Phlegm sound

Introduction Generally, the snoring sound is generated by the vibration of the more viscous secretion in the main airway. It is a special kind of wet rales. Both inhalation and exhalation can be heard, but inhalation can be transmitted to both lungs. So it can be heard in both lungs (not really caused by the lungs), and once the secretions are removed or sucked out, the snoring sounds weakened or disappeared. Divided into coarse, medium, fine wet rales and pronunciation. The distribution can be limited or the two lungs are covered with wet rales. More common in bronchitis, pneumonia, bronchiectasis, pulmonary congestion, pulmonary edema, pulmonary infarction and so on.

Cause

When breathing, when the airflow passes through the trachea or bronchus containing thin secretions, the secretions form blisters and rapidly blast, resulting in a large blisters sound, which is lowered by sound. The formation mechanism is because when the gas passes through the respiratory tract, if there is secretion (such as sputum, exudate, blood, mucus, pus, etc.) in the respiratory tract, blisters will form, and the vesicle will be broken.

1, coarse wet voice: occurs in the trachea, the main bronchus or cavity parts, mostly in the early inhalation.

2, the wet voice: occurs in the middle of the bronchi, and more often appears in the late inhalation.

3, fine wet voice: occurs in the small bronchi, more in the late inhalation.

4, pronunciation: very fine and uniform wet rales, more at the end of inhalation to hear.

Differential diagnosis

The differential diagnosis of humming sound:

1, coarse wet rales: also known as large blisters. Occurs in the trachea, bronchus or cavity, and occurs mostly in the early stage of inspiratory phase. Patients who are comatose or sudden death are unable to discharge respiratory secretions. They can be heard at the trachea and have a rough wet rake. Sometimes they can be heard without a stethoscope.

2, the wet rales: also known as the water bubble. Occurs in moderately sized bronchi, mostly in the middle of inhalation. Found in bronchitis, bronchial pneumonia and so on.

3, fine wet rales: also known as small blisters. Occurred in the small bronchi, mostly in the late inhalation. Common in bronchiolitis, bronchial pneumonia, pulmonary congestion and pulmonary infarction.
