Abstract

The invention relates to a man-machine asynchronous mechanical ventilation detection method based on a circulating neural network. The method comprises the following steps: a, collecting respiratory records during mechanical ventilation, and marking types of man-machine asynchrony by an expert; b, training and testing a multi-channel circulating neural network model on the basis of the marked respiratory records; c, detecting occurrence of various types of man-machine asynchrony by multi-model integration architecture. Characteristics of respiratory recording pressure waveforms and flow waveforms are fully extracted by adopting the multi-channel model structure, and after the characteristics are fused, the circulating neural network model is used for detecting occurrence of man-machine asynchrony. The occurrence of various types of man-machine asynchrony in the respiratory records can be simultaneously detected.

Description

technical field [0001] The invention relates to a cyclic neural network technology, in particular to a detection method, which is based on a cyclic neural network model to detect man-machine asynchrony during mechanical ventilation. Background technique [0002] Mechanical ventilation refers to the use of a ventilator to replace or assist the work of the respiratory muscles when the respiratory organs cannot maintain normal gas exchange, that is, when respiratory failure occurs. Mechanical ventilation strives for treatment time and creates conditions for clinical respiratory failure caused by various reasons, as well as other diseases that require respiratory function support. [0003] Today, with the popularity of ventilators, many clinicians only focus on their basic functions such as relieving respiratory muscle fatigue, improving ventilation and oxygenation. Although the patient's vital signs are maintained and blood gas indicators are improved, the patient's subjective...
