Abstract
A biological information monitoring system () configured to monitor biological information of a subject (S) on a bed (BD) includes at least one load detector () provided below the bed or legs of the bed and configured to detect a load of the subject on the bed, a waveform calculation unit () configured to calculate a waveform indicating a temporal variation in a detected value of the at least one load detector in accordance with respiration or a heartbeat of the subject, and a biological information calculation unit () configured to calculate a respiration rate or a heart rate of the subject by using the waveform. The biological information calculation unit includes a first calculation unit () configured to calculate the respiration rate or the heart rate of the subject by a first means based on the waveform, a second calculation unit () configured to calculate the respiration rate or the heart rate of the subject by a second means that differs from the first means and includes normalizing the waveform, and a calculation control unit () configured to cause the second calculation unit to calculate the respiration rate or the heart rate when an amplitude of the waveform is a threshold value or less.
