Asthma is caused by a certain reason acting on the larynx, causing stenosis, narrowing the air intake channel, and reducing the lung ventilation. Let's talk about the differences you follow.

Is asthma asthma?

Wheezing when combined with respiratory tract infection, due to bronchiolar mucosal congestion and edema, sputum obstruction and bronchial stenosis, can produce asthma (wheezing) symptoms. Wheezing occurred in the throat during breathing and wheezing occurred in the lung during auscultation. This type of asthma is called asthmatic bronchitis clinically; But its attack condition is not like the typical bronchial asthma.

Asthma is a kind of allergic disease. Before the attack, there are aural symptoms, such as sneezing, runny nose, cough and chest tightness. It is generally due to the stimulation of smoke, foreign bodies and cold air, which makes the trachea and bronchus contract violently and secrete a large number of secretions, resulting in shortness of breath. A large number of secretions block the trachea and bronchus, making it difficult to breathe, with wheezing, There may even be cyanosis and shock, which need to be relieved with drugs.

Asthma is a symptom description, is due to a long period of severe cough, or refers to severe exercise, leading to alveolar and bronchospasm, lung blood oxygen exchange function is reduced, resulting in a compensatory performance, the general onset is relatively slow, relieve faster after rest, long-term occurrence may be the precursor of emphysema.

matters needing attention

When bronchial asthma attacks, there may be extensive wheezing sound in both lungs during the expiratory period, and sometimes it can be heard only in both ears. However, when asthma attacks seriously and dyspnea intensifies, it is difficult to hear wheezing sound due to excessive fatigue, weakness and inability to exhale. So we can't judge the disease according to the absence of wheezing sound.
