Abstract: A monitoring system is provided. The monitoring system includes a controller and either a shunt device, an externally-communicating catheter, and/or a fluid retention device. The shunt device and catheter are configured to address fluid movement such as ascites and pleural effusions. Each of the shunt device and catheter include a plurality of sensors that communicate with the controller positioned external to a body of a subject. The plurality of sensors are configured to output a signal indicative of a total volume, a glucose amount, or an oxygenation within a fluid flowing in contact within or surrounding the shunt device or the catheter.
