Fatigue classification-based rest oxygen supply synergistic regulation method and device

Abstract

This invention discloses a method and device for coordinated regulation of rest-based oxygen supply based on fatigue grading, relating to the field of oxygen supply regulation technology. The method includes: S1, collecting fatigue-oxygen coordination data and performing preprocessing on the data; S2, dividing the respiratory phase window, generating an oxygen generation gating code sequence and an air supply gating code sequence, and generating a gated fatigue response kernel group through sliding inner product decoding and Wiener deconvolution processing; S3, calculating the blood oxygen uptake phase drift value, the heart rate bradycardia slope loss value, and the respiratory rhythm broadening value, and generating a fatigue grading result based on the periodic variation relationship of these three values; S4, constructing a grade constraint response matrix, solving for the execution adjustment vector, performing avoidance correction on the execution adjustment vector, and outputting the coordinated regulation result of rest-based oxygen supply. This solves the problem that existing rest-based oxygen supply equipment is difficult to combine fatigue grading and respiratory phase coordinated regulation to control oxygen supply and air delivery, resulting in delayed oxygen supply to the mouth and nose area and a lack of stable quantitative evidence for blood oxygen recovery.
