What Are Blood Alcohol Levels?Blood Alcohol levels are the measurement of alcohol within a person*s system. It is commonly measured by the Blood Alcohol Concentration which refers to the percentage of alcohol that is found within one*s bloodstream or breath.
The breathalyzer is one of the methods performed commonly by authorities in order to determine if one is legally intoxicated or not though there are multiple methods used in order to determine someone*s blood alcohol level units and percentage of consumption.
It is also used during life-threatening situations where someone can have the possibility of gaining alcohol poisoning due to high levels of alcohol in their blood.
Blood Alcohol Concentration is expressed as the weight of ethanol (in grams) in 100 milliliters of blood or 210 liters of breath.
This can be measured by breath, blood or even urine tests. There are many indicators that would normally indicate someone being intoxicated such as feeling relaxed as in euphoria, impairment or irrational judgment, lowering of caution and the slow or complete loss of memory.
As the blood alcohol levels steadily rise, so does the effects and cautions that go along with it. Soon, someone*s vision can become extremely disorientated or one might have difficulties in hearing.
Speech patterns start to break and slur as the mind starts to slow down. Reaction time might be slow and soon enough, lack of physical control.
Each person has a different state when intoxicated and that is also a difficulty when figuring out whether someone is intoxicated enough that they need someone*s aid and even some people might have violent reactions when intoxicated which would bring a danger towards their surroundings.
How Is The Blood Alcohol Level Calculated?There are many factors affecting someone*s Blood Alcohol Level such as biological features such as sex, medications, body weight and food (to a lesser extent) but is mostly affected by the amount of alcoholic drink consumption and the time between each drink consumed.
Blood alcohol content levels formula
Under Illinois Law, the level of an individuals blood alcohol concentration will lead to certain presumptions on whether someone is considered legally drunk for the purposes of driving under the influence of alcohol.
If your blood alcohol concentration is a .0 * .04999 then you are presumed to not be under the influence of alcohol.
If your blood alcohol concentration is a .5 * .07999 then there is no presumption on whether you are under the influence of alcohol and the court must look to other factors to determine if you have committed the offense of driving under the influence of alcohol.
If your blood alcohol concentration is a .8 or above then you are presumed to be under the influence of alcohol.
It is important to remember that if your blood alcohol concentration is a .049 or below you can still be charged with driving under the influence of alcohol in Cook County.
It is also important to know that even if you are presumed to be under the influence of alcohol (a blood alcohol concentration of .08 or above) that does not mean you are guilty of driving under the influence of alcohol.
The prosecutor still needs to prove their case and there are other factors the judge must consider as well.
A normal drinking alcohol level would be one or two drinks of 12 Oz. Beer but any more than that would immediately be listed as under the influence of alcohol A person*s body weight and sex are especially calculated due to the fact that it greatly affects the alcoholic metabolism of each person.
Blood Alcohol Concentration Chart
There are plenty of BAC charts and calculators available. Most of these can be found on the internet and are based on basic things that determine one*s blood alcohol level through charts such as weight, sex and the quantity of the drink consumed.
They also provide small descriptions of effects when intoxicated enough. One of the few drawbacks from this method is that it makes based assumptions regarding the strength of the drinks one has consumed, generally relying on weight and sex.
Most of these charts don*t take into account someone*s metabolism, health, medication and recent consumption of food. They*re also a bit problematic to search for once someone is already intoxicated since they have little to no control with their physical state. These Blood Alcoholic level charts are only for basic use and aren*t personalized enough in order to create the most accurate measurements. Here are some examples of Blood Alcohol Concentration charts.
