Abstract

The invention discloses a sleeping posture identification method based on bioelectrical impedance. The method comprises the following steps of: acquiring electrical impedance signals of the left and right chests of a testee; performing analog-to-digital conversion on the electrical impedance signals of the left and right chests respectively to obtain digital electrical impedance signals of the left and right chests; extracting reference feature values according to the digital electrical impedance signals of the left and right chests; identifying the sleeping postures of the testee by adopting a hierarchical support vector machine classification method according to the reference feature values. The method is simple and easy, has a good anti-interference effect and can be used for quickly and accurately identifying the five main sleeping postures of the testee.

Description

technical field [0001] The invention relates to the technical field of medical monitoring, in particular to a sleep posture recognition method based on bioelectrical impedance. Background technique [0002] At present, in the clinical sleep monitoring technology for patients, the monitoring equipment is bulky and the operation is complicated, and the patient needs to be in a specific place, such as a sleep monitoring center. Detection, therefore, is less operational for real-time monitoring of patients. Specifically, when detecting the sleeping posture, equipment such as an acceleration sensor is often used, and the patient is detected by a method of monitoring the posture through a separate sensor. However, too much monitoring equipment can easily cause discomfort to patients and affect the quality of sleep of patients. [0003] A method for monitoring sleep apnea using bioelectrical impedance technology has been proposed in the prior art, but in this method, a method or ...
