Determining a patient’s BAC can be crucial in specific emergencies like altered mental status. If left unmeasured and untreated, an individual can experience severe impairment, alcohol poisoning, coma, and even death. There is never an acceptable BAC level to operating a car or other vehicles. Blood alcohol concentration (BAC) is the metric used in measuring how much alcohol is in your bloodstream. More specifically, BAC measures how much alcohol per 100 milliliters of blood. If you have a blood alcohol level of 0.05, that means that there is 50 mg per dL of alcohol in your system, or 0.05%.

When it comes to alcohol and safety, blood alcohol content (BAC) is an important metric that helps determine a person’s level of impairment. When alcohol enters the body it enters the stomach and small intestine and then gets absorbed directly into the bloodstream. Alcohol is a toxin, and will stay in the bloodstream until it’s eventually filtered out by the liver.

For the travelers out there, it’s important to note that some countries worldwide have zero-tolerance policies or BAC limits well below that in the United States. The number of drinks you’re consuming is an important factor in determining your BAC, but the size and strength of those drinks can matter just as much. That generous glass of wine may actually be considered two drinks. Sip your drinks, and incorporate non-alcoholic beverages in between each one.

Blood alcohol concentration (BAC) is a measure of the amount of alcohol that is present the blood, based on the volume of alcohol consumed over a given period of time. A BAC of .10% means that an individual’s blood supply contains one part alcohol for every 1000 parts blood. BAC can range anywhere from 0.01% (slightly “feeling it”) to 0.30%+, which is dangerously high.

Factors That Impact BAC

If you have questions or concerns about your results, talk to your healthcare provider and/or a lawyer, depending on your situation. A provider then sends the samples to a lab where a medical laboratory scientist prepares the samples and performs the tests on machines known as analyzers. This is the point at which a person is over the legal limit for driving and can be liable to public intoxication charges. Common patterns include risky behavior, boisterousness, and the possibility of nausea and vomiting. Reflexes, reaction time, motor control, and speech can become impaired. A blood alcohol level chart shows how your bac depends on: much impairment begins as soon as you have a drink.

A person should consider getting a ride home if they intend to drink two or more drinks. For more information about alcohol metabolism, check out our alcohol metabolism page. Use support groups, therapy, medications, or other strategies that fit your needs.
