What disease is bronchial breath sounds

What is the definition of bronchial breath sounds? I believe everyone has some questions about this question but cannot get a satisfactory answer. Don't worry, you can find a satisfactory answer to the definition of bronchial breathing in the text listed below. The definition of bronchial breath sounds is easy for us to understand. The simple and clear words can make you master it easily without being troubled.

Breath sounds When a normal person breathes, the air flow passes through the respiratory tract and alveoli, generating turbulence that causes vibration and makes sounds. The sounds that are transmitted to the body surface through the lung tissue and chest wall are called breath sounds. Breath sounds can be divided into three types according to their intensity, pitch, nature, duration and auscultation site.

Bronchial breath sounds are the sounds produced by turbulence of airflow in the glottis and trachea during breathing, similar to the "ha" sound made when the tongue is raised and exhaled through the mouth. Inhalation is an active movement, the glottis widens, and the air flows through faster; exhalation is a passive movement, the glottis narrows, and the air flows through slower, so exhalation is longer than inhalation, the pitch is higher, and the sound is stronger.

In normal people, bronchial breath sounds can be heard in the throat, manubrium, suprasternal fossa, near the 6th to 7th cervical vertebrae and the 1st to 2nd thoracic vertebrae on the back. The closer to the trachea area, the stronger the sound and the lower the pitch.

If bronchial breath sounds are heard in the area of ​​normal alveolar breath sounds, they are abnormal bronchial breath sounds.

1. Such as lobar pneumonia 2. Large cavities in the lungs: such as lung abscess or cavitary tuberculosis 3. Compressive atelectasis.

If bronchial breath sounds are heard in the area of ​​normal alveolar breath sounds, they are abnormal bronchial breath sounds, or tube-like breath sounds.

It may be due to lung tissue consolidation, which causes bronchial breath sounds to pass through the denser part of the lung consolidation and reach the body surface, making them easy to hear. The location, range and strength of bronchial breath sounds are related to the location, size and depth of the lesions. The larger and shallower the range of the change, the stronger the sound, and vice versa. It is common in the consolidation stage of lobar pneumonia, with strong, high-pitched bronchial breath sounds close to the ears.

In short, this is the definition of bronchial breath sounds. Bronchial breath sounds are a part of our body and an indispensable and extremely important part of our life. Understanding it, knowing it, and cherishing it are exactly what we should do after reading the above answers despite our shallow definition of it.
