Abstract

A system and method are provided to detect a possible respiratory blockage by using personalized carbon dioxide (CO₂) concentration change patterns. The personalized change patterns can intelligently learn new change pattern to increase its accuracy. Advanced pattern recognition is used to detect abnormal CO₂ concentration change pattern by comparing to personalized patterns, and allowing the system to trigger alarm to alert a caregiver or a guardian.

Claims

1. A method for detecting respiratory blockage, comprising:

detecting diffused carbon dioxide (CO₂) concentration level by a biosensor from a person'"'"'s skin while said person is engaging in an activity;

analyzing changes of said CO₂ concentration level;

generating a first CO₂ change pattern based on said analyzed changes of said CO₂ concentration level;

recording said CO₂ change pattern of said person as a first personalized pattern in a database;

comparing said first recorded personalized pattern to a newly generated CO₂ change pattern by detecting diffused CO₂ from said person; and

,

adding said newly generated CO₂ change pattern as a second personalized pattern to said database if the first CO₂ change patter is substantially different from said newly generated CO₂ change pattern.

2. The method of claim 1, wherein said activity is a quiet activity or a mild activity or a vigorous activity.

3. The method of claim 1, wherein said comparison triggers an alarm when the first CO₂ change patter is substantially different from said newly generated CO₂ change pattern.

4. The method of claim 1, wherein said adding is determined by said person.

5. The method of claim 1, further comprising adding a pre-recorded CO₂ change pattern of heart rate change to said database.
