I’m sitting here at my desk with a very strong odor of acetone on my breath all day. Five paired blood and breath samples were obtained from each child over a 6 hour period. Breath concentrations of acetone in type 2 diabetic subjects undertaking a long-term dietary modification programme were studied. Professor Sotiris E. By creating films of poly(4-vinylbenzeneboronic acid) and poly(allylamine hydrochloride), acetone can react with these via a Petasis reaction. Among those with higher simultaneous blood-sugar levels the mean acetone concentration was abnormal and rose progressively with the blood-sugar. Breath humidity increases the conductivity of the sensing materials and therefore, lowers the sensors response to acetone.
The breath acetone level in controlled diabetic patients was in the range between 0.19 and 0.66 ppmv, where its concentration in medically untreated type-2 patient was 0.92 and 1.20 ppmv. Recently, breath isoprene was proposed as a noninvasive marker of free
