The analysis and management of the diaphragmatic EMG signal / 医疗卫生装备

ABSTRACT

The method of triggering the respirator to perform airfeed by the management of the diaphragmatic electromyography (EMG) signal is introduced in this paper. By using LabVIEW, an analysis software of the diaphragmatic electromyographic (EMG) signals is developed to filter the diaphragmatic EMG signal. The characteristics of the filtered signal is analyzed to catch the inspiratory onset, and then a series of signals are sent out duly to trigger the respirator to perform airfeed, and thus the patient's respiration can be synchronized with the respirator.
