Abstract: A physiological information acquisition device includes: a reception interface configured to receive waveform data corresponding to a measured waveform of a physiological parameter of a subject from a sensor; a notifier configured to output an alarm indicating that the physiological parameter is not normally acquired; a processor configured to cause the notifier to output the alarm based on the waveform data; and a predictor configured to predict, based on the waveform data, a probability that the physiological parameter is erroneously calculated. The processor is configured to cause the notifier to perform a notification of at least one of a quality of the waveform data, a state of the sensor, and an action shall be taken by a user, based on the probability.

Abstract: A fluid balance management system includes: a detection device configured to output a detection signal corresponding to a load applied to a bed in which a subject is present; a prediction device configured to acquire load variation information indicating a variation over time of the load based on the detection signal, and predict an event that causes variation in fluid balance of the subject from the load variation information; and an output device configured to output prediction information corresponding to a prediction result of the event.

Abstract: A method for generating a learned model applied to a prediction device that predicts a probability that a subject develops delirium based on a moving image in which the subject appears is provided. The method includes: acquiring first data corresponding to the moving image in which the subject appears; generating, based on the first data, second data corresponding to changes over time in relative positions of a plurality of feature points in a body of the subject in the moving image; generating third data indicating a determination result as to whether the subject develops delirium based on the moving image; and generating the learned model by causing a neural network to learn using the second data and the third data.

Abstract: A processing device configured to process physiological information of a subject, the processing device includes a reception interface configured to receive first data corresponding to a measurement waveform of a first physiological parameter of the subject, and second data related to an acquisition environment of the first physiological parameter, an predictor configured to predict a first probability of correctly calculating a value of the first physiological parameter, based on the first data, and a processor configured to identify, of the first data, a part in which the first probability is higher than a first threshold under a circumstance where the first physiological parameter is determined to be abnormally acquired based on the second data.

Abstract: A method for generating a trained model is applied to an estimation apparatus configured to estimate a probability that a value of a predetermined physiological parameter is correctly calculated based on waveform data acquired from a subject being tested. The method includes: acquiring first data corresponding to a value of a first physiological parameter that has been correctly calculated from first waveform data; inputting second waveform data to an algorithm automatically calculating a value of a second physiological parameter acquired from input waveform data and to output second data; generating third data including a training label indicating whether the value of the second physiological parameter corresponding to the second data is a correct answer or an incorrect answer by comparing the second data with the first data; and training a neural network by using the second waveform data and the third data, to generate a trained model.

Abstract: A patient monitor (10) acquires a vital sign that is based on a physiological signal of a subject, and an ultrasonic image that is based on a reflected wave of an ultrasonic wave which is irradiated onto the subject. A display section (16) displays information of the subject. A control section (14) switches between a first mode in which a screen containing information of the vital sign is displayed on the display section (16), and a second mode in which a screen containing the ultrasonic image is displayed on the display section (16).
