What's the reason for wheezing when breathing in

summary

Inspiratory wheezing is more common in laryngeal edema, spasm or laryngeal cancer, tracheal foreign bodies, etc. It can also be seen in pertussis (pertussis is an acute respiratory infectious disease caused by pertussis bacilli). Its clinical feature is paroxysmal spasmodic cough accompanied by deep "chicken crow" like inspiratory roar. If it is not treated in time and effectively, the course of disease can be prolonged for several months. I'd like to talk about the reason why there is a sound when breathing in.

What's the reason for wheezing when breathing in

First, the disease is highly infectious and often causes epidemics. The younger the child, the heavier the illness, and the death of pneumonia and encephalopathy. In recent thirty years, the prevalence of pertussis has been greatly reduced, the incidence rate and mortality rate have been significantly reduced due to the extensive inoculation of vaccinations.

Second: wheezing is mainly due to extensive bronchospasm in the lung. When exhaling, the airflow passes through the narrow bronchioles and produces a pathological respiratory sound, which is most obvious when exhaling.

Third: wheezing is characterized by high pitch, musical sound like wire tremor, long duration, obvious on exhalation, and disappearance on inhalation. This kind of pathological breath sound can also appear when the ventilation is blocked by other diseases.

matters needing attention

Wheezing can also appear in the attack period of cardiogenic asthma, but this kind of wheezing exists both in the process of inspiration and expiration, and the extension of expiratory time is far less obvious than that of bronchial asthma.
