Data can be forwarded to a data center of a server through Bluetooth, wired communication way or ZIGBEE short-distance wireless communication based on user selection. In order to solve the defects in the prior art, the invention provides a method and a system for measuring oxygen saturation and heart rate, wherein the system has high measurement efficiency, is convenient in use and can be operated remotely.

Description

technical field [0001] The invention relates to a method and system for measuring blood oxygen saturation and heart rate. Background technique [0002] Under the prior art, blood oxygen saturation measurement methods and measurement systems have the following disadvantages: [0003] 1. The traditional blood oxygen saturation measurement method is to collect blood from the human body, and then use a blood gas analyzer for electrochemical analysis to measure the oxygen partial pressure and calculate the blood oxygen saturation. This method is not only troublesome, but also cannot carry out continuous monitoring. [0004] 2. Ordinary non-invasive pulse oximeters are expensive and complicated and can only be operated by professional medical staff. [0005] 3. The accuracy of commercially available portable pulse oximeters is relatively poor, especially the interference shielding ability to motion artifact noise is poor. It cannot realize remote data transmission, remote medic...
