Abstract: A apparatus for detecting a biological data of a target patient from an attachable sensor attached to the target patient includes a circuit and a storage that stores therein a first correspondence relationship between a state of a battery included in the sensor and a measurement error of the sensor. The circuit obtains the biological data and battery data indicating the state of the battery, the obtained biological data and the obtained battery data being collected by the sensor, and generates corrected biological data by correcting the biological data according to the battery data, wherein the generating of the corrected biological data includes generating correction data that depends on the battery data by referring to the storage that stores the first correspondence relationship, and generating the corrected biological data by correcting the biological data using the correction data.

Abstract: An apparatus for detecting a biological data of a target patient from an attachable sensor attached to the target patient includes a circuit. The circuit obtains a first piece of biological data of the target patient and second piece of biological data of the target patient that is a different type of biological data than the first piece of biological data. The first piece of biological data and the second piece of biological data is collected by the sensor. The circuit standardizes the first piece of biological data on the basis of the second piece of biological data so as to generate standardized biological data.

Abstract: An apparatus for detecting a biological data of a target patient from an attachable sensor attached to the target patient includes a circuit. The circuit obtains a first piece of biological data and patient-state data of the target patient. The circuit determine an activity state of the target patient on the basis of the patient-state data. When the activity state is first state, the circuit detects an abnormality in the target patient on the basis of a first normal value range, in the first state, of a physiological indicator indicated by the first piece of biological data and the first piece of biological data. When the activity state is second state, the circuit detects an abnormality on the basis of a second normal value range, in the second state, of the physiological indicator indicated by the first piece of biological data and the first piece of biological data.
