Abstract
Provided is an exacerbation prediction device equipped with a respiration sensing means of continuously sensing respiration data of a patient, a calculation means of calculating stable respiration data that are respiration data during a condition in which a respiratory rate is lowered and stable for a certain period of time from the sensed continuous respiration data of the patient, and a prediction means of predicting occurrence of an acute exacerbation in the patient in accordance with the stable respiration data calculated during a certain period of time.
Claims7
An exacerbation prediction device comprising:
- a respiration sensor configured to continuously sense respiration data of a patient;
- and
- a processor configured to:
- calculate stable respiration data, based on respiration data that are sensed during a sleep of the patient, by determining the stable respiration data as a portion of the respiration data that satisfies a condition in which a respiratory rate of the respiration data is lowered and stable for a certain period of time among the respiration data of the patient that is sensed during the sleep of the patient among the continuously sensed respiration data, and
- predict an occurrence of an acute exacerbation in the patient based on the stable respiration data calculated with respect to the certain period of time.
An oxygen concentration device comprising:
- a compressor configured to compress an air;
- an adsorption cylinder configured to receive the compressed air from the compressor, selectively adsorb nitrogen from the air, and output an oxygen-enriched gas;
- an oxygen supply path configured to supply the oxygen-enriched gas to a patient;
- a respiration sensor provided in the oxygen supply path and configured to continuously sense respiration data of the patient;
- and
- a processor configured to:
- calculate stable respiration data, based on respiration data that are sensed during a sleep of the patient, by determining the stable respiration data as a portion of the respiration data that satisfies a condition in which a respiratory rate of the respiration data is lowered and stable for a certain period of time among the respiration data of the patient that is sensed during the sleep of the patient among the continuously sensed respiration data, and
- predict occurrence of an acute exacerbation in the patient based on the stable respiration data calculated with respect to the certain period of time.
An exacerbation prediction device comprising:
- a patient-side terminal having a respiration sensor configured to continuously sense respiration data of a patient, and an output terminal configured to transmit the continuously sensed respiration data of the patient to an outside, and
- an external terminal having a processor configured to:
- receive the continuously sensed respiration data of the patient,
- calculate stable respiration data based on respiration data that are sensed during a sleep of the patient, by determining the stable respiration data as a portion of the respiration data that satisfies a condition in which a respiratory rate of the respiration data is lowered and stable for a certain period of time among the respiration data of the patient that is sensed during the sleep of the patient among the continuously sensed respiration data, and
- predict an occurrence of an acute exacerbation in the patient based on the stable respiration data calculated with respect to the certain period of time.
