A real ABI, with true VPR waveforms.
Smart-ABI is a wireless, point-of-care device that performs a true cuff-based, four-limb Ankle-Brachial Index in about five minutes, generating an ABI value plus volume plethysmography records (VPR) waveforms. Smart-ABI+ adds Toe-Brachial Index for the patients where ankle pressures fail.
Smart-ABI
Wireless, true cuff-based, four-limb ABI with VPR waveforms in about five minutes. The core of the family: fast, simple, and built for medical-assistant operation in any care setting.
Smart-ABI+
Everything Smart-ABI does, plus Toe-Brachial Index (TBI) for patients with incompressible ankle vessels, a common pattern in long-standing diabetes, chronic kidney disease, and advanced age, where ABI alone is insufficient.
Smart-ABI vs Smart-ABI+
Both run the same MA-operated workflow and feed the same EMR-ready report. The difference is TBI, which adds about two minutes.
| Capability | Smart-ABI | Smart-ABI+ |
|---|---|---|
| True cuff-based Ankle-Brachial Index (ABI) | ✓ | ✓ |
| Volume Plethysmography Records (VPR) waveforms | ✓ | ✓ |
| Four-limb, wireless measurement | ✓ | ✓ |
| Toe-Brachial Index (TBI) | — | ✓ |
| For incompressible ankle vessels (diabetes, CKD, elderly) | — | ✓ |
| MA-operated workflow | ~5 min | ~7 min |
| EMR-ready, color-coded reports (Smart-ABI Hub) | ✓ | ✓ |

When to use ABI, and when TBI.
Four indications for each index. Smart-ABI performs the ABI; Smart-ABI+ adds the TBI.
Ankle-Brachial Index (ABI)
Smart-ABI and Smart-ABI+
Peripheral Arterial Disease (PAD) Diagnosis
ABI is widely used to diagnose PAD, especially in patients with risk factors like diabetes, smoking, or hypertension. It helps in identifying arterial blockages that reduce blood flow to the lower limbs.
Cardiovascular Risk Stratification
ABI serves as an indicator of systemic atherosclerosis and is linked to increased risks of heart attacks and strokes. Low ABI values can identify patients at higher cardiovascular risk.
Monitoring PAD Progression
Physicians use ABI for follow-up assessments in PAD patients to monitor the progression of the disease or the effectiveness of treatments, such as medication or revascularization procedures.
Pre-surgical Evaluation
ABI testing is used preoperatively to assess the vascular status of patients undergoing lower extremity surgeries or interventions, ensuring that sufficient blood flow is present.
Toe-Brachial Index (TBI) Applications
Smart-ABI+
PAD Diagnosis in Diabetics and Elderly
In cases where arterial calcification in the lower limbs (common in diabetic and elderly patients) may result in falsely elevated ABI readings, TBI is preferred for more accurate detection of PAD. The smaller arteries in the toes are less likely to be calcified.
Assessment of Small Vessel Disease
TBI is useful for evaluating small vessel disease in patients with conditions like diabetes, where the ABI might not reflect the true extent of vascular compromise.
Wound Healing Prognosis
TBI can help in predicting the likelihood of wound healing in the lower extremities, especially in patients with foot ulcers or after amputations.
Follow-up for PAD Patients with Calcified Arteries
For patients whose arteries are non-compressible due to calcification, TBI offers a reliable alternative for assessing blood flow in the lower extremities.
Cuff-based measurement, VPR waveforms, documented accuracy.
A true ABI test uses inflatable cuffs to measure segmental pressures, not a photoplethysmography (PPG) light signal alone. That distinction matters for both clinical accuracy and the way vascular-study claims are reviewed.

We install, we train, we stay.
What happens between the order and your first patient test.
On-site installation
A Smart-ABI representative installs Smart-ABI or Smart-ABI+ in your practice and integrates it into your workflow, rather than shipping a box.
Staff training
Your medical assistants are trained on the Smart-ABI Process, a decision-tree workflow that starts at the front desk, so an MA can run the test before the physician enters the room.
Smart-ABI Hub setup
Hub access is set up so signed, color-coded reports are ready to add to your EMR.
Ongoing support
Technical support and customer service continue after installation. The Extended Service Agreement adds Hub access, unlimited support, and the extended software warranty.
What Smart-ABI practices say.
Two of the 40+ five-star Google reviews. Quotes are lightly trimmed for length.
“Very easy and fast device to use, very user friendly. Moving from a manual ABI machine to this automatic Smart ABI was the best move for OCV.”
“I’ve been using Smart ABI for 2 years. It works great and is easy for my MAs to run. My patients appreciate not having to be sent out for an ABI and I enjoy the revenue.”
