Assessment of lower limb arterial diseases
Ankle systolic blood pressure measurement is an essential step of the evaluation and monitoring of lower limb arterial diseases.
This measurement based on sphygmomanometry and ultrasound Doppler remains difficult and may be impossible or unreliable in patients with diabetes, patients with chronic renal failure and eldery patients because their peripheral artieries become incompressible as a result of medial calcinosis. In this case, the systolic pressure measurement remains feasible at the hallux where the incidence and extent of arterial wall calicification are much lower.
New prospects for non invasive measurement of toe pressure
Currently available systems for the measurement of systolic blood pressure (standard PPGm laser Doppler, mercury strain gauge, ultrasound Doppler) suffer from significant drawbacks as for ergonomics, reliability or price, which have so far limited their clinical use.
Optimised for cost, reliability, accuracy and easiness of use, Systoe enables toe pressure measurement to be conveniently and readily performed by all health professionals.
SysToe offers major improvements
The measurement is operator independent
SysToe is fully automated, including cuff inflation, deflation and data value display.
Once the cuff and the sensor are placed on the toe, just press on the START key to start the measurement and get the display of the toe pressure value.
The measurement is fast
The value of the toe pressure is displayed within three minutes.
The measurement is reliable, accurate and reproducible
The measurement is highly sensitive
SysToe is able to measure pressures lower than 20mmHg.
SysToe displays the toe systolic pressure and the Toe Brachial Index (TBI)
Operating method
SysToe cleverly employs photoplethysmography (PPG) analysed by a unique patented algorithm designed by Ayts Medical.
Light from an emitting diode (LED) is directed towards the skin where it is absorbed and scattered in tissues. An adjacent photosensor detects the backscattered light thats variations are related to changes of blood volume in underlying tisues.
The PPG senosr is placed on the distal pad of the toe and the occlusion cuff is wrapped on the proximal part of the toe.
The occlusion cuff is inflated automatically to a pressure sufficient to stop blood flow, then deflate slowly as a controlled rate. During deflation, resumption of blood flow downstream from the cuff is detected by the PPG senosr.
The cuff pressure at this time id the toe systolic pressure.
The measurement curves and results are stored in the SysToe internal memory for later transfer to a PC, printout and archiving.
