Physiological measurements of cardiorespiratory activity with impedance pneumography

Abstract Impedance pneumography is a method of noninvasive, comfortable, and continuous respiratory activity measurement that allows recording quantitative parameters of respiratory rate, tidal volume, minute ventilation, or airflows. This chapter presents the comparison to spirometry and pneumotachometry; instrumentation, electrodes, and their configuration; and signal processing methods improving the accuracy of the results and signal's quality. It also discusses how to deal with motion artifacts, how to detect them, and how impedance pneumography may be used in cardiorespiratory applications with a multimodal signal acquisition. We described the causal framework as a domain for normative data analysis, athletes and astronauts profiling, and stress test characterization. The results supplemented all aspects. The limitations of the method, along with its other applications, were addressed.
