Table 1

Monomer, dimer, and total acetone intensity (mV).


	Intensity (mV)			Dimer (%)	Concentration (ppb_v)
	Monomer	Dimer	Total	Dimer (%)	Concentration (ppb_v)

Intensive care unit	40 (37–46)	22 (18–27)	84 (70–97)	48 (46–50)	5.1 (4.4–5.5)
Laboratory	74 (52–96)	21 (17–25)	116 (88–144)	44 (39–48)	5.6 (5.1–6.2)^#
Critically ill patients	15 (12–18)	106 (85–126)	226 (185–268)	90 (89–91)	9.5 (7.9–11.1)
Rats	6 (6-6)	127 (118–135)	259 (241–276)	95 (95-96)	10.3 (9.7–10.9)

Monomer, dimer, and total acetone intensity ((mV); total acetone intensity (mV) = acetone monomer intensity (mV) + (2 acetone dimer intensity (mV))), dimer peak fraction of total acetone peak intensity, and concentrations (ppb_v) in ambient air of intensive care unit, laboratory, critically ill patients, and rats. Data are expressed as means (95% CI); significant higher concentration of volatile acetone in laboratory vs. intensive care unit (Mann–Whitney rank sum test); significant different intensities and concentrations of volatile acetone in critically ill patients vs. rats (one-way ANOVA).
