Almost everyone has heard the word "promille". It is used by the heroes of detective films, doctors operate on it, it excites beginners and experienced motorists. What is it and what is the indicator used for?

This coefficient is used to determine the presence of alcohol in the blood, the level of its content and the degree of intoxication. It is widely used in medicine, pre-trial and judicial proceedings.

Term meaning and calculation example

The term "ppm" refers to the concentration of ethyl alcohol in relation to the total volume of blood. The word comes from the Latin “pro mille”, which translates as “for a thousand”. So what is ppm? This is conditional 1\1000. The designation "‰" should not be confused with "%" (percentage). The word does not decline.

You can calculate the approximate amount of ethanol contained in the body according to the following scheme.

The body contains water about 70% of the total mass. That is, in a man weighing about 100 kg, 70 liters of fluid support vital activity. If this man drinks 1 liter of intoxicating drink with a strength of 5%, then 36 g of ethyl alcohol will enter his body. To obtain the result of interest, you need to divide 36 by 70, that is, the ethanol content in the blood will be 0.51. Such a ppm will correspond to reality 30 minutes after drinking alcohol.

Endogenous concentration of ethanol - what is it? This is the natural content of alcohol in the blood, up to 0.3 ‰. The indicator is observed without the intake of ethyl alcohol from the outside. Such a per mille of intoxication and clouding of consciousness does not cause. In some cases, the concentration drops to 0.001 ‰, it is at such moments that a special craving for alcoholic beverages arises. Doctors associate the tendency to alcoholism with a reduced endogenous content of ethanol. As a rule, this phenomenon is observed in children whose parents abused. The decrease in this indicator to 0.05 ppm explains the craving for a glass in the morning, after drinking the day before, this is one of the first bells that you should not turn a blind eye to.

Effect on the body

Promille is a unit of measure for the content of alcohol in the blood, it illustrates the degree of negative impact of ethyl alcohol on the body, depending on its concentration.

Since the negative impact of alcoholic beverages is most significant for drivers and persons related to complex mechanisms, on their example, the change in consciousness with an increase in the level of alcohol will be considered.

0.3-0.5 ppm - corresponds to 1 drunk half-liter bottle of beer. The effect on perception is small, but it exists. It may be difficult to determine the distance to a moving object. Visual acuity also decreases, especially during twilight.

0.5-0.8 ppm - the level of intoxication corresponding to drunk 1 liter of beer. Spatial orientation is violated, difficulties may arise with the color identification of traffic signals. The ability to determine the distance to stationary objects is reduced. There is a dispersion of attention.

0.8-1.2 ppm - the value corresponds to 3 or more drunk bottles of beer. There is a sense of euphoria and limitless ability, which makes drivers more likely to violate traffic rules. It is this value that most often reveals the determination of the level of alcohol in the blood of drivers responsible for accidents.

1.2-1.5 ppm. There is a decrease in coordination of movements, a person reacts worse to pain and temperature changes. As a rule, thirst intensifies and weakness appears. In such a situation, every effort should be made to reduce the ethanol content. Drinking plenty of water and taking absorbent drugs will help.

2.5 or more ppm is an extremely dangerous concentration of alcohol in the blood. Clouding of consciousness, fainting is observed, epileptic seizures are possible.

Over 3.5 - severe alcohol poisoning. A person loses spatial and temporal orientation, does not respond to light and other external stimuli. The condition requires immediate medical attention. Such a ppm can result in severe poisoning and even death.

It must be taken into account that even an accurate calculation of the ppm value does not guarantee the correct result. The impact of alcohol on the human body can depend on many factors: gender, body weight, eating behavior, time of day, blood composition at the moment, and even race. The indicator is only a designation that cannot be taken as an absolute truth. The role is played not only by how much ethanol is contained in the blood, but also by the general condition of the body. The role of ppm in determining the state of the individual is slightly exaggerated. In some cases, even a negligible amount of alcohol can lead to catastrophic consequences. And knowing the exact amount of ethanol will not save you from tragedy.

What will help knowledge about ppm

Knowing this will help you avoid many problems. The harm done to the body depends precisely on the concentration of ethyl alcohol in the blood. The fact is that the main filter, the liver, is able to break down up to 12 mg of ethanol per hour to less harmful compounds. Everything that gets in excess of this dose goes straight into the blood, changing its composition and destroying cells.

