Systems and techniques for the analysis of gases for medical purposes are described. In one aspect, a system includes a sample collector to collect a physical sample associated with an individual and present a gas sample for analysis, a gas analysis device to analyze the gas sample presented by the sample collector to determine a concentration of one or more non-aqueous gases in the gas sample, a data storage device that includes information reflecting a correlation between concentration of the one or more non-aqueous gases in the gas sample and a disease state, and a data analysis device to determine a medical condition of the individual based on the concentration of one or more non-aqueous gases in the gas sample and the information.本發明係揭示用於醫療目的之氣體分析系統和技術。本發明中的一個部分係關於一種系統,其包括收集與個體有關的生理樣品並提供用於分析的氣體樣品之樣品收集器、分析該樣品收集器所提供的氣體樣品以測定該氣體樣品中之一或多種非水性氣體的濃度之氣體分析裝置、包括反映該氣體樣品中之一或多種非水性氣體的濃度與病況之間關聯性的資訊之數據儲存裝置,及根據該氣體樣品中之一或多種非水性氣體的濃度及資訊判定該個體的醫療情況之數據分析裝置。100...氣體分析系統105...樣品收集器110...氣體樣品製備裝置115...氣體分析器120...數據分析器125...輸出裝置
