1. A system for measuring physiological signals from a patient, comprising:

  • a continuous, flexible, loop-shaped member configured to drape around the patient'"'"'s neck;

    an impedance-measuring system integrated within the loop-shaped member, the impedance-measuring system configured to receive a first set of electrical signals from near the patient'"'"'s neck and process them to determine an impedance signal;

    an ECG-measuring system integrated within the loop-shaped member, the ECG-measuring system configured to receive a second set of electrical signals from near the patient'"'"'s neck and process them to determine an ECG signal;

    a motion-measuring system integrated within the loop-shaped member, the motion-measuring system configured to generate a set of motion signals in response to the patient'"'"'s movements;

    a data-processing system integrated within the loop-shaped member and in electrical contact with the impedance-measuring system, the ECG-measuring system, and the motion-measuring system, the data-processing system operating a set of computer algorithms configured to process the impedance signal, the ECG signal, and the motion signal;

    a wireless transmitter integrated within the loop-shaped member and in electrical contact with the data-processing system, the wireless transmitter configured to transmit processed values of the impedance signal, the ECG signal, and the motion signal; and

    a battery system in electrical contact with and configured to power the impedance-measuring system, the ECG-measuring system, the motion-measuring system, the data-processing system, and the wireless transmitter.
