Abstract
An abnormal respiration detection apparatus includes a sensor for sensing a PPG signal from an optical signal reflected and received from a user's body; a band pass filter for extracting a signal of a required band from the PPG signal; an analog-to-digital converter for performing a digital conversion on the filtered PPG signal; and an abnormal respiration recognition unit deriving a respiration rate signal from the digital-converted PPG signal, deriving a plurality of respiration rate characteristic values through a time axis analysis on the derived respiration rate signal, and detecting an abnormal respiration using the derived plurality of respiration rate characteristic values. The embodiments can be utilized to monitor the survival of elders who live alone, soldiers isolated in a military operation, persons isolated in disaster and accident sites, thereby contributing to public and social safety and building of welfare society and nation.
