Blood Alcohol Concentration Harvard Case Solution & Analysis



Blood Alcohol Concentration (BAC)
BAC refers to the amount of alcohol present in the bloodstream.

A BAC of 0.05% (point 0 five) means that there is 0.05 grams of alcohol in every 100 milliliters of blood.Amount of alcohol (ethanol) in the bloodstream used as an indicator whether or not a person is legally intoxicated and, therefore, too impaired to drive. The legal limit varies among jurisdictions (typically, from 0.05 to 0.40). BAC of 0.05 means that one-twentieth of one percent (1/2000) of blood content is alcohol.

Factors affecting the BAC

Two people who drink the same amount of alcohol might register quite different BACs. This is due to a variety of factors including body size, percentage of body fat, whether they are male or female.

Body size

A smaller person will have a higher BAC than a larger person for the same amount of alcohol consumed, because the alcohol is concentrated in a smaller body mass.

However, eating before drinking does not prevent intoxication.

Body fat

Alcohol is not absorbed into fatty tissue, therefore, people with a greater proportion of body fat will develop a high BAC more quickly than those who have lower proportions of fatty tissue. This occurs because the alcohol becomes concentrated in the smaller mass of non-fatty tissue.


Women's bodies, being generally smaller than men and with a higher ratio of fatty tissue to lean muscle, will not absorb alcohol more quickly than men's bodies do. This means that a woman drinking the same amount of alcohol, will develop a high BAC more quickly than men.



In the BAC model, I decided to implement seidl model for the analysis for blood absorption consumption, I made four analyses using seidl model, inthe first analysis,I considered gender being male and which is having height 1.63 and weight 80 and the drinking pattern is standard, he will take one standard drink after 10 minutes. drinks[] is an array which is containing the information about drinking pattern and I also described two functions, one is male seidl formula calculation, this formula is based on the universal constant value that is given in the research paper, similarly, I do the same work in female calculation and this formula takesinformation about height and weight and similarly, the second analysis is made on female in which, we consider female factor on same weight and height and if I talk about the third and fourth analyses, I made further changing in the parameter of the seidl model so third and fourth analyses are distributed between male and female but both are having same height that is 1.5 meter and same weight that is 60kg  but there is one major change in the analyses that I changed the drinking pattern, the malesand females consume 5 drinks after every 10 minutes, the result that I have found through these analyses in given below in the form of graph and description is also is given in detail under result and observations.................
