Semi-automated Vascular Doppler Recorder for ABI/TBI

Semi-automated Vascular Doppler Recorder for ABI/TBI

Product Code: VASOCHEK+

The Ankle Brachial Index (ABI) is a measure of the severity of atherosclerosis in the legs but is also an independent indicator of the risk of subsequent atherothrombotic events elsewhere in the vascular system. The ABI may be used as a risk marker both in the general population free of clinical CVD and in patients with established CVD.

Continuous wave Doppler ultrasound is considered a reliable tool and was validated and accepted into routine medical practice. The literature recognises the importance of assessment in the management of a patient with chronic lower limb ulceration. The evidence from the medical literature indicates that a "normal" ABI is 0.91 or greater, a ratio below this indicating arterial disease.

Patients with DM may have calcified and hardened lower extremity arterial walls that cannot be readily compressed and occluded with blood pressure cuffs. This produces falsely elevated ankle pressure readings that are often in the "normal ABI range" (0.91 to 1.4) or sometimes in the non-physiological range of above 1.4. However, Calcified leg arteries in Diabetes Mellitus or dialysis patients may yield falsely elevated ABI results.

A photoplethysmogram (PPG) is an optically obtained Plethysmogram, a volumetric measurement of an organ. The PPG Toe blood pressure and related Toe Brachial Index (TBI) are performed to assess the vascular condition of the foot by obtaining systolic pressures at the toe. Toe pressures may be useful in cases of unsuspected vascular disease and in baseline diabetic foot assessment where falsely high ankle pressures can occur due to calcification of tibial vessel.

Vasochek+ is a complete non-invasive unidirectional semi-automated vascular doppler recorder designed to measure the ABI, TBI and the velocity waveform. Computer connectivity using USB port helps the device connected to a Windows 7/8/10 operated computer. The software supplied helps to capture the Doppler waveforms for storage and patient report generation. The software interprets the result as per TASC II guidelines.
