About the TM Flow System

TM Flow System focuses on early detection and follow-up of complications (autonomic nervous system & vascular system) of chronic metabolic diseases such as diabetes.

The TM FLOW System includes the following tests to determine these clinical outcomes and includes:
  • Sudomotor function tests – using sympathetic skin response
  • Photo-plethysmography analysis – using an oximeter. This includes heart rate variability analysis and spectral analysis of the oximeter waveform.
  • Cardiac Autonomic Reflex Tests or EWING Tests: which include valsalva maneuver, deep breathing exercises, postural changes
  • Ankle Brachial Index (ABI ) measurement using PPG
