Wavelet analysis-based respiration abnormity monitoring method

Abstract

The invention relates to the technical field of respiration monitoring, and discloses a wavelet analysis-based respiration abnormity monitoring method, which comprises the following steps of: designing a humidity sensor, and monitoring a respiration waveform signal of a user by utilizing the humidity sensor; fitting the breathing waveform signal by using a fitting method based on an interpolation function, and determining a frequency band boundary of the breathing waveform signal; designing a wavelet filter according to the determined frequency band boundary, and performing adaptive decomposition processing on the respiratory waveform signal by using the wavelet filter to obtain an adaptive decomposition signal; performing noise reduction processing on the self-adaptive decomposition signal by using a wavelet threshold function to obtain a noise reduction signal; and using a random forest model to perform respiratory anomaly identification monitoring on the denoised respiratory signal. The invention further provides a wavelet analysis-based respiration abnormity monitoring method. According to the invention, abnormal breathing monitoring is realized.

Description

technical field [0001] The present invention relates to the technical field of breathing monitoring, in particular to a method and system for monitoring abnormal breathing based on wavelet analysis. Background technique [0002] With the continuous advancement of science and technology, people pay more and more attention to their own health, how to monitor their health more conveniently has become an urgent problem to be solved. [0003] Respiratory monitoring method is a relatively common method to prevent the sudden onset of apnea syndrome. When a patient suffering from sleep apnea syndrome suffers from apnea during sleep, the respiratory monitoring system can detect this situation at the first time and issue an alarm. Alarm, thus winning precious time for the treatment of its sudden apnea. [0004] The traditional breathing monitoring method is to use a pressure sensor to monitor breathing. The principle of this method is that when the subject exhales air, the pressure m...

Problems solved by technology

[0004] The traditional breathing monitoring method is to use a pressure sensor to monitor breathing. The principle of this method is that when the subject exhales air, the pressure monitored by the sensor increases to monitor the patient's breathing. However, the patient must wear a heavy and inflexible mask and Uncomfortable nasal cannula, which can negatively affect the patient's breathing
