摘要
Abstract
Objective:To research the quality control and testing methods of polysomnography and to ensure its safe and effective performance.Methods:A quality control testing method was designed for the main indicators of EEG signal,EMG signal,ECG signal,and pulse oxygen saturation of polysomnography.In August 2023,two polysomnography instruments of the same brand and different models(marked as Test Equipment A and Test Equipment B)in clinical use in Daping Hospital,Army Medical University were selected.The quality control testing of polysomnography instrument was conducted by using electroencephalogram calibration instrument and vital sign simulator to evaluate the reliability of the performance of polysomnography.Results:A quality control testing method was developed for quality control testing of polysomnography aiming at the repeatability of the indicated values of EEG signals,EMG signals,ECG signals,and pulse oxygen saturation of polysomnography.Except for the output value of 2 mV of the voltage measurement simulator of test equipment B,the relative error of the recorded data was-11%,and the parameters were out of tolerance,and the rest of the test data of test equipment A and test equipment B met the maximum limit output value of the national metrology verification regulations and the technical requirements of the equipment manufacturer.Conclusion:The quality control detection method of polysomnography can evaluate the performance parameters of the selected testing equipment A and testing equipment B,and provide technical support for the quality control detection and safe use of such equipment.关键词
