Claim 19:
20. A system for measuring fluids from a patient, comprising:
a C-shaped wrist-receiving portion including a first pair of electrodes configured to be disposed on the patient's wrist, with a first electrode in the first pair of electrodes configured to inject electrical current into the patient's wrist to induce a first bio-electric signal in the patient, and a second electrode in the first pair of electrodes configured to sense the first bio-electric signal from the patient;
a hand-grip portion including an optical sensor;
a body-contacting portion, disposed along a bottom of the C-shaped wrist-receiving portion, the body-contacting portion including a second pair of electrodes configured to be disposed on the patient's body, with a first electrode in the second pair of electrodes configured to inject electrical current into the patient's body to induce a second bio-electric signal, and a second electrode in the second pair of electrodes configured to sense the second bio-electric signal from the patient;
an impedance-measuring system, configured to be disposed on the patient's wrist, configured to connect to the first and second pairs of electrodes to receive the first and second bio-electric signals and process the first and second bio-electric signals to determine an impedance plethysmogram; and
a processor, configured to be disposed on the patient's wrist, configured to process the impedance plethysmogram to measure a value corresponding to fluids in the patient.