12 mg of ethanol contains 1 bottle of mild lager beer. And since the concentration of alcohol gradually decreases, it is necessary to ensure that its approximate content in the blood does not exceed 0.5-0.7 ppm. Otherwise, serious damage will be done to the body.

Understanding all the negative aspects of drinking alcohol and knowing what is measured in ppm and how, allows you to keep addictions and weaknesses under control and not succumb to provocations. In this case, ppm is an identifier that makes it possible to soberly weigh all the consequences of even a dosed intake of ethyl alcohol into the blood.

Isn't this a divorce? Why sell online?

Yulek26 (Tver) 10 days ago

Sonya, what country do you live in? They sell on the Internet, because shops and pharmacies set their markup brutal. In addition, payment is only after receipt, that is, they first looked, checked and only then paid. And now everything is sold on the Internet - from clothes to TVs and furniture.

Editorial response 10 days ago

Sonya, hello. This drug for the treatment of alcohol dependence is indeed not sold through the pharmacy chain and retail stores in order to avoid overpricing. Currently, you can only order official website. Be healthy!

I'm sorry, I didn't notice at first the information about the cash on delivery. Then everything is in order for sure, if the payment is upon receipt.

I tried to give my husband a decoction of bay leaves to drink (she said that it was good for the heart), so after an hour he left with the men to drink. I no longer believe in these folk methods ...

; denoted by (‰ ); used to indicate the number of thousandths of something in general. The ppm sign is formed from the percent sign (%) by adding another "zero". The symbol can be entered on a Windows computer using Alt - 0 1 3 7: with Num Lock on, hold Alt and type 0137 on the numeric keypad.

1 ‰ = 1 ⁄ 1000 = 0,1 % = 0,001
100 ‰ = 10% = 0.1
300 ‰ = 300 ⁄ 1000 = 30% = 30 ⁄ 100 = 0,3
0.7‰ = 0.07% = 0.0007
0 ‰ = 0% = 0
1000‰ = 100% = 1

The value in ppm of the mass, expressed in kilograms, is equivalent to the mass in grams; from mass in tons - kilograms.

Application

There are some quantities (shares) traditionally measured in ppm.

Representing the rail as the hypotenuse of a right triangle, one of the legs of which has a length of 1000 meters and is parallel to the horizon, we will see that the second leg will be equal to the height to which the train will rise, having traveled a little more than 1 kilometer. The ratio of the second leg to the first in practice is often a very small value, so it is convenient to express it in thousandths. A slope of 8 ‰ means, for example, that after driving 1 kilometer, the train will rise to a height of 8 meters (the tangent of the ascent angle is 0.008, that is, the actual ascent angle is

Instruction

The term ppm means one thousandth of a substance present in another substance.

For example, the salinity of water equal to 30.0 0/00 (ppm) means that one liter of this water contains 30 g of various salts.
The average salinity of sea water is 35 0/00.

88.7% of chlorides are dissolved in sea water. Basically it is sodium chloride, that is, ordinary table salt or NaCl.

The main method for determining the salinity of sea water is the titration method.

To determine the salinity of the water in your aquarium with marine life, remove from it in a separate vessel, for example, 1 liter.

Add a certain amount of silver nitrate (AgNO3) to the water sample. Silver nitrate will combine with sodium chloride and precipitate.

Weigh the precipitated silver chloride and, given that the ratio of sodium chloride to other substances is always constant, calculate the salinity of the water.

However, it will be easier if you measure the salinity of the water with a hydrometer calibrated at room temperature.

In a woman, the same dose of alcohol as in, provided that they are equal in weight, will show a greater degree of intoxication on the device.

This is explained by the fact that the proportion of liquid, including, is 70% of the total mass, and in women only 60%.

Multiply the amount of drinks in grams by the drink and divide the result by your weight with a factor of 0.7 or 0.6.

For example: multiply 250 g of vodka by 0.4 (vodka strength 40%) and get 100 g.
Divide the result by your weight (you weigh 80 kg) and by K = 0.7.
100: (80x0.7) = 100: 56 = 1.79 0/00.

