Abstract :
The present work introduces the validation results for assessment of End-tidal carbon dioxide (EtCO2) concentrations and breathing patterns from a new ultrafast colorimetric sensor. The performance of the new sensor is compared to an infrared carbon dioxide commercial analyzer. Correlation analysis of EtCO2 levels from both methods indicated an accuracy of nearly 100%, with a correlation coefficient >0.85. In addition, the capability of the new sensor to discriminate between normal and abnormal breathing patterns was assessed via comparative paired t-test. The overall performance of the new sensor is satisfactory, and opens the possibility of low-cost and ambulatory respiratory analysis for patients with respiratory diseases.
