摘要
目的研制一种能够提供准确、实时检测结果的主流式呼吸末二氧化碳（ET—CO2）检测装置。方法采用ADμC7026作为中央处理部件，用于进行数据预处理、温度补偿和非线性校正，得到ET—CO2浓度值、呼吸波形和呼吸率。结果经实验结果分析，该系统运行稳定，响应较快，可重复性好，精度高，满足设计要求。结论基于ADμC7026的ET-CO2检测装置测得的数据准确可靠，可以为危重患者监护、麻醉手术监护、小儿呼吸监护等方面提供更加准确的实时数据。
Objective To develop one kind of mainstream ET-CO2 （carbon dioxide of the expiration tip）detector which provides accurate and real-time testing results. Methods Applying ADμC7026 as central processing unit for data pre-processing, temperature compensation algorithm and non-linear correction, the ETCO2 concentration, respiration waveform and respiration rate were obtained. Results The analyzing results of the experimental data shows that the system meets the design requirements with fine stability, rapid response, good repeatability and high accuracy. Conclusion ET-CO2 detector based on ADμC7026 makes the detection of CO2 more accurate and reliable, which provides more accurate real-time data for critical patient monitoring, anesthetic care, pediatric respiratory care and so on.
