/Method, Monitoring System And Monitoring System Device For Monitoring Blood Oxygen Saturation Of User, And Machine-readable Storage Medium
Abstract

A method for monitoring blood oxygen saturation level of a user includes: obtaining a plurality of values of blood oxygen saturation level measured during a predetermined time duration; obtaining an nth degree polynomial equation that fits the values of blood oxygen saturation level; determining whether a leading coefficient of the nth degree polynomial equation is smaller than a predetermined value that is associated with a normal variation in blood oxygen saturation level; and when it is determined that the leading coefficient is smaller than the predetermined value, outputting a warning indicating that the blood oxygen saturation level of the user is getting worse.
