HOW ACCURATE IS THE DETERMINATION OF ALCOHOL CONCENTRATION FROM BREATH TESTS?

WIE GENAU IST DIE BESTIMMUNG DER ALKOHOLKONZENTRATION IN DER ATEMLUFT?

RESEARCH INTO ALCOHOL AS THE CAUSE OF ACCIDENTS HAS UP TO NOW BEEN DIFFICULT AND COSTLY BECAUSE OF THE PROBLEMS ASSOCIATED WITH THE DETERMINATION OF BLOOD ALCOHOL CONCENTRATION (BAK). IN RECENT TIMES HOWEVER VARIOUS TYPES OF EQUIPMENT HAVE BEEN DEVELOPED AND TESTED WHICH PERMIT RELIABLE ESTIMATION OF BREATH ALCOHOL CONCENTRATION (AAK). FOR INSTANCE IN THE UNIVERSITY OF WALES COMPARATIVE TESTS OF BLOOD AND BREATH ALCOHOL WERE CARRIED OUT, IN WHICH BAK WAS DETERMINED FROM CAPILLARY BLOOD SAMPLES WITH THE PERKIN-ELMER F 11 GAS CHROMATOGRAPH, AND THE AAK WITH THE ALCOMETER AE-D 1. THE TESTS WERE CONDUCTED ON A SAMPLE OF 40 PERSONS AND SHOWED A CLOSE CORRELATION BETWEEN BAK AND AAK. AN APPARATUS HAS BEEN DEVELOPED IN THE UNIVERSITY OF KARLSRUHE WHICH USES THE PRINCIPLE OF SPECTRAL PHOTOMETRY, AND THE INITIAL TEST RESULTS ARE VERY PROMISING. ON THE BASIS OF THE CLOSE CORRELATION WHICH MAY BE ACHIEVED EVEN TO-DAY BETWEEN BAK AND AAK IT APPEARS SENSIBLE TO EMPLOY SUITABLY TESTED AND CALIBRATED BREATH APPARATUS IN ACCIDENT RESEARCH.
