What is the smoke poisoning?
Risk of poisoning occurs when a fire is something smoldering and smoke. The structure of modern building materials is quite a lot of cyanide, so a fire is always a danger of cyanide poisoning. Cyanic acid (hydrogen cyanide) and its salts are highly toxic, danger to life may be even a small amount. The second is a poisonous substance is carbon monoxide, which is released by partial combustion of certain materials. In addition to these substances, there are many acids that damage the lining of the respiratory tract and enter the lungs.
Symptoms of smoke poisoning
Causes of smoke poisoning
When a person inhales the smoke, the two main poison directly from the lungs enter the bloodstream: carbon monoxide and cyanide. Adverse effects of these substances on the human body are approximately the same.
Monoxide carbon blocks blood pigment (hemoglobin) and disrupts the transport of oxygen from the lungs to various organs; cyanide in the body violates the vital process of cellular respiration and energy metabolism of cells. In addition, provision is violated, and cells with oxygen (usually oxygen in the cells come from blood). When a person inhales the smoke, the bronchioles in the human body become narrower. The result is a lot of fluid in the lungs.
Treatment of smoke poisoning
First you need to find out whether the victim is breathing, you should check the heartbeat. If the heart and circulatory system is functioning properly, you must provide the patient with oxygen, this in ambulance available ventilators. In addition, applying artificial respiration, you can install so-called hyperventilation mode, ie lodge in the lungs the patient more oxygen than he could breathe under normal breathing, so the blood gets plenty of oxygen. If the patient had been poisoned with cyanide, then it is assigned an additional medication.
A man's life often depends on whether he was given first aid. The main task of a person who provides first aid for poisoning with smoke - support the respiratory functions and blood of the victim. First of all, make sure not clogged airways something (eg, vomit). Then you must determine that the victim's heart beats for that, you have to feel the pulse of the carotid artery. If the pulse is not palpable, you should immediately do chest compressions and artificial respiration.
If there was carbon monoxide poisoning, its symptoms may appear after several hours. The first signs of such poisoning - dizziness, dyspnea, and headache. In any case, carbon monoxide poisoning should contact the nearest hospital.
The main task of the doctor: to provide the patient with oxygen. In severe cases, treatment of patients spends in hospital special compartments in the cell of high pressure oxygen (a so-called hyperbaric oxygen therapy).
Course of the disease
Smoke poisoning is very fast and is often life-threatening. However, if it is possible to maintain vital body functions during the first hours after exposure, then there is no danger to life.
Symptoms of smoke poisoning may occur within a few hours, when already there was a danger to the life of the victim.
The effectiveness of rescue breathing and chest compressions can be identified by the victim complexion. If these steps are successful, then bluish face gradually disappears, and the patient's skin becomes normal color. The skin of a man who was poisoned by the smoke can be a normal color, although, perhaps, a man almost choked.
