low breath sounds
Introduction
Introduction Low breath sounds are more common in acute tracheal-bronchitis. Acute tracheal-bronchitis is a common disease that causes acute inflammation of the tracheal-bronchial mucosa caused by a variety of causes. The prognosis is good, and the mucosal structure can be completely restored to normal after treatment. The incidence rate is higher in winter.
Cause
Cause
Acute inflammation of the tracheal-bronchial mucosa caused by viral and bacterial infections, physical and chemical factor stimuli or allergic reactions. The main clinical symptoms are cough and phlegm, and severe asthma can occur. The disease is a common and frequently-occurring disease of the respiratory system and can occur at any age without significant gender differences. Often caused by the cold season in winter and spring or induced by climate change.

1. The onset is more urgent, mild chills, fever, headache and body aches.
2. Cough. Start with mild irritation, a little mucus, followed by cough mucus or mucopurulent sputum, sometimes with bloody spasms.
3. Those who are seriously ill have a cough all day, or have anxious. Cough often lasts for several weeks.
4. The lungs have low breath sounds and dry rales scattered in the low-pitched sound; when there are many and thin, wet rales appear, the parts and time are not constant, and they can disappear after coughing.
Diagnosis
Differential diagnosis
It is necessary to distinguish from the following symptoms: tube-like breath sounds: tube-like breath sounds, also known as abnormal bronchial breath sounds, refer to bronchial breath sounds heard in the normal alveolar breath sound distribution area. Attenuated breath sounds: The breath sounds are mainly alveolar breath sounds, and the weakening or disappearance of alveolar breath sounds is associated with a decrease in air flow in the alveoli or a decrease in air flow velocity into the lungs and a disturbance in respiratory sound transmission. It can occur locally, unilaterally or in both lungs.
