The ability to quickly estimate BrAC by medical personnel in emergencies has been found useful in several investigations (Gentilello et al., 1999; Gibb, Yee, Johnston, Martin, & Nowak, 1984; GW et al., 2006; Jurkovich et al., 1992; Kaisdotter Andersson et al., 2015; Sebbane et al., 2012). The low-cost and ease of use in analyzing breath alcohol makes it a useful tool for medical staff and first responders. In medicine, there are situations where administering drugs to a person with alcohol present in their system could result in adverse drug reactions (Moore, Whiteman, & Ward, 2007). Screening patients for alcohol with one of the instruments included in this study could help medical personnel triage patients (Indig, Copeland, Conigrave, & Rotenko, 2008) and avoid adverse drug interactions.
