Abstract:
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.
