Breathing state detection method and system based on abdomen and lung data correlation

Abstract

The invention discloses a breathing state detection method based on correlation of abdomen and lung data, and the method comprises the steps: collecting inlet and outlet gas volume data of a patient in a one-time stable breathing state through a mouth and nose sensor as lung breathing data, and carrying out the preprocessing; abdomen displacement data of the patient in different breathing states are collected through an abdomen sensor and preprocessed, and the breathing rate is calculated; performing time sequence alignment on the lung respiration data and the abdomen displacement data by adopting a dynamic time warping algorithm, and outputting an optimal alignment distance; forming a two-dimensional feature value by using the optimal alignment distance and the respiratory rate, and training an SVM classifier to classify the respiratory state; and performing breathing state classification on to-be-detected abdomen displacement data through the trained SVM classifier. The breathing state can be judged in real time only by collecting the abdomen data of the patient, the wearing device is simplified, and meanwhile the detection accuracy can be improved.

Description

technical field [0001] The invention belongs to the technical field of breath detection, and in particular relates to a breath state detection method and system based on the correlation between abdomen and lung data. Background technique [0002] Breathing is an important physiological indicator. Through the detection of breathing state, different physical states can be reflected. The scope of respiratory detection is extremely wide. For critically ill patients, it is necessary to check the breathing status at all times. In community and family work, it is necessary to check the breathing status all night for groups with sleep apnea symptoms. In view of this actual situation, a method that can detect the breathing status in real time and Devices appear to be very necessary, and real-time breath detection devices can alleviate the shortage of resources in the monitoring of hospitals and communities. Respiratory state detection mainly includes respiratory rate, respiratory am...
