SysToe measures toe pressure as part of the diagnosis or monitoring of peripheral arterial disease in the lower limbs. SysToe represents an ingenious application of infrared photoplethysmography (PPG) coupled to a unique algorithm, developed and patented by Atys medical. By means of a photoelectric cell, PPG detects changes in blood volume in skin. SysToe, by virtue of its reliability, ease of use and affordable price, enables toe systolic pressure measurement to be conveniently and readily performed by all health professionals (angiologists, nephrologists, diabetologists, vascular specialists, wound care centers, …). SysToe measures also finger systolic pressure for assessment of arteriovenous (AV) graft or fistula. Ease of use The user installs the occlusion cuff on the proximal phalanx of the toe or finger. He/she positions the sensor with its cuff on the distal phalanx. He/she presses the START key. Finally, he/she validates the toe blood pressure displayed on the SysToe. The measurement of toe systolic blood pressure with SysToe is easily achievable even outside the vascular laboratory. Comfort in use The cuffs are inflated and deflated automatically by the device and not by the user. The same cuffs can be used for the toes and fingers. Precision and sensitivity SysToe is able to measure blood pressures below 20 mmHg. The occlusion cuff is deflated automatically at a controlled rate that ensures good measurement accuracy. Clinical tests on 200 patients performed at the Nimes University hospital have demonstrated the reliability of the SysToe compared to laser Doppler.
