[Design and Verification of a Human Energy Metabolism Detection System Based on Breath-by-Breath Method].

Year: 2025

Type: other

Abstract: Objective: To accurately measure human energy metabolism with high temporal resolution, a respiratory gas analysis system was designed using a breath-by-breath approach. Methods: were calculated through respiratory characteristic alignment and respiratory signal segmentation. Finally, metabolic indexes were calculated according to the Weir formula. Furthermore, a controlled trial was formulated for validation comparisons with the MGC ULTIMA SYSTEM PFX CARDIO2. Results: The results indicate that the data points of metabolic indexes measured by this system all fall within the confidence interval when compared with those of the MGC. Conclusion: The system has high consistency with the MGC measurement results. Thus, the system can accurately measure metabolism in real-time and provide data support for clinical nutrition assessment and therapy.
