Minimally invasive lung bioimpedance measurements could serve in the future diagnosis of lung pathologies complementing biopsies and imaging techniques. Through the electrical impedance spectroscopy (EIS) technique using the 3-electrode method, distinction of lung pathologies could be possible depending on the state of the tissue. Since now, only averaged information has been used for the analysis of bioimpedance data in lungs. The aim of this study is to use temporal information to evaluate changes in the impedance signal due to the mechanism of ventilation and perfusion produced by the lungs. Preliminary results show: 1) correlation between ventilation and perfusion with the bioimpedance signal and 2) changes in the amplitude of the bioimpedance time signal depending on the pathology. As conclusion, together with cycled averaged data, temporal data could be useful for lung pathologies distinction. [ABSTRACT FROM AUTHOR] |
