Simple vs. sophisticated models of breath alcohol exhalation profiles

Lubkin, S. R. and Gullberg, R. G. and Logan, B. K. and Maini, P. K. and Murray, J. D. (1996) Simple vs. sophisticated models of breath alcohol exhalation profiles. Alcohol and Alcoholism, 31 (1). pp. 61-67.



For medicolegal purposes, breath alcohol content is typically determined from an end-expiratory sample. Measurements obtained by this method necessarily underestimate the alveolar breath alcohol content, and therefore underestimate the blood alcohol content. We suggest and analyse an improved paradigm which uses the entire time-series of breath alcohol measurements during exhalation, not simply the last recorded value. We present two mathematical models for the exhaling lung, and discuss the implications of each for more accurate and therefore more reliable breath alcohol measurement.
