Design outcomes

Primary

Measure	Time frame
Detection of oxygen induced changes in exhaled breath gas composition due to oxidative stress. Demonstrated by measurements with the modified metal oxide sensor array at time points 0.5h, 4h, and 24h following test gas breathing.	—

Secondary

Measure	Time frame
Detection of oxygen induced changes in exhaled breath gas composition due to oxidative stress. Demonstrated by measurements with GC-MS (Gas Chromatography Mass Spectrometry) at time points 0.5h, 4h, and 24h following test gas breathing.	—
