Publication number: 20220122444Abstract: Disclosed are a monitoring apparatus and a method for operating same, a monitor and a computer storage medium. During the process of monitoring a monitored object, a monitoring signal of the monitored object is acquired in real time by a sensor accessory connected to the monitored object; monitoring parameter of the monitored object is obtained according to the monitoring signal, and the monitoring parameter is analyzed according to a first data analysis function. When the monitoring parameter satisfies a preset condition, a second data analysis function for at least one type of physiological parameter of the monitored object is turned on or off. Thus, a monitoring function for a physiological parameter of a monitored object can be turned on or off according to the current monitoring parameter of the monitored object, such that a monitored physiological parameter can be adaptively adjusted, thereby improving the monitoring quality.Type: ApplicationFiled: December 25, 2021Publication date: April 21, 2022Applicant: SHENZHEN MINDRAY BIO-MEDICAL ELECTRONICS CO., LTD.Inventors: Zehui SUN, Wenyu YE, Zehong GUAN, Sanchao LIU, Jian DAI, Xianliang HE
