Wet rales

Introduction It is also called bubble sound due to the sound generated by the rupture of the bubble formed by the secretions in the respiratory tract such as exudate, sputum, blood, mucus and pus during inhalation. Or think that because the small bronchial wall is trapped due to the secretion of secretions, when inhaling, suddenly the popping sound generated by re-inflation is opened. The wet voice is an additional sound outside the breath sound. It is intermittent and short-lived. It often appears multiple times at a time. It is more obvious when inhaling or inhaling. Sometimes it occurs in the early part of exhalation. The part is relatively constant and the nature is not easy to change. Medium and small wet voices can exist at the same time, and can be alleviated or disappeared after coughing.

Cause

Localized wet snoring of the lungs, only suggesting local lesions at the site, such as pneumonia, tuberculosis or bronchiectasis, bilateral lung dampness, more common in heart failure caused by pulmonary blood stasis and bronchial pneumonia, such as two The lungs are covered with wet sputum, which is more common in acute pulmonary edema or severe bronchial pneumonia. It often appears in succession at one time, and is more obvious when inhaling or inhaling. Sometimes it occurs in the early stage of exhalation. The part is relatively constant, the nature is not easy to change, and the medium and small wet voices can exist at the same time. After coughing, it can be alleviated or disappear.

The characteristics of auscultation are intermittent and transient, and often appear multiple times at a time, which is more obvious when inhaling or inhaling, and sometimes in early exhalation. The part is relatively constant, the nature is not easy to change, and the medium and small wet voices can exist at the same time, and can be alleviated or disappeared after coughing. Large blisters, which occur in the trachea, main bronchus or cavity, occur mostly in the early stages of inhalation. Seen in bronchiectasis, pulmonary edema, tuberculosis or lung abscess, large blisters, occurring in the trachea, main bronchus or cavity, often appear in the early inhalation. Found in bronchiectasis, pulmonary edema, tuberculosis or lung abscess cavity.

Differential diagnosis

It should be differentiated from the abnormal sound of lung auscultation such as dry voice.

The dry sputum is a sound caused by turbulence when the air is inhaled or exhaled due to a narrow or incomplete obstruction of the trachea, bronchi, or bronchioles.
