Abstract: Exhaled breath analysis offers a non-invasive method for assessing respiratory health. Carbon dioxide (CO2) levels can indicate various physiological conditions, making its detection crucial in numerous biomedical applications. Such a non-invasive diagnosis is possible with a detector that utilises a pH-sensitive indicator that changes colour based on the CO2 concentration in exhaled breath. This colourimetric sensing element comprises a pH-sensitive polymer film containing basic or acidic groups that react with exhaled breath, causing a colour shift. The chosen dye exhibits a significant change in absorbance upon exposure to CO2, enabling its sensitive detection. As the CO2 levels rise or fall during inhalation and exhalation cycles, the indicator transitions between representative colours, allowing for breath-by-breath monitoring. This paper presents a simple and efficient method for monitoring CO2 levels in exhaled breath based on a disposable, colourimetric end-tidal CO2 (ETCO2). The rapid and reversible color change of the non-toxic indicator offers a promising tool for various bio-medical applications requiring real-time ETCO2 monitoring.
