一种基于能量谱非接触呼吸暂停检测技术的研究
Study on Technique for Non-contact Apnea Detection Based on Energy Spectrum
摘要
Abstract
Objective To study a new technique for non-contact detection of the occurrence of apnea from the respiratory signal monitored by the bio-radar. Methods According to the characteristics of strength from the normal respiratory signal and the apnea one, the energy spectrum based on time domain was proposed. Firstly, the apnea signal was constructed and processed to judge whether the apnea occurred based on the threshold. Then the respiratory signals collected by the bio-radar were processed according to the threshold to determine the occurrence of apnea. Results The method based on the energy spectrum could better determine the occurrence of apnea in the environment that the signal to noise ratio was greater than -8 dB. Conclusion The method proposed based on the energy spectrum can make realtime judgment of the occurrence of apnea from the respiratory signal detected by bio-radar关键词
