1. A system adapted to be worn entirely on a patient's body comprising:
an optical system adapted to be worn on a location of the body comprising an optical circuit connected to an optical sensor comprising a light source and an optical detector, the optical circuit configured to generate a waveform;
an impedance system adapted to be worn on the patient's body and connected to a first electrode that injects electrical current into the patient, and a second electrode that senses an impedance signal from the patient that results from the injected current; and
a digital processing system adapted to be worn on the patient's body and adapted to attach to the body by the first and second electrodes, the digital processing system comprising a microprocessor configured to receive the waveform, or a processed version thereof, and configured to process the waveform, or a processed version thereof, to generate a second physiological parameter, and further configured to receive the impedance signal and process it, or processed versions thereof, to generate an impedance-related parameter.
