How does a breathalyzer work?

When a person consumes alcohol, that alcohol that a person drinks shows up in the breath because it gets absorbed from the mouth, throat, stomach and intestines into the bloodstream. Alcohol is not digested upon absorption or chemically changed in the bloodstream. As the blood goes through the lungs, a physiologically predictable amount of the alcohol will moves across the lung membranes and into the lungs themselves.

    Does Alcohol Causes Intoxication

    Alcohol is a drug found in beer, wine, and liquor that causes intoxication. Alcohol can impair a person’s physical and emotional state. Intoxication is the physical and mental changes produced by drinking alcohol (Friedman, Stine, and Whaten 2242). Some people believe that beer and wine are safer than liquor which leads them to believe that it is okay to drink. The truth is that one 12 ounce bottle of beer or a 5 ounce glass of wine is equal to the amount of alcohol in a 1.5 ounce shot or liquor and can cause the same effects (“Facts About Alcohol”). Short term effects of alcohol include nausea, vomiting, dehydration, coma, death, blackout, memory loss, poor vision, reduced reaction time, and loss of judgement along with self control (Friedman,…

    Mandatory Breathalyzer Test Argument Analysis

    In May 2014, Northern Secondary School principal Ron Felsen proposed to implement a mandatory breathalyzer test in order to prevent students from consuming alcohol prior to the prom. However, students believed that the conduct of the breathalyzer test would infringe their constitutional rights. As far as I concerned, the breathalyzer test before gaining entry to prom should not be administer since it will be an invasion of students privacy and dignity. The purpose of the policy of compulsory breathalyzer test is to have a sobering and healthy prom, which means students should not be intoxicated. The legal drinking age is 19 years throughout Canada, except for Quebec, Manitoba and Alberta. The propose of mandatory breathalyzer test put almost every students who…

    Almost all jobs and companies require a drug test before hiring you as an employee. So there is no reason a person requesting public assistance should not be required to pass a drug test as well. I don't mean random drug testing either. Make it a requirement to receive their benefits. Our country cannot continue to waste money and expect taxpayers to support them. Enough is enough. If we sit back and allow the public health system to run this way, we run the risk of not being able to help anyone in the future. Unfortunately there are people that do not want to help themselves or cannot help themselves. After all, this is an addiction and can be very hard to kick. Testing…

    How Breathalyzers Work

    The most common scene that we see on TV is when somebody gets pulled over then a certain cop asks, “Have you been drinking?”. Cops frequently use breathalyzers to measure the amount of alcohol in a driver’s breath because it’s considered a more accurate type of sobriety test. Alcohol is not immediately digested, it remains in the bloodstream after it has been ingested. Part of the blood passes in the lungs where traces of alcohol are released along with the expelled air and instantly detected by the breathalyzer. It consists of three things: a sampling system, a reaction chamber with two vials, and a detector.…

    Personal Narrative: A Safer World

    The number of fatalities will decrease drastically and so would the number of injuries. If breathalyzers were installed, it would also save the government and drivers a lot of money. The government would not have to pay 132 billion dollars a year towards the cost of drunk driving accidents. Drivers would not have to pay for DUI fines and the cost of their insurance going up. Lastly, putting breathalyzers in cars would prevent people from getting arrested and getting DUIs, which would ensure that they do not lose their job or keep them from finding a job after they do jail time for causing an accident or killing someone. Putting breathalyzers in cars would simply keep the roads safe for…
