A biological state monitoring system () for monitoring a biological state of a subject on a bed (BD) over a predetermined monitoring period, includes: at least one load detector () configured to detect a load of the subject on the bed; and a respiratory rate estimating unit () configured to successively obtain and output estimated values of a respiratory rate of the subject, based on a temporal variation of a detection value of the load detector. The monitoring period includes a body motion period in which the subject has a body motion, and a resting period in which the subject merely performs a respiration. In a case that the monitoring period shifts from a first resting period to the body motion period and then from the body motion period to a second resting period, the respiratory rate estimating unit outputs, in the body motion period and a predetermined period starting from the shifting from the body motion period to the second resting period, a last estimated value which is the latest among the estimated values obtained successively in the first resting period.

Biological state monitoring system

There is provided a biological state monitoring system for monitoring biological state of subject on a bed. The system includes at least one load detector and a controller. In a case that the controller determines that body motion is not twitch, the controller ceases to output estimated value of respiratory rate, or outputs first estimated value which is the latest among estimated values obtained in first period, the first period being directly preceding body motion and being determined by the controller to be a period in which subject has no body motion. In a case that the controller determines that body motion is twitch, the controller successively outputs newly obtained estimated values of respiratory rate.
