The SweatC Model A001 is a galvanic skin response technology related to the sweat gland function. It uses the sympathetic skin response (SSR) method to assess the sudomotor function via foot skin disposable electrodes following a predetermined electrical stimulations and specific sequence of measurement. The SweatC measures the absorption of the induced sweat on the bulk of the cloth electrodes. As perspiration increases, more sweat glands are stimulated which increases the voltage amplitude in a given area of skin covered by the disposable cloth electrodes. The test is performed in the supine position on an exam table and the patient needs to be relaxed at least 5 minutes.
Per the last published clinical study performed at the University of Miami: The SweatC marker NO Sweat Peak had a sensitivity of 88% and a specificity of 68% (Area Under the Curve = 0.81,p< 0.0001) to detect retinopathy. The NO Sweat Peak response marker inversely correlated with BUN (ρ=−0.41,p< 0.0001), homocysteine(ρ=−0.44,p< 0.0001), fibrinogen (ρ=−0.41,p< 0.0001), the Cardiac Autonomic Neuropathy score (ρ=−0.68,p<0.0001), and the heart rate variability Total Power (ρ=−0.57,p< 0.0001), and it positively correlated with the Photoplethysmography Index (PTGi;ρ=0.53p< 0.0001). The SweatC marker Sweat Peak inversely correlated with the severity of symptoms on the peripheral neuropathy scale (ρ=−0.56,p< 0.0001).


INTENDED USE 1. To spot check or monitor Oxygen saturation of arterial hemoglobin (SpO2%) and pulse rate. 2. To analyze the pulse waveform (Photoplethysmography or PTG) provided by the oximeter. It only provides mathematical analysis of the input of the PTG using the first and second derivatives of the PTG values related to the microvascular condition. 3. To analyze the basic rhythms of the NN or RR intervals in heart rate from the PTG, both in the time domain and in the frequency domain (short time 5 minutes). It only provides mathematical analysis of the heart rate variability values related to the autonomic nervous system function. PTG uses transmitted infrared and red light to measure oxygen saturation and relative blood volume in the fingertip. PTG waveform are reflective of blood movement in cutaneous vessels and can be used to identify synchronous depolarization of cardiovascular tissue.​
- Photoplethysmography (PTG) analysis to assess the peripheral circulation.
- HRV (Heart Rate Variability) analysis both in the time domain and frequency domain to assess early ANS dysfunction
- Ewing Tests analysis (Valsalva maneuver, deep breathing and K30/15 tests) to assess cardiovagal failure, orthostatic intolerance, Vagal syndrome and Postural Orthostatic Tachycardia Syndrome (POTS).


The TBL-ABI system is indicated for use on adult subjects at risk of having or developing peripheral arterial disease (PAD). TBL-ABI system is intended for the rapid measurement of ankle-brachial pressure index (ABPI), or ankle-brachial index (ABI), and pulse volume recording (PVR)/ volume plethysmography in adults. It is suitable for use in wound care assessment, for assessing symptomatic PAD, and as a screening device for PAD. It may also be used on patients with venous or arterial ulcers prior to the application of compression therapy. The ankle-brachial index (ABI) is the ratio of the systolic blood pressure measured at the ankle to that measured at the brachial artery.
