Parameters:
(1) blood alcohol concentration in mg/dL at 2 hours after the exposure
(2) body weight in kilograms
estimated dose of ethanol in grams per kg =
= ((blood alcohol concentration in mg/dL at 2 hours) + 28.89) / 148.5
= (0.006734 * (blood alcohol concentration)) + 0.1945
estimated dose of ethanol in grams =
= (body weight) * (estimated dose of ethanol in grams per kg)
where:
• Ideally the fat free body mass should be used rather than the actual body weight. The study appears to have used young male volunteers.
• Calculating fat free mass can be done as outline if the previous section or it can be measured using bioelectric impedance.
• The volume of alcohol ingested can be estimated if the proof is known.
Limitations:
• Testing was done on male volunteers.
• The blood sampling is done 2 hours after the exposure. Adjustments would need to be made for specimens collected later.
• Ingestion of alcohol is often done over a period of time rather than a single bolus.
