Automated Dopplers Vascular ABI / TBI
Automated Vascular Doppler Recorder for ABI / TBI - Item Code: VERSALAB Auto
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 Vascular 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.
Pulse volume recording, also known as air Plethysmography, is a noninvasive test that measures blood flow within the blood vessels or arteries. The first sign of possible abnormality is the absence of the dicrotic notch. More significant occlusions will show a decreased slope of the ascending and descending segments and a rounding of the systolic peak. More serious obstructions will show flattened waveforms.
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.
VERSALAB Auto is capable of conducting ABI, TBI, PVR, Segmental Doppler, Upper Extremity Exam, Carotid and Penile Doppler studies. The blood pressure for the above measurements are done by a built-in mechanism and the BP measurement are validated by the software and helps the user to correct the BP measurement incase of any patient artifact. This quality control method helps to detect the systolic BP accurately.
