Wet cough

Depending on the above reasons, a non-productive (dry) and productive (wet) cough are distinguished. A productive (wet) cough is characterized by a separation of sputum. For some diseases, only an unproductive (dry) cough is typical, for others, especially inflammatory diseases of the respiratory system, is productive, usually replacing the unproductive.

Dry cough

Unproductive cough - dry cough, paroxysmal, debilitating and not bringing relief - is characteristic for the early stages of acute bronchitis, pneumonia (especially viral), lung infarction, the initial period of asthma attack, pleurisy and pulmonary embolism.

Causes of cough

The cough receptor agitation causes mechanical, chemical and thermal effects, as well as inflammatory changes, especially of the respiratory tract, including those developing under the influence of the above factors.

Cough

Cough (tussis) is an arbitrary or involuntary (reflex), jerky, forced, sonorous exhalation aimed at clearing the tracheobronchial tree from mucus, pus, blood and foreign bodies.
