  • TWO-ELECTRODE, IMPEDANCE-BASED RESPIRATION DETERMINATION
    Publication number: 20140343448
    Abstract: Methods, apparatuses and systems are described for determining respiration through impedance measurements using only two electrodes. A drive signal may be applied to a person, using only two electrodes. Using the same electrodes, the fluctuations in the voltage of the drive signal are determined. The voltage fluctuations in the drive signal are the result of impedance variations in the person's thoracic cavity due to respiration. Therefore, the voltage fluctuations may be used to determine a respiration rate of the person. In doing so, the voltage fluctuations may be digitized using a sampling rate that is much less than the frequency of the applied drive signal.
