Breathalyzer Scale – Standard Measurement for BAC

Breathalyzer is a tool or device that is used to measure the blood alcohol content (BAC) of a person. The person would need to blow on the mouthpiece of the device and after a short while (usually seconds), the breathalyzer will provide the BAC result in percentage. Previously, breathalyzer is the brand name of such alcohol tester but later on, it has been used to name such kinds of devices regardless of the manufacturer. Today, breathalyzer scale is being used by the police in the observance of DUI laws. It is also used by health care institutions, schools, and other establishment for security purposes.

Blood Alcohol Content (BAC)

Basically, BAC measures the alcohol content in the human body through the blood. When a person drinks alcohol, it goes through the throat then into the stomach and intestines. After that, the toxin goes straight into the bloodstream. As the blood is carried to all parts of the body like in the lungs, a parcel of the alcohol stays across the lung membranes. When the person breathes, it evaporates and goes out through exhalation. Breathalyzers make use of semi-conductor, platinum, or cell fuel sensors to measure the BAC of the suspect.

The reading in a breathalyzer scale is shown through a numerical reference in percentage such as 0.20%. This means that 20 percent of the person under check-up is intoxicated with alcohol. In many states, allowable BAC is only until 0.08%. Exceeding this level is already a violation of the DUI laws. It is insignificant to measure the intoxication rate of a person based on how much drinks he consumed. The reason for that is alcohol tolerance and physiology of a people varies. That means this person can drink 10 glasses of beer without getting drunk and but that person only takes 3 glasses and he gets smashed already. Nonetheless, according to studies, drinking 2 regular drinks increase the person’s BAC by 0.05% (but of course, this can be affected by the gender, weight, body type, and overall physic of a person).

Using breathalyzers, authority can easily identify those who are getting detrimental to public safety by wandering or driving drunk. This in turn, reduces rates of accidents such as car crash and delinquencies.
