Ppm is a unit for determining the amount of alcohol in the blood. One unit per mille is one thousandth of a substance, a tenth of a percent liquid. There is a significant difference between the body of a man and a woman in identifying this indicator. Ppm - how much? This question interests many.
Designation and calculation
The ppm sign is as follows - ‰. It is often confused with a percent sign, which is a mistake.
- 1 ‰ = 0.1% = 1/1000 = 0.001.
- 100 ‰ = 10% = 0.1.
- 200 ‰ = 20% = 200/1000 = 0.2.
30 minutes after consumption, the maximum concentration of alcohol can be detected in the human body.
Promille is an indicator that provides information on:
- the alcohol content at a particular point in time;
- the volume of the drink of various kinds;
- the time it takes for alcohol to be eliminated from the body.
The result will depend on the following parameters:
- weight, gender, age of the person;
- percent fluid in relation to the mass of the human body;
- volume of alcohol that has been taken.
So ppm is how much?
Stages of intoxication
The stages of intoxication vary depending on the alcohol consumed. The first is characterized only by light intoxication, moderate severity will be observed in the second, a severe degree appears in the third stage of intoxication. The last stage is life-threatening, as a coma and even death can develop.
The lethal dose will be for humans:
- 4-8 gr. ethyl alcohol per 1 kg of weight for an adult;
- 3 gr. per 1 kg of weight of adolescents, patients and the elderly.
Next, let's talk about the percentage of ethanol in the blood at each stage:
- up to 0.3% - the effect of alcohol is absent;
- 0.3-0.5% - the effect is rather weak;
- 0.5-1.5% - means a mild degree;
- 1.5-2.5% - medium degree;
- 2.5-3% - a strong stage;
- 3-5% - a severe stage in which coma and even death can occur;
- 5-6% - means a lethal dose.
Ppm which is allowed
What is allowed ppm? This is the amount at which it is still permissible to drive.
With what amount of drink will the movement be safe? The behavior and reaction of the driver will differ depending on the ppm:
- 0.1-0.6 ppm. The source of moving light is perceived vaguely. Bad assessment of the situation. The driving style becomes risky, the speed often exceeds the permissible norms, the driver can harm others.
- 0.6-0.9 ppm. The distance estimate is incorrect, an imbalance occurs, the assessment of the situation is difficult. The driver does not adequately evaluate the lighting, distance, signal of other cars and traffic lights.
- 0.9-1.3 ppm. Alcohol is relaxing. There is a decrease in the angle of view, with a weak and incorrect perception of the surrounding reality. The concentration of attention is completely absent, a high degree of intoxication makes the driver dangerous to others and to himself as well.
- 1.3-2.5 ppm. Maintaining consciousness is difficult; there is no question of driving a car. Impaired vision, reaction, orientation in space.
The allowed ppm is 0.1 units or less.
Signs of intoxication
A person is considered drunk if there are a number of signs. It:
- strong smell of alcohol from the mouth;
- unstable posture, pronounced trembling of the fingers;
- speech impairment, behavior that does not match the environment;
- sudden changes in skin color (redness, blanching);
- sharp incorrect movements, inappropriate behavior.
How to determine the ppm acceptable for drinking?
The ratio of the number of ppm in the blood and signs of behavior at a certain stage of intoxication will be as follows.
At a level of alcohol of 0.010-0.030, normal behavior will be normal, with hidden violations that can only be determined by special means, this stage of intoxication is considered easy.
At a level of alcohol of 0.031-0.060, behavior is characterized by mild euphoria, talkativeness, relaxation, a decrease in the level of restraint with a decrease in concentration, mild intoxication becomes average.
At an alcohol level of 0.061-0.1, the behavior is characterized by extroversion, dulling of all sensations, strong disinhibition, impaired perception and reasoning, a poor pupil reaction to light appears, this is still an average degree of intoxication.
At an alcohol level of 0.11-0.2, the behavior is characterized by fury, anger, strong changes in emotions, expressiveness, reflexes, articulate speech, behavior control, motor skills, intoxication are most likely to occur, and the degree of intoxication is strong.
At a level of alcohol of 0.21-0.30, the behavior is characterized by stupor, a possible loss of consciousness, a weakening of all sensations, memory, consciousness, motor skills are disturbed, the stage of intoxication is very strong, poisoning sets in.
At the level of 0.31-0.40, the behavior is characterized by loss of consciousness, severe depression of the central nervous system, death can occur, control, palpitations, breathing, balance may be disturbed, intoxication with severe intoxication occurs.
At the level of 0.41-0.51, the behavior is characterized by loss of consciousness, a fatal outcome is possible , control is lost, breathing, palpitations are disturbed, nystagmus appears, intoxication is severe and dangerous to human life.
At a level of more than 0.51, severe poisoning of the body with a fatal outcome occurs.
Lethal dose: is there a definite answer?
Promille is an indicator that can help determine the lethal dose.
In each individual case, its indicators differ. Even a doctor is difficult to clearly determine. So how much alcohol can you drink, and how much will already be dangerous to humans?
In figures, we have already considered these indicators. 6-8 ppm will be a lethal dose for an adult, 2.5 ppm means intoxication. But it’s more convenient for an average person to count in liters.
So, the norm of ppm is known.
If you drink one bottle of vodka for an adult, then you get just 2.5 ppm. And if you take three bottles with a volume of half a liter, then this will be a lethal dose. But it should be borne in mind that a person should drink this alcohol in about an hour. But if you stretch the alcohol for a long time, especially with a snack and vigorous movements, then there will be no death, but only severe intoxication.
Wine and beer have a weaker alcohol concentration. To get a lethal dose, you need to drink a lot. With a large amount of drunk, a protective reaction of the body occurs in the form of vomiting, so part of the alcohol is eliminated from the body. The lethal dose directly depends on weight, age, gender and chronic diseases.
Thus, ppm is a unit of measurement of blood alcohol content, a very informative indicator.
