Is there blister sound in left lung breathing?

summary

When auscultating breath sounds, the air can pass through the secreting trachea. At this time, when the air passes through the swollen or spasmodic bronchus, doctors can hear some additional breath murmurs, which are also called rales. According to some characteristics and properties of rales, they can be divided into dry rales and wet rales. Through such diagnosis, further diagnosis can be made, Plus some other examination methods, and then symptomatic treatment. Let's share my experience with you.

Is there blister sound in left lung breathing?

Dry rales are caused by tracheobronchial stenosis or partial obstruction, and turbulence when the air is inhaled or exhaled. They are more common in bronchial mucosa congestion and edema, secretion thickening, bronchial smooth muscle spasm, or intraluminal tumor or foreign body obstruction caused by respiratory tract inflammation. When dry rales occur in larger bronchi, they are called snoring, characterized by low pitch and high loudness; When it occurs in small bronchi, it is called "flute sound" or "flying arrow sound", which is characterized by sharp, short and high pitch; If the "flute sound" can be heard all over the lung field, it can also be called "wheezing sound".

Dry rales can be heard when exhaling or inhaling, but it is more obvious when exhaling. Its tone and position are changeable and uncertain, that is, it increases or decreases significantly in a short period of time, which is mostly caused by bronchitis. If it is wheezing, it is mostly caused by bronchial asthma or asthmatic bronchitis. It is common in bronchial asthma, chronic bronchitis and cardiogenic pulmonary edema; Local dry rales are common in endobronchial tuberculosis or tumor.

Moist rale (also known as blister sound), when breathing, air flow through the trachea or bronchus containing thin secretions, so that secretions form blisters and burst rapidly. It is the sound produced by the gas passing through the thin secretion in the respiratory tract when inhaled. According to the size of the respiratory tract cavity and the amount of secretion, the blister sound can be divided into large, medium and small (or thick, medium and fine moist rales), which are produced in the large, medium and small bronchi respectively.

matters needing attention

Moist rales can be diffused in the whole lung, or limited to a certain part of the lung. They can be heard when breathing in and out, but more obvious when breathing in deeply. Clinical common in bronchitis, pneumonia, tuberculosis, pulmonary congestion, pulmonary edema and bronchiectasis.
