Information processing device, monitoring device, and non-transitory computer-readable medium

A monitoring device configured to monitor physiological information of a subject, comprising:

• an interface configured to receive a signal corresponding to a waveform of physiological information involving cyclic changes from a sensor attached to the subject;
• an output device;
• and
• a processor configured to cause, in response to the signal, the output device to output information corresponding to an estimated value of a respiration rate of the subject,
• wherein the processor is configured to:
• extract multiple feature quantities corresponding to respiration of the subject from the signal included in each of multiple time slots;
• apply frequency analysis processing with respect to each of the feature quantities to acquire multiple preliminary estimation values of the respiration rate;
• and
• determine the estimated value based on a mode value of the preliminary estimation values.

A non-transitory computer-readable medium having stored a computer program adapted to be executed by a processor installed in an information processing device configured to process physiological information of a subject, the computer program being configured to, when executed, cause the information processing device to:

• receive a signal corresponding to a waveform of physiological information involving cyclic changes from a sensor attached to the subject;
• extract multiple feature quantities corresponding to respiration of the subject from the signal included in each of multiple time slots;
• apply frequency analysis processing with respect to each of the feature quantities to acquire multiple preliminary estimation values of a respiration rate of the subject;
• determine an estimated value of the respiration rate based on a mode value of the preliminary estimation values;
• and
• cause an output device to output information corresponding to the estimated value.
