Development of compact optical oxygen and carbon dioxide gas sensors for portable metabolic analyzers Sebastian, Ezra

Abstract

Metabolic analyzers measure oxygen (O₂) consumption and carbon dioxide (CO₂) production, which are imperative in the assessment of human physiology and overall health. In the case of respiratory illness such as COVID-19, the respiratory rate of patients is an important indicator for both potentially fatal states and determination of the corresponding lifesaving treatments. Optical sensors have uniquely small form factors that allow for health monitoring outside of hospital or laboratory settings. This research was targeted to enhance the portable metabolic analyzers produced by VO₂ Master, which was the partner company in this research. The goal of this research was to investigate the viability of optical and simultaneous sensing of CO₂ gas and O₂ gas in a portable metabolic analyzer.
