BAC is the abbreviation for Blood Alcohol Concentration. BAC generally refers to the measure of alcohol levels in a human body. Usually BAC is expressed in terms of alcohol grams in each 100 milliliters of blood. For instance, where the BAC is 0.05, it means that alcohol content in each 100 milliliters of blood is 0.05 grams. BAC is usually measured using blood or urine samples, though it may be measured through breath. Usually, it will take a healthy person of average size about sixty minutes to process a standard alcoholic drink. However two persons to take the same quantity of alcohol are likely to have varying BACs because alcohol is processed at varying rates in each person. A persons BAC is influenced by the quantity of alcohol taken and the duration within which it is taken. Where a lot of alcohol is taken over a short period of time, the BAC tends to be higher than in situations where the same amount is taken over a prolonged duration of time.
Other factors influencing BAC levels
A person’s BAC is also affected by factors such as age and gender. Because body composition varies between male and female, the same quantity of alcohol can lead to BAC levels that are higher in men than in women. Also, younger persons attain higher levels of BAC much faster compared to older persons. This is because metabolism happens faster in younger people than in older people. The body size also affects BAC levels. A big person usually has a lot of blood that helps dilute alcohol and this takes longer to attain BAC levels similar to that of a smaller person. Muscles also absorb alcohol while fat doesn’t hence the more fat a person’s body has, the easier it is for their BAC to rise. Liver functionality also influences BAC levels because a damaged liver is unable to process alcohol content efficiently cause BAC levels to rise.
