1 Blood alcohol concentration and psychomotor effects
S.A. Grant, K. Millar, G.N.C. Kenny  British Journal of Anaesthesia  Volume 85, Issue 3, Pages (September 2000) DOI: /bja/ Copyright © 2000 British Journal of Anaesthesia Terms and Conditions

2 Fig 1 Variability of peak breath estimated blood alcohol concentration and subsequent decay in 12 volunteers after administration of a standard, oral dose (0.75 ml kg−1). British Journal of Anaesthesia  , DOI: ( /bja/ ) Copyright © 2000 British Journal of Anaesthesia Terms and Conditions

3 Fig 2 Variability of breath-estimated blood alcohol concentration in 12 volunteers after administration of continuous intravenous infusions to maintain target blood concentrations of 20, 50 and 80 mg 100 ml−1.

4 Fig 3 Prediction error of breath-estimated blood alcohol concentration (%) at various directly measured blood alcohol concentrations between 45 and 90 mg 100 ml−1. An underestimate of blood alcohol concentration by the breath estimate is expressed as a positive prediction error. Mean prediction errors at 50 and 80 mg 100 ml−1 target concentrations are displayed as solid lines.

5 Fig 4 Deterioration in choice reaction time recorded in milliseconds in 12 volunteers with increasing blood alcohol concentration. Values are means (5–95% confidence interval). Alcohol groups: oral dose, maximum blood concentration following the oral dose; ‘20 mg’, ‘50 mg’ and ‘80 mg’ are target concentrations of 20, 50 and 80 mg 100 ml−1, respectively.

6 Fig 5 Deterioration in secondary reaction time recorded in milliseconds in 12 volunteers with increasing blood alcohol concentration. Values are mean (5–95% confidence interval). Key as in Figure 4. British Journal of Anaesthesia  , DOI: ( /bja/ ) Copyright © 2000 British Journal of Anaesthesia Terms and Conditions

7 Fig 6 Deterioration in tracking performance recorded as a percentage of time on target in 12 volunteers with increasing blood alcohol concen tration. Values are mean (5–95% confidence interval). Key as in Figure 4. British Journal of Anaesthesia  , DOI: ( /bja/ ) Copyright © 2000 British Journal of Anaesthesia Terms and Conditions
