Strength and timbre of bronchial respiration

In the pathological form of bronchial respiration, taking into account such features as the type of compaction of the lung tissue, the volume of the compacted region and the area of ​​its location in the lungs is not only heterogeneous force, but also the characteristic timbre of the sound.

If there is a massive area of ​​compacted lung tissue, which is located superficially, then lung bronchial respiration can be detected in the lung. Breath of this type appears as if directly under the ear. The timbre of such a breath, in the described situation, is often higher.

This type of breathing is monitored at the second stage of lobar pneumonia, when the lesion spreads to a whole lobe of the lung. If the lung segment or its deeper elements are compacted, then bronchial respiration, which is carried out directly on the surface of the chest wall, will sound quieter, and the respiration timbre will be much lower.

Such breathing is also fixed in case of focal pneumonia, when several foci are too close to each other or merge altogether, thus forming an extensive sealing zone (confluent pneumonia).

The most quiet bronchial respiration of a rather low timbre is recorded in patients suffering from compression lung atelectasis. Such breathing is like a weak "echo" sound, which, as if from afar, reaches the ear of the doctor.

Pathological bronchial respiration is also heard, and then, when an abscess or cavity appears in the cavity of the lung, free from the contents and interacting with the bronchi. At the same time, the compaction of the lung tissue in the area around the cavity helps to more effectively conduct the sound waves of laryngotracheal respiration, which also provides further compaction of the lung tissue around the cavity. In addition, it contributes to the amplification of sound waves in the cavity itself, which resembles a resonator effect, due to which air turbulence in the cavity is formed at the moment when the sound wave moves from the narrow plane of the bronchi during the inhalation stage.
