Solid-electrolyte gas sensors, originally designed for residual oxygen detection in low Earth orbit, have provided the basis for developing a multi-function sensor system for respiratory investigations. These sensors allow the detection of oxygen and carbon dioxide partial pressures simultaneously with total flow rates. Moreover, with only minor modifications, other gases of interest in cardio-respiratory testing, such as carbon monoxide and hydrogen, can be detected. The sensors are highly miniaturised and can be positioned in the mainstream of the breath. Thus there is no delay through sample transport. The characteristics of the flow detection are comparable with common sensors used in spirometry. The oxygen and carbon dioxide sensitivities have reached a level that is comparable to or even better than those of mass spectrometers optimised for respiratory analysis. Data from this sensor system allow single-breath or breath-by-breath analysis. Integrated into a portable system, the system provides greater flexibility than other devices, significantly increasing the range of scientific and health-monitoring applications.
