Wet rales

Introduction Wet squeak is the sound produced by the rupture of blisters formed by the secretion of gas in the respiratory tract such as exudate, sputum, blood, mucus and pus during inhalation, so it is also called blisters. 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. Wet voice is one of the important signs of auscultation in the lungs. 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. Divided into coarse, medium, fine wet voice and pronunciation. The distribution can be limited or the lungs are covered with wet sounds. More common in bronchitis, pneumonia, bronchiectasis, pulmonary congestion, pulmonary edema, pulmonary infarction, intermittent alveolar atelectasis and so on.

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; The lungs are covered with wet sputum, which is more common in acute pulmonary edema or severe bronchial pneumonia.

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.

Differential diagnosis

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