abstract="The influence of the breathing technique (hypo- and hyperventilation) used in breath alcohol measurement using the Alcotest(registered trademark) 7110 MKIII Evidential is significantly reduced if not ruled out altogether by correcting the breath alcohol concentration (BrAC) to a standard temperature of 34(degrees)C (hyperventilation from - 11% to - 2%; hypoventilation from + 13% to + 7%). The BrAc deviation on hypoventilation correlates significantly with the time of hypoventilation (p lt 0.001). Besides temperature related alteration of alcohol saturation in breath, the time of alveolar contact seems to play an additional role. In hyperventilation compared to normoventilation the time of alveolar contact is only marginally reduced, therefore being of secondary importance in this context.<p />",
