õhuproov

Õhuproov, also known as a breath test or breathalyzer test, is a method used to determine the presence and concentration of alcohol in a person's breath. It is commonly employed by law enforcement to assess whether an individual is under the influence of alcohol. The test works on the principle that alcohol is released into the breath as it is metabolized by the body. The breath sample is then analyzed using a chemical sensor, typically a fuel cell or infrared sensor, which measures the amount of alcohol present.

Õhuproov tests are widely used due to their convenience, speed, and relative accuracy. They are non-invasive and can provide results within a few minutes. However, they are not foolproof and can be affected by various factors, including the individual's hydration level, the type of alcohol consumed, and the time elapsed since drinking. Additionally, some individuals may have medical conditions that interfere with the accuracy of the test.

Despite these limitations, õhuproov tests remain a valuable tool in traffic enforcement and other situations where the presence of alcohol needs to be determined. They are often used in conjunction with other methods, such as blood or urine tests, to ensure a more accurate assessment of an individual's blood alcohol concentration.
