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.

A method for monitoring blood oxygen saturation level of a user, the method to be implemented by a monitoring device communicating with a blood oxygen saturation detector, the blood oxygen saturation detector being worn by the user to periodically measure the blood oxygen saturation level of the user, the method comprising steps of:
- obtaining a plurality of values of blood oxygen saturation level from the blood oxygen saturation detector, the values of blood oxygen saturation level being detected during a time period of a predetermined duration;
- obtaining an nth degree polynomial equation in two variables that represents a curve which fits the values of blood oxygen saturation level, where n is an integer equal to or greater than one;
- 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, wherein the step of outputting a warning includes:
- determining whether a last one of the values of blood oxygen saturation level is smaller than an abnormal value that represents severe low level of blood oxygen saturation;
- outputting a first warning notification to serve as the warning when it is determined that the last one of the values of blood oxygen saturation level is smaller than the abnormal value, wherein outputting the first warning notification includes outputting, by the monitoring device, the first warning notification to instruct the user to contact a medical professional, and transmitting the first warning notification to a care end device to instruct a caregiver associated with the care end device to check on the user;
- and
- outputting a second warning notification to serve as the warning when it is determined that the last one of the values of blood oxygen saturation level is not smaller than the abnormal value, wherein outputting the second warning notification includes outputting, by the monitoring device, the second warning notification to instruct the user to pay attention to subsequent variation in the blood oxygen saturation level;
- generating a control command that causes implementation of an intervening action.
