It is noninvasive, harmless, cheap, simple to operate and informative. It also has advantages of accurate measured results and high measurement repeatability. Therefore, medical detection based on bioelectrical impedance technology is increasingly used in the research and clinical. Methods This paper describes the application of bioelectrical impedance detection method in biomedical aspects, i.e. electrical impedance respiration monitoring, impedance of blood flow, bioelectrical impedance body composition detection, bioelectrical impedance method to detect stomach dynamics, bioelectrical impedance method to assess human cardiopuhnonary resuscitation and electrical impedance tomography technology. Results Although there are many influencing factors using bioelectrical impedance measurement method, including electrodes system such as the electrode polarization and the body contact between the electrode impedance, the system of relatively fixed position system; And measurement time state influence on measurement results such as impact of exercise on bioelectrical impedance method, the influence of anthropometric when food intake, the body posture change when measurement. However, bioelectrical impedance analysis in biomedical measurements still occupies an important position. Conclusion Bioelectrical impedance method is the basic method for biomedical detection. This article reviews for us having the significance on measuring the human body physiological and pathological information by bioelectrical impedance measurement.
