legs for signs of poor circulation
- Assessment of skin color, temperature, and texture
- Evaluation of pulse strength in feet and ankles
- Documentation of any wounds, ulcers, or areas of concern
Results Analysis and Interpretation
- Detailed explanation of your test results and what they mean
- Risk stratification for peripheral arterial disease
- Recommendations for further testing or treatment if needed
- Coordination with other healthcare providers when appropriate

What to Expect During Your Appointment
Preparation for Your Visit
- Wear loose, comfortable clothing that allows easy access to your arms and legs
- Avoid smoking for at least 2 hours before the test (nicotine can affect circulation)
- Continue taking your regular medications unless specifically advised otherwise
- No special dietary restrictions are required
During the Assessment (typically 30-45 minutes)
- Initial discussion about your symptoms, medical history, and circulation concerns
- Comfortable positioning on an examination table
- Blood pressure measurement in both arms using a standard cuff
- Application of gel and Doppler probe to locate pulses at the ankles
- Pressure measurements taken at the posterior tibial and dorsalis pedis arteries
- Specialized toe cuffs applied for digital pressure measurements
- Brief rest periods between measurements to ensure accuracy
- Real-time explanation of findings during the procedure
After the Test
- Immediate results discussion with detailed explanation
- Written report of findings and recommendations
- Referral arrangements if additional vascular studies are needed
- Follow-up appointment scheduling if monitoring is required

Who Should Have This Assessment?
This testing is particularly important for individuals with:
Medical Conditions
- Diabetes mellitus
- High blood pressure
- High cholesterol
- History of heart disease or stroke
- Kidney disease
- Smoking history
Symptoms Suggesting Poor Circulation
- Leg pain when walking (claudication)
- Cold feet or legs
- Slow-healing wounds on feet or legs
- Changes in skin color or texture
- Weak or absent pulses in feet
- Numbness or tingling in extremities
Preventive Screening
- Adults over 50 with risk factors for vascular disease
- Anyone with multiple cardiovascular risk factors
- Patients requiring pre-operative vascular assessment
- Individuals with family history of peripheral arterial disease

Understanding Your Results
Normal ABPI Values (0.9-1.3)
- Indicates good arterial blood flow to the feet
- Low risk for peripheral arterial disease
- Normal wound healing potential
Abnormal Results
- ABPI below 0.9 suggests peripheral arterial disease
- Values below 0.5 indicate severe arterial insufficiency
- Toe pressures below 30mmHg suggest poor healing potential
- Further vascular evaluation may be recommended

The Importance of Vascular Health
Proper circulation is essential for foot health, wound healing, and overall well-being. ABPI and toe pressure assessments provide crucial information that helps prevent serious complications and guides appropriate treatment strategies. These simple, painless tests can identify problems before they become limb-threatening conditions.
