Exhaust gas poisoning car
The car is also the second wife, and the iron friend of man. She always listens, does not condemn, does not betray. It is more the prerogative of men than women to do car repairs or arrange "garage gatherings". For this reason, men are more often victims of car exhaust poisoning.
Therefore, for many car owners it will be useful to know the answers to the questions: under what conditions is possible intoxication with the products of combustion of gasoline, what are its signs, than to help the victim? Let's find out, and at the same time learn about the treatment and consequences of car exhaust poisoning.
How does carbon monoxide poisoning occur?
Exhaust fumes can cause serious harm to the body until death occurs when working with the car turned on in a closed garage or parking lot. Poisoning can happen in car service centers if safety rules are violated, in case of being in the cabin of an enclosed machine with malfunctioning ventilation, in apartments located above the parking lots.
When inhaling gasoline combustion products, acute intoxication occurs due to nitrogen oxides and carbon monoxide. Long-term exposure to exhaust gases at doses exceeding the maximum allowable levels, causes chronic poisoning by hydrocarbons, heavy metal compounds, leads to the formation of chronic diseases.
Clinical symptoms of poisoning
How to recognize poisoning? Signs of poisoning by exhaust gases are determined by the impact on the victim of various toxic substances.
Oxides of nitrogen
Nitric oxide (NO) - a gas without color and odor, interacting with oxygen in the atmospheric air, turns into NO2. Nitrogen dioxide settles in the lowlands and pits because of its gravity. Getting on a wet surface, NO2 turns into nitric acid and has a cauterizing effect on the mucous membrane of the mouth and respiratory tract. Contact with nitrogen dioxide causes the following symptoms:
- chest tightness;
- difficulty breathing;
- general weakness;
- hoarseness of voice.
For intoxication characterized by the presence of a latent period, when after the first manifestations of the symptoms almost completely disappear. In severe poisoning, after imaginary well-being, toxic laryngeal edema develops, lungs. It manifests itself:
- increasing dyspnea;
- bubbling noisy breathing;
- cough with separation of mucous sputum with an admixture of blood;
- blue lips, tips of the nose, ears, pale skin;
- normal or slightly elevated blood pressure.
The pulmonary edema caused by nitrogen dioxide is called blue because of the emerging characteristic color of the skin. This is important to see in connection with some features of his treatment.
Serious breathing disorders develop in the first 1-2 days of the disease.
Carbon monoxide is dangerous for the ability to interact with hemoglobin. The resulting links are very difficult to break. Carboxyhemoglobin can not displace carbon monoxide and capture oxygen, which leads to tissue hypoxia (oxygen starvation). Intoxication manifests similar symptoms both from nitrogen oxides, but is added:
- pulsation in the temples;
- darkening in the eyes;
There are 3 degrees of severity of poisoning. As the progression of intoxication comes, loss of consciousness and development of edema of the brain and lungs. The latter is called "gray" because of the corresponding coloration of the skin and mucous membranes.
Hydrocarbons (CxHx) have a toxic effect with incomplete combustion of fuel. Long-term contact with the concentration of hydrocarbons, slightly exceeding the permissible values, causes chronic intoxication.
When poisoning with exhaust gases, the symptoms of exposure to hydrocarbons are manifested:
- loss of consciousness.
The long-term consequences are associated with an increased risk of developing cancer.
Heavy metal compounds
To a greater extent, heavy metals are poisoned by lead. Long-term exposure to toxic compounds causes:
- double vision in the eyes;
- difficulty swallowing;
- stomach ache;
- memory impairment, attention (cognitive impairment).
Inhalation of heavy metal compounds causes toxic effects on the nervous and respiratory systems, blood, vessels.
The impact of all components of automobile exhausts on the human body in a complex intensifies each other's toxic effects.
Treatment for poisoning with exhaust gases
What should I do if I get poisoned by exhaust fumes? In connection with the high danger of pulmonary edema, we must immediately call an ambulance! Regardless of whether the victim has consciousness, you need to take the person to fresh air as soon as possible. The patient needs to provide peace and warmth to save tissue oxygen consumption. In the future, the arrived medical team conducts oxygen therapy. Through the catheters introduced into the nasal cavity, 50-60% oxygen is supplied.
If symptoms of pulmonary edema appear in the case of exhaust gas poisoning, first aid is reduced to the following.
- The patient is helped to take the position of a half sider.
- On the extremities, plaits are applied to reduce the flow of blood to the lungs.
- Injections of cardiac drugs (Strophantine-K, Cordiamin), diuretics (Lasix), antiedemics (Prednisolone).
- Enter 40% glucose, with the initial stage of poisoning used 10% calcium chloride.
Further car exhaust gas poisoning is continued in the hospital. Ineffectiveness of the performed measures is an indication for carrying out artificial ventilation of the lungs. In order to detoxify, hemosorption is carried out. In the absence of threat of pulmonary edema, saline solutions, glucose, with subsequent stimulation of urination are injected intravenously. To prevent infectious complications, antibiotics are prescribed.
Rehabilitation for severe poisoning with exhaust gases takes a long time and involves sanatorium treatment.
Consequences of poisoning with exhaust gases
The consequences of poison gas poisoning can be early and late. At the initial stages of the disease, there is a high probability of a fatal outcome from intoxication, and at later stages - from pulmonary edema, brain, and severe inflammation of the lungs.
The long-term consequences are reduced to the development of chronic respiratory diseases, oncological processes. The consequences can be so serious that the issue of disability can become.
Every year, the number of car owners increases, so knowledge about the dangers that the products of fuel combustion carry will not be superfluous. Exhaust gases contain many substances that affect the body in different ways. The course of the disease depends on many factors and in each case may take a different turn. It is important to remember the danger of complications of poisoning and the threat of death, so it is so important to observe precautions when working in the garage, do not be careless when the car's engine is turned on. And in case of suspicion of poisoning - it is timely to seek medical help.
