Amphora breath

Amphora breathing is fixed when there is a smooth-walled cavity with a diameter of more than 5-6 cm, interacting with a large bronchus. With a strong resonance, in addition to the basic low tone of laryngotracheal respiration, auxiliary high overtones appear that modify the tone of the basic tone of bronchial respiration. Noise of this type can be imitated by blowing a glass or clay bottle over the throat. It is for this reason that this modification of bronchial respiration is called amphoratic (from the Greek word “amphora”, that is, a clay vessel with a narrow neck).

The breathing of the metallic type differs in its characteristics from both the bronchial and the amphoraic types of breathing. Metal breathing is distinguished by a loud sound, as well as a very high timbre, which can be compared with the sound that occurs when the average strength of the impact on the metal. Metal breathing is heard with open pneumothorax, when the volume of air is located in the pleural cavity, interacting through the hole with external air.

Stenotic breathing represents a stronger laryngotracheal breathing. This type of breathing can be detected when a tumor reduces the diameter of the trachea or large bronchus. Stenotic respiration can be detected in the zones of listening to physiological bronchial respiration.

Vesiculobronchial or mixed-type breathing can be detected in case of focal pneumonia or infiltrative pulmonary tuberculosis. Also, such breathing can be detected in pneumosclerosis, when the sealing zones are located deep in the lung tissue and far enough from each other. Quite often, instead of weak bronchial breathing, you can listen to mixed breathing. In this situation, the inspiratory phase will have characteristics of vesicular respiration, and the expiratory phase will have bronchial respiration (in this case, we are talking about vesiculobronchial or bronchovesicular respiration).

As for the side respiratory noise, then it can be attributed to wheezing, crepitus and sounds of pleural friction.
