Samenvatting
The effects on BAC reading caused by differences in volume of sample delivered, exhaled breath temperature, and alteration of breathing style just prior to delivery, were studied. The variables of BAC, volume, temperature and pressure were measured over the delivery of a breath sample at a rate of 4 times per second in 14 drinking human subjects using two specially modified Draeger Alcotest 7110 breath alcohol analysers. This paper presents the results of the study.
