Identification method and system based on integrated tree for false positive alarm signals in ventilator

Abstract

The invention discloses an identification method and a system based on an integrated tree for false positive alarm signals in a ventilator. The identification method comprises the following steps: S1,data collection: collecting monitoring data of a patient from a ventilator and a monitor in a hospital; S2, data preprocessing: processing missing values and abnormal values in a dataset, conductingstandardization, and generating rules for identifying false positive alarm signals; S3, feature extraction: sorting features by using a random forest, and selecting the features with good recognitioncapability; and S4, false positive alarm signal identification: establishing a false positive alarm signal identification method for the ventilator and the monitor. Experimental results show that themethod of the present invention has excellent identification performance for false positive alarm signals and robust identification effect.

Description

technical field [0001] The invention relates to a method and system for identifying a false positive alarm signal of a hospital ventilator-monitor, in particular to a method and system for identifying a false positive alarm signal of a ventilator based on an integrated tree. Background technique [0002] As a kind of first aid and life support medical equipment, ventilator has been widely used in modern clinical medicine, such as for the treatment of respiratory failure caused by various reasons, anesthesia breathing management during major surgery, respiratory support treatment and emergency resuscitation Waiting for the patient. Since ventilators are mainly used for patients with high-risk conditions, they are usually used together with monitors. When the patient's breathing is abnormal or the equipment fails, the ventilator-monitor will send out an alarm signal, and the medical staff will check the status of the corresponding patient and check the operation of the equipm...

Problems solved by technology

[0006] The technical solution of the present invention is to provide a method and system for identifying false-positive alarm signals of ventilators based on an integrated tree, so as to make up for the current problem of subjective judgment or poor recognition effect in the identification of false-positive alarm signals of ventilator-monitors, and Solve the problems of high pressure on medical staff and missing the best treatment opportunity caused by false positive alarms
