Minute ventilation sensor with dynamically adjusted excitation current |
摘要 |
A minute ventilation sensing device in which transthoracic impedance is measured with a excitation current waveform at a specified amplitude and frequency. In order reduce interference with the impedance measurement from external noise sources, a noise detection operation may be performed with the amplitude and/or frequency of the excitation current waveform adjusted accordingly.
