1. A medical device, comprising:
- a measuring interface, located between a device and a measuring site of a patient;
one or more electrodes to generate a frequency sweep stimulation signal, positioned at the measuring interface and in electrical contact with a portion of the patient;
circuitry to measure total bioimpedance values as a result of the stimulation signal at specific frequencies correlating to the frequency sweep; and
a processor system to a quantify a fluid contribution, an ion contribution, and a fat contribution from the measured total bioimpedance values from which a physiological report can be generated, wherein the processor system further identifies whether a measured total bioimpendance is reliable based a non-fluid contribution.

Abstract
Embodiments relate to a device and a method of monitoring and analyzing physiological parameters of a patient. The method includes electrically connecting one or more electrodes with a measurement site of a patient, generating a stimulation signal or signals sufficient to provide multiple stimulation frequencies, multiple waveforms or a combination thereof, measuring a one or more bioimpedance values from the generated signals and analyzing at least one of a fluid bioimpedance contribution, fat bioimpedance contribution or ion bioimpedance contribution within the one or more bioimpedance values sufficient to generate a physiological report.
