Embodiment Construction

[0056] In order to make the purpose, technical solution, implementation steps and advantages of the present invention clearer, the following content will further describe the present invention in detail in conjunction with the accompanying drawings and implementation examples. It should be noted that the specific implementation examples of this part are only used to explain the present invention, and are not used to limit the present invention, and the technical solutions formed by combining various parts in the implementation examples are within the protection scope of the present invention.

[0057] The present invention mainly aims at the problem that in the hospital environment, the ventilators and monitors supporting severe patients frequently generate false positive alarm signals, which in turn leads to a surge in the work pressure of medical staff. The present invention proposes a false positive alarm for ventilators based on an integrated tree The signal recognition met...

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...
