With the development of sensor technology, information acquisition and processing technology, internet technology, portable, intelligent, networked, precise and modular monitoring equipment have gradually become the development trend of physiological parameters. By investigating the research results and market trends in the field of physiological parameter monitoring in recent years, this paper summarizes the research status of physiological parameter monitoring technology and monitoring equipment, analyses the problems and challenges it faces, points out its future development trend, and puts forward the prospect of future work. The purpose is to provide references for the study of physiological parameters monitoring and to pave the way for the further development of this field.
