Differences of pleural friction noise

The listening area for pleural friction noise is directly dependent on the location of the area of ​​its inflammation. As a rule, this type of noise can most often be found in the inferolateral areas of the chest, where active movement of the lungs takes place during breathing. In some cases, such noise is also recorded in the zone of the tops of the lungs, if they develop a severe tuberculous process, which then [...]

Pleural friction noise

Under normal physiological conditions, such pleural leaves as visceral and parietal are distinguished by a smooth surface and invariable "wet lubrication", which is used as a capillary layer of pleural fluid. In this case, the slip of the leaves of the pleura during breathing is carried out almost silently. A variety of pathological conditions of the pleura cause modification of the physical characteristics of the pleural sheets. This becomes the reason why the sheets start stronger [...]

Crepitus

Crepitatio (crepitatio) occurs in the alveoli, what is its main difference from wheezing. Some physicians incorrectly refer to crepitus, as crepitus or subcrepative wheezing. Crepitus is recorded as a light cod and is similar to the sound that is formed when rubbing a small group of hair directly over the ear. The key condition for the formation of crepitation is the accumulation in the alveolar lumen [...]

Nature of wet wheezing

Wet rales, taking into account the peculiarities of the pathological process in the lungs, are of such types as sonorous rales (they are also consonant) and non-vocal rales, that is, non-conservative. Sonic moist rales are recorded if there is a liquid secret in the bronchi, and the bronchi are surrounded by a thickened pulmonary tissue without air. Also, wheezing is found in the smooth cavities of the lungs, wrapped in a compressed pulmonary [...]

Wet rales

Wet rales occur due to accumulation in the lumen of the bronchi of a certain liquid secretion (such as sputum, edematous fluid, blood). When air flows through these secrets, air bubbles are formed there that have different diameters. Such bubbles, passing through a layer of liquid secretion of the lumen of the bronchus, where there is no liquid, then actively burst, which leads to the formation of a sound that can be compared [...]

Dry wheezing phases

Dry rales can be fixed at the stage of both inhalation and exhalation. Rattles of this type differ in such characteristics as loudness, height and timbre. Considering the pitch and timbre of the sound, dry rales can be divided into high, treble (ronchi sibilantes) (in other words, whistling), and low, bass (ronchi sonori), which can be called humming or humming rales. [...]

Dry rales

Wheezing (in Latin “ronchi”) is manifested due to the birth and development of the pathological process in the trachea, bronchi, or in the lung cavity formed. There are two types of wheezing: dry and wet. The origin of dry wheezing may be different. The main conditions for the appearance of dry wheezing include narrowing of the lumen of the bronchi. Moreover, such a narrowing may be total (with bronchial asthma), uneven [...]

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 such [...]
