System for management and prevention of venous pooling

A monitoring system comprising:

• a plurality of sensors adapted to be worn by a user;
• a processor linked with the plurality of sensors, wherein the processor is adapted to receive sensor data and process said data to:
• determine user posture data including data indicative of vertical distance between level of the user's heart and ankle;
• determine user step count to estimate user calf muscle activity and to determine whether the user is static or active;
• determine a user state, wherein the possible user states comprise:
• a user static state, a user active state, a pressure-increasing state, and a pressure-decreasing state;
• and
• estimate real-time venous pressure based on the user state, the estimated calf muscle activity, user posture, and a predetermined value of chronic venous insufficiency;
• and
• a neuromuscular electrical stimulation device, wherein the neuromuscular electrical stimulation device is configured to be activated by the processor according to estimated real-time venous pressure.
