1. A system for monitoring respiratory rate from a patient, comprising:

  • a cable comprising;

    an impedance pneumography system comprising;

    i) a connecting portion configured to connect to a plurality of electrodes configured to be worn on the patient;

    ii) a differential amplifier configured to receive electrical signals from each of the plurality of electrodes and process them to generate an analog impedance pneumography signal; and

    iii) an analog-to-digital converter configured to convert the analog impedance pneumography signal into a digital impedance pneumography signal;

    an accelerometer system comprising;

    i) an accelerometer configured to generate an analog motion signal; and

    ii) analog-to-digital converter configured to convert the analog motion signal into a digital motion signal; and

    a processing system comprising a processor in electrical communication with the cable and configured to receive the digital data stream and collectively process the digital impedance pneumography and motion signals to determine the patient'"'"'s respiratory rate.
