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

  • an impedance pneumography sensor connected to at least two electrodes, the impedance pneumography sensor comprising a processing circuit configured to process signals from the at least two electrodes to measure an impedance pneumography signal from the patient;

    a motion sensor connected to the patient and configured to measure at least one motion signal corresponding to motion of a portion of the patient'"'"'s body to which it is attached; and

    a processing system configured to receive the impedance pneumography signal and process it to determine a frequency-domain impedance pneumography spectrum, and to receive the motion signal and process it to determine a frequency-domain motion spectrum, the processing system further configured to collectively process both the impedance pneumography spectrum and motion spectrum to remove motion components from the impedance pneumography spectrum and then determine respiratory rate.
