The invention discloses a parametrization monitoring device and a monitoring method in a cardiopulmonary resuscitation process. The device comprises a motion tracker and a pressing detection module. In the process of implementing cardiopulmonary resuscitation, the motion tracker is worn on the wrist of a pressed hand of medical personnel, and the pressing detection module clings to the back of thepressed hand, so that pressing action information of the medical personnel can be acquired by the motion tracker in real time in the first-aid process, and meanwhile, data can be saved. The acquireddata is processed by a microprocessor, so that data of a single-time pressing amplitude, effective pressing times, pressing time and the like can be obtained and the data can be stored in a data storage module of the motion track; and action standardization of the medical personnel can be reminded in forms of vibrating and prompt sound, so that the effectiveness and standardization of first-aid actions can be guaranteed. Moreover, by connecting a computer to a communication port of the motion tracking module, the data in the data storage module can be read, so that a success rate of the cardiopulmonary resuscitation can be improved, and in addition, monitoring data in the cardiopulmonary resuscitation process can be recovered, so as to analyze the rescue process to conveniently standardizea first-aid level and an action standard.
