Single photoelectric sensor sleep breath multi-physiological parameter monitoring method and device

Abstract

The invention discloses a single photoelectric sensor sleep breath multi-physiological parameter monitoring method and device, and aims to obtain five physiological parameters on the basis of detection of a single photoelectric sensor. The single photoelectric sensor sleep breath multi-physiological parameter monitoring method comprises the following steps: 1, acquiring a pulse oximeter signal; 2, pretreating the acquired pulse oximeter signal; 3, judging whether a current measurement moment is in a moving state or not according to a detected peak point, a valley point and base line change information, if the current measurement moment is in the moving state, taking recognized non-movement state data as a normal pulse oximeter signal; 4, when detecting that the current measurement moment is in the moving state, performing body movement time counting; 5, according to the normal pulse oximeter signal, detecting pulse rate information, blood oxygen saturation degree information, breath information and pulse rate variability information; 6, according to the pulse rate, the blood oxygen saturation degree, the breath, the pulse rate variability information and the body movement time information, performing data transmission, displaying and recording.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a method and device for monitoring multiple physiological parameters of sleep respiration with a single photoelectric sensor. Background technique [0002] With the continuous acceleration of the pace of modern society, the quality of sleep has increasingly seriously affected the health status of individuals in all aspects of physiology and spirit. A large number of documents show that about 1 / 3 of hypertension and 1 / 5 of heart disease are caused by sleep-disordered breathing. Other complications of sleep-disordered breathing include diabetes, kidney disease, obesity, epilepsy, sexual dysfunction, and autonomic nerve function. disorder, polycythemia, and severe myocardial infarction, cerebral thrombosis, stroke, etc. Therefore, the monitoring of sleep-disordered breathing is of great significance for clinical monitoring and pathophysiological research. [0003] The routine...

Problems solved by technology

[0006] However, the pulse oximeter, which only uses photoelectric sensors to detect photoplethysmographic pulse waves, is low in cost and easy to use, but also limits its use in sleep monitoring centers of large hospitals and small and medium-sized hospitals because of the small number of detection parameters.
