      Article
      Accés obert
      We measured transthoracic impedance in nine presumed healthy adult subjects with a two-frequency plethysmograph at 57 kHz and 185 kHz. The measurement protocol included periods of normal breathing without motion and periods ...

      Text en actes de congrés
      Accés restringit per política de l'editorial
      Non-invasive evaluation of respiratory activity is an area of increasing research interest, resulting in the appearance of new monitoring techniques, ones of these being based on the analysis of the diaphragm mechanomyographic ...
    • Signal-to-motion artifact ratio versus frequency for impedance pneumography 

      Rosell Ferrer, Francisco Javier; Webster, John G. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1995-03-01)
      Article
      Accés obert
      We measured transthoracic impedance between 12.5 and 185 kHz in nine adults. We used a system with two impedance channels, both simultaneously detecting the real part of impedance at two different frequencies. We used only ...
