An overview of the several factors that determines a good alcohol

And earlier this year, the World Health Organization issued a dire warning about cancer and alcohol. No amount of alcohol is safe, the report said. So, if any alcohol raises our cancer risk, and if it might not offer a real benefit to our hearts, should we be drinking at all?

An overview of the several factors that determines a good alcohol

This guide summarizes how alcohol testers work and the factors to consider when selecting an alcohol tester. This guide also provides an overview of the four types of alcohol testers available today.

When alcohol absorbs into your blood stream, it becomes possible to determine an individual's degree of intoxication by ascertaining the alcohol concentration percentage in the person's blood -- known as "blood alcohol concentration" "BAC".

An individual's BAC can be measured two ways: Invasive testing is generally performed at health care institutions by specialists equipped to perform the procedure, while non-invasive testing is used primarily by law enforcement officials because it is more feasible to perform.

Of the different types of non-invasive testing, breath testing is the most common procedure because it is quick and less expensive.

As air moves in and out through the same set of respiratory tubes, continuous mixing of inhaled and exhaled air occurs. The bronchi separate into several subdivisions, which end in a large number of tubules.

At the end of the tubules are the alveoli, and a person's lung contains million of alveoli.

Surrounding the alveoli is a fine network of capillary blood vessels. At this level the blood exchanges chemicals with the air in the lungs. Studies show that the alcohol concentration in the lower portion of the lungs is proportionate to the concentration of alcohol in the blood at a ratio of To obtain an accurate correlation between blood and breath alcohol levels typically A person's vital capacity volume of air that can be expelled without collapsing the lung can range from 1 liter to 7 liters, depending on factors such as age, gender, physical condition, and disease status.

Typically, alcohol tester protocols will require the test subject to exhale air for at least 5 seconds to obtain a high correlation between BrAc and BAC. Newer and more advanced alcohol testers can track the force of the exhale over time to ensure an adequate lung volume is achieved.

What factors are relevant when selecting an accurate alcohol tester? Many factors should be considered when selecting an alcohol tester. First and foremost, accuracy should be an important factor unless you are merely looking to purchase a novelty item at a low cost. If you care about accuracy, then it is important to compare the accuracy levels listed in the specifications for each unit.

However, keep in mind that the accuracy reported in the specifications is often mistakenly viewed as the true accuracy of the unit when testing a human subject. The accuracies listed in the product specifications for each unit are usually based on a controlled testing environment using an alcohol simulator device.

This does not account for the ability of the alcohol tester to capture an accurate breath sample. As a result, you should consider the following factors to determine the "true accuracy" of an alcohol tester: It is a violation of federal law for a company to sell or distribute a breath alcohol detector for personal use if the device is lacking or pending FDA K clearance.

Department of Transportation DOTis responsible for testing breath alcohol testers to ensure the devices conform to the model specifications and accuracy requirements for use by law enforcement professionals throughout the USA.

Whether the alcohol tester captures a deep lung air sample and monitors pressure. The best alcohol testers are capable of detecting both the duration and force of an exhale. Most individuals can easily blow a steady breath for at least four seconds.Factors that Affect BAC July 23, 4 Comments Blood alcohol content (BAC) is a measure of the amount of alcohol that is present the blood, based on the volume of alcohol .

This is a behavioral adaptation to the effects of alcohol, and as long as the liver continues to eliminate alcohol at the rate of one drink per hour, it will have no effect on BAC.

What happens to the brain when a person takes drugs?

Being able to “Handle your alcohol” does not have any effect on BAC. Alcohol plays a role in one in three cases of violent crime. [7] In , more than 10, people died in automobile accidents in which alcohol was involved.

[8] Alcohol abuse costs about $ billion a year. [9] Even moderate drinking carries some risks. Alcohol can disrupt sleep and one’s better judgment. To feel the effects of alcohol, you have to drink more and more.

You have withdrawal symptoms after you stop drinking for too long, like shakiness, nausea, trouble sleeping, or seizures. Because so many factors affect drug response, doctors must choose a drug appropriate for each person and must adjust the dose carefully.

This process is more complex if the person takes other drugs and has other diseases, because drug-drug and drug-disease interactions are possible.

Why do some people react differently to alcohol than others? Individual reactions to alcohol vary, and are influenced by many factors, such as: Age.

Sex.

How Does a Breath Alcohol Test (Breathalyzer) Work?

Race or ethnicity. Physical condition (e.g. weight, fitness level). Amount of food consumed before drinking. How quickly the alcohol was consumed. Use of drugs or prescription medicines.
