Cough - a complex reflex act that occurs during stimulation of receptors of the larynx, trachea, large bronchi and pleura. When coughing reduction of respiratory muscles provides a powerful sharp emission of air.
For reasons of occurrence of a cough is divided into physiological and pathological. Physiological cough helps to remove all foreign bodies from the airway. The main features are the physiological cough frequency and brevity. Pathological cough accompanied by a variety of respiratory diseases. Dry cough is called a cough without sputum. This type of cough can occur in many diseases of the respiratory tract. Dry cough can be acute (less than two weeks), prolonged (two to four weeks), subacute (one to two months), or chronic (over two months).
Causes of dry cough
Cough - an important and informative indicator of trouble in the body. The most common causes of dry cough include:

- angioedema, asthma;
- side effects of certain medicines;
- gastroezofageolny reflux;
- postnasal drainage;
- a collapsed lung;
- heart failure;
- aortic aneurysm;
- systemic lupus erythematosus;
- postnasal drainage;
- whooping cough;
- tracheitis, laryngitis, bronchitis;
- long smoking history;
- inhalation of irritating chemicals.
Voiced cough indicates viral diseases. Deaf dry cough - the first sign of tuberculosis and lung tumors. Whooping cough can be accompanied by hysterical dry cough. During the treatment, a dry cough usually becomes wet.
Cough may cause injury of airway obstruction, inflammation. This type of cough can be triggered by croup, empyema, tuberculosis, Legionnaires' disease, whooping cough.
Pathological cough may be accompanied by violations of the chair, bad breath, wanton loss of kilos, lack of appetite, bleeding gums, a hoarse voice, the appearance of shortness of breath, vomiting, nausea. Dry cough can be dangerous for the patient's life if it is accompanied by a constrained speech, frequent urination, difficulty breathing, increased heart rate, swelling of the extremities.
Methods of treatment of dry cough
If cough persists for a long time, it is necessary to identify its causes and eliminate them. Treatment of dry cough can be done in isolation, if the source was not found. When coughing, be sure to monitor the moisture of the air, drink plenty of fluids during the day and avoid contact with irritants (aerosols, detergents and caustic vapors). Remove the cough helps the tablet or mint candy.
The strategy of treatment of dry cough should be aimed at, to translate it into the wet form. Medicines are non-narcotic cough and drugs. It refers to drugs codeine. Codeine is found in many cough medicines. This substance has an impact on the whole brain, which explains numerous side effects associated with its use. It does not have a narcotic effect dextromethorphan. This material reduces the excitability of the cough center. It does not cause drowsiness, dependence and analgesia.
There are also remedies for dry cough, do not suppress certain brain centers, and blocking receptors in the bronchi. These include syrup, "Dr. Tice," "Fervex", "Terpikond", "Codelac broncho".
Antihistamines should be used when an allergic reaction has occurred bronchoconstriction.
To convert non-productive cough in the wet it is advisable to use a mucolytic and expectorant. Mucolytic means dry cough reduce sputum viscosity, liquefied it. Expectorants help to strengthen the mucous secretion of the bronchi (Atseltsistein, Ambroxol, ACC).
Inhalation of dry cough
If the cough persists after use of medicines, the state will help to significantly alleviate alkaline inhalation. Sputum usually begins after only five or six treatments inhalation of dry cough. During inhalation alkali enters the respiratory tract and liquefy sputum without damaging the mucosa and thus without causing an allergic reaction.
Nebulizer - inhaler device is designed for inhalation treatments at home. Nebulizer needs placed in solution in a finely divided substance. In this state, any means is very easy to pass through the nasal passages and into the bronchi.
Soda in contact with water breaks down into water, carbon dioxide and alkali, so it can be successfully used for alkaline inhalations when coughing. To do this, you need a glass of warm water to dissolve the three teaspoons of baking soda. The resulting solution should be placed in a nebulizer and breath max 8-15 minutes.
For inhalation of dry cough can also use a solution of ambroxol. For this purpose it is necessary to pre-mix with saline.
When you cough very helpful breathing vapors of mineral water. Any mineral water should be poured into a container and let stand for about an hour to her that all the carbon dioxide released. Breathe mineral water is recommended no more than three or four minutes.
