Self-Test for Breath Alcohol
An estimate of your blood alcohol concentration (BAC) is determined with a breath alcohol test. This test measures the amount of alcohol in the air stream that you breathe out (exhale). A simple hand held device is available enabling you to measure breath alcohol level on yourself. The device can provide a correct estimate of your blood alcohol level if calibrated and used in accordance to the manufacturer's instructions. This home machine is similar to, though not as exact as, the type of test used by police for suspected drunk drivers.
Your blood alcohol concentration starts to rise within minutes of drinking alcohol. Alcohol is absorbed directly through the walls of the stomach and then travels into the bloodstream, and moves throughout your body to your brain. This quick absorption allows blood alcohol levels to increase rapidly.
Alcohol levels in your blood reach its highest level approximately 60 minutes after being consumed. However, food in your stomach may slow down the absorption rate, taking it longer for the blood alcohol to reach its highest level. Alcohol is mostly broken down in the liver and the rest of it is passed out of your body in urine and your exhaled breath. You can purchase breath alcohol devices to measure your breath level at many pharmacies or through the Internet.
The manual breath alcohol device is a glass tube (or a balloon and a glass tube) which contains crystals that will change color when exposed to alcohol from your breath. This manual device is much simpler and less costly than electronic meters.
The electronic meter displays the blood alcohol concentration (BAC) percentage in a digital display window after the glass mouthpiece attached to the meter is used. This type of meter is more expensive than the manual type.
Many bars and restaurants provide their customers with free alcohol breath tests using one of these two methods. The devices are also used to monitor people in an alcohol rehabilitation center or hospital.
The breath alcohol self-test is used to estimate your blood alcohol concentration (BAC). The results can help you decide whether it is safe to drive. This estimate of blood alcohol is not intended to represent your actual driving abilities. Your driving may be impaired even with a low BAC level, such as below 0.05.
The breath alcohol test offers one piece of information to help you make a safe decision about drinking and driving. The safest decision is always not to drive if you have been drinking.
Blood alcohol concentration (BAC) is regularly used by police to determine whether a person is legally impaired and therefore should not be behind the wheel of a vehicle. A blood alcohol concentration in the range of 0.05 to 0.10 is considered legally impaired throughout most of the United States. However, legal BAC levels vary from state to state.
Driving under the influence of alcohol (DUI) can be deadly. Alcohol is involved in nearly half of all fatal highway accidents. Even mild intoxication can impair your ability to drive safely. At 0.06 BAC, your judgment and physical coordination are impaired. At a BAC of 0.08, your muscle coordination and driving ability are significantly impaired.
Having a calculable amount of alcohol in the blood can mean that judgment and reflexes are compromised. You can buy breath alcohol tests through the Internet, either directly from the manufacturer or from a company promoting these types of products. To find this type of device on the internet, simply search using the type of test or with the name of the manufacturer.
