A study concerning the blood/breath alcohol conversion factor Q: concentration dependency and its applicability in daily routine
Pavlic,M.; Grubwieser,P.; Brandstätter,A.; Libiseller,K.; Rabl,W.;
The conversion factor Q, obtained by division of blood alcohol concentration (BAC) by breath alcohol concentration (BrAC) is a widely discussed topic due to its great variance. By Austrian law, regulations frequently require an estimation of a corresponding BAC by a measured BrAC. It is known that Q depends among other things, on the alcohol kinetic state of the person being tested, which mathematically can be transformed to a dependency on the BrAC.
