Abstract
This enables a simple and easy assessment of the reliability of respiratory rate, without requiring a complex system configuration. [Solution] A biological information measuring device is configured comprising: a respiratory rate calculation unit 7c that calculates the respiratory rate of a subject by deriving a respiratory waveform, which is a periodic virtual waveform, from a photoplethysmography waveform obtained from the subject; a reliability data generation unit 7d that calculates the variance of the period or the variance of the amplitude of the respiratory waveform derived by the respiratory rate calculation unit 7c, and generates reliability data that quantifies the reliability of the respiratory rate calculation result by the respiratory rate calculation unit 7c based on the calculated variance; and a display output unit 6 that displays and outputs the reliability data generated by the reliability data generation unit 7d.