This result will be immediately after taking 250 g of vodka.

How are blood alcohol levels calculated?

Sometimes, after drinking alcohol, you may want to determine the degree of intoxication. Many people know that there are special tests and various devices for determining this condition, for this there is a special ppm scale. You can also find out the degree of intoxication on your own, objectively assessing your condition.

You will need

- breathalyzer;
- help of a sober person;
- pen and paper

Instruction

To find out exactly degree drunkenness, use a special device, such as a breathalyzer. Rinse your mouth, as the mouth should not contain. Take the device and draw full air. Exhale strongly by blowing into a special tube on the device. Assessing the concentration of alcohol vapor, the device will give a result.

Level 0.2 - 0.5. Follow some light source, in this state, the estimation of the distance from the subject to the subject will be violated. Try to estimate the distance ahead of moving cars, your estimate will be biased. Walk in a straight line, the gait in this state is quite clear, with only occasional stumbling. Try to evaluate your speech, for an easy degree drunkenness lively, meaningful, slightly confused speech with accelerated thinking is characteristic.

Level 0.5 - 0.8 ppm. Walk exactly along the given trajectory, your coordination should be somewhat disturbed. Pay attention to whether the perception of changing lighting and changing colors has become dull. Look at the color red and analyze your feelings, it works well at changing traffic lights. Stand with your eyes closed, with your legs outstretched, with your legs shifted, you will be slightly swayed.

Level 0.8 - 1.2 ppm. Take a walk and evaluate the perception of the environment, the angle of your vision becomes smaller, you begin to not notice the objects and people around you. Pay attention to how you react to the change of bright and dim light, the distance in such a situation should be distorted. Also, this condition is characterized by poor coordination and reaction time, relaxation, staggering gait and unsteadiness. Try to write some phrase, your underline will become more sweeping.

Level 1.2 - 2.4 ppm. Please note you may confuse items, greatly deteriorating. Coordination and reaction time deteriorate greatly, so try to squat down with your arms outstretched and your eyes closed, you will stagger sharply. Ask to evaluate your speech: in this state, blurring, monotony, meaningless and obsessive repetition of words, expressions, thoughts appear. Try to pronounce some tongue twister. Remember the state for yourself, you are already starting to stumble. This can be a good signal that it's time to stop.

PPM and Driver Condition

A person is considered if his blood contains no more than 0.3 ppm of alcohol. A concentration of 0.3-0.5 ppm gives a mild degree of intoxication. A person becomes less cautious, prone to recklessness and risk. He notices less moving light sources.

At 0.5-0.7 ppm of alcohol in the blood, the driver loses the ability to distinguish colors, correctly determine the distance, and feel the balance. He adapts worse to road situations, drives a car worse, evaluates his condition less critically. The reaction slows down.

A person is in a state of pronounced alcoholic intoxication when he has 0.7-1.3 ppm of alcohol in his blood. He no longer pays attention to traffic lights, belatedly notices objects on the roadway, slowing down cars in front, maneuvers of cars nearby. The reaction is significantly slowed down, attention is reduced, as is the ability to adequately assess the situation around.

When the indicator is 1.4-2.5 ppm, this is already a strong intoxication. Such a driver loses control over himself and over the vehicle, loses fear, becomes arrogant and careless. His speech becomes incoherent and his movements uncoordinated. The driver makes gross mistakes on the road - he confuses the brake and gas pedals, switches gears incorrectly, forgets about the turn signals.

3.0-5.0 ppm characterize severe poisoning. And at 5.0-7.0 ppm, a fatal outcome is likely.

Legislation

In most countries, drunk driving is punishable.

Until 2010, in Russia, the permissible level of alcohol in the blood was 0.3 ppm. In 2010, the so-called zero ppm was introduced, which caused outrage from many motorists. It was said that the use of kefir and kvass increases the amount of alcohol in the body, as well as the individual characteristics of people with an initially high alcohol content.

In the Russian Federation, on September 1, 2013, a law came into force, according to which the state of intoxication is the presence in the blood of a driver of absolute ethyl alcohol at a concentration of 0.16 mg or more per 1 liter of exhaled air, i.e. in excess of the possible error in measuring the concentration. For drunk driving, a fine and deprivation of a driver's license for a period of up to 2 years is provided.

