abstract="We describe a novel mouth-cup device for sampling breath from unconscious subjects and analysis with a hand-held breath-alcohol instrument, the &quot;Alcolmeter SD-2.&quot; This equipment was evaluated in healthy volunteers after they drank a moderate dose of alcohol. Three kinds of breath were analyzed: (a) end-expired air from a conventional mouth-tube, (b) breath sampled from the mouth-cup, and (c) air from a nasal tube supplied with the breath analyzer. The ethanol concentration in breath from the mouth-cup was slightly less than in end-expired air but significantly greater than in nasal air. <br><br>RESULTS with mouth-tube and mouth-cup correlated highly with blood-ethanol concentration as determined by gas chromatography; nasal-tube air correlated less well. The Alcolmeter responded not only to ethanol but also to methanol, 1-propanol, and 2-propanol, whereas ethylene glycol gave no response. The time-response curve for methanol was different, and this might permit differential diagnosis of methanol poisoning.<p /><p>Language: en</p>",