The guidelines adopted by the Ministry of Health back in 1967 require that a person be considered sober if the alcohol content in one liter of his blood is not higher than 0.5 ppm. This applies to unconscious drivers and the dead, to whom it is impossible to apply the usual methods to determine the degree of intoxication and you have to take blood for analysis. These figures are guided by forensic medical experts.

Tula Regional Driving School

CHUDPO "Tula Regional Driving School"- This is one of the oldest organizations in Tula, which has been providing driving training in category "B" for more than 30 years. Initially, our driving school was part of the All-Russian Voluntary Society of Motorists, and in 1996 it became an independent organization that continues to train drivers at the highest level.

We have trained more than one generation of drivers, and our experience allows us to safely say that you will receive the maximum knowledge in the field of driving and traffic rules that meet all the latest innovations in legislation.

For all the time of its existence, our driving school has established itself as one of the best both in Tula and in the Tula region, since we have branches in Aleksin and Uzlovaya.

You can get the following types of auto-training from us:

by ear.

Training takes place in comfortable classrooms, equipped with all the necessary equipment and the necessary literature for complete and high-quality preparation for exams in the traffic police. Our fleet contains a large selection of cars, ranging from our own, Russian brands, ending with foreign cars. Therefore, you can choose the car that will be more convenient for you to learn to drive.

Here are some reasons why you should choose our driving school:

Huge experience of teaching staff.
Availability of necessary equipment and literature.
Provision of literature.
Affordable tuition fees.
Convenient location.
Large car park.
Installment payment.
Online training (theory) and passing the exam.

Also, for our students, we have the opportunity to take online theoretical preparation for exams.

The training program includes:

Theoretical course - where you will get acquainted with the rules of the road, the technical features of the operation and repair of a car, as well as first aid techniques. The cost of training is 14500 rubles.
A practical course, which is carried out in 2 stages: learning to drive in a closed area (autodrome) and driving in an urban environment, and includes 56 astronomical hours. The cost of the practical course is 10,000 rubles.

The signs of percent (%), ppm (‰), number (#) and paragraph (§) are used only with their numbers, from which they are separated by a non-breaking space. If it is necessary to use double signs of number and paragraph, then they are not separated from each other.

Examples. O relative air humidity 87%. AT In the Great Salt Lake, the salinity of the water reaches 250 ‰. W and 99.9% of voters voted for the candidate. W task number 5. Read § 11. Complete tasks number 4-8. Answers to questions can be found in §§ 6-9.

However in cases where the percent sign is used to abbreviate complex words formed with the help of a numeral and an adjective percentage, the percent sign is typed close to the number, that is, without a space.

For example, 20% sour cream(means twenty percent sour cream),
10% solution, 20% solution, but fat content of sour cream is 20%, solution concentration 10% etc.

Points are not used:

in headers and footers;
in headings;
in table rows;
in captions under figures, diagrams and diagrams.

Dots are not placed in the following common abbreviations:

designations of the system of measures (ha, mm, cm, kg, km, kW, etc.);
conventional abbreviations (used, cotton).

The point is put, if the words are not abbreviated according to generally accepted methods or there is no generally accepted method (electronic device, sq. m).

The point is put in abbreviations, etc., etc.

When separating a decimal fraction from a whole, a comma is placed in a fractional number, not a dot.

Hyphen it is used only in complex words like "after all", "little by little" and is not separated by spaces.

Dash used in all other cases and delimited by spaces on both sides

Middle dash, or minus sign (-). This sign never not used in literary text - exclusively in mathematical formulas as a minus sign. However, Word persistently pushes it as an autocorrect hyphen if the latter is surrounded by spaces. Word, apparently, knows that the hyphen is not surrounded by spaces, but the conclusions are a little different ... :

Long dash. It is the long dash, and only it, that is used as the usual "dash" - a punctuation mark. In all books you can meet exactly him. The task is complicated by the fact that there is no such key on the keyboard, and therefore many use the middle dash out of ignorance.

A dash should not start a line, so a non-breaking space must be inserted before the dash in dialogs.
