A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
The English bulldog, a typically brachycephalic dog breed, may have brachycephalic syndrome. A Peke-face Exotic shorthair.. Brachycephalic obstructive airway syndrome (BOAS), also known as brachycephalic airway obstructive syndrome (BAOS), brachycephalic airway syndrome (BAS), and brachycephalic syndrome (BS), [1] is a pathological condition affecting short nosed dogs and cats which can lead ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
Stridor (from Latin 'creaking/grating noise') is an extra-thoracic high-pitched breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree. It is different from a stertor, which is a noise originating in the pharynx. Stridor is a physical sign which is caused by a narrowed or obstructed airway.
[8] [9] With more severe contusions, breath sounds heard through a stethoscope may be decreased, or rales (an abnormal crackling sound in the chest accompanying breathing) may be present. [6] [10] People with severe contusions may have bronchorrhea (the production of watery sputum). [11] Wheezing and coughing are other signs. [12]
Stertor (from Latin stertere 'to snore') is a term first used in 1804 [2] to describe a noisy breathing sound, such as snoring. [3] [4] It is caused by partial obstruction of the upper airways, at the level of the nasopharynx or oropharynx. [1] It is distinguished from stridor by its pitch. [4]
There are several causes for a tracheal deviation, and the condition often presents along with difficulty breathing, coughing and abnormal breath sounds. The most common cause of tracheal deviation is a pneumothorax, which is a collection of air inside the chest, between the chest cavity and the lung. A pneumothorax can be spontaneous, caused ...
The resulting constriction and inflammation causes a narrowing of the airways and an increase in mucus production; this reduces the amount of oxygen that is available to the individual causing breathlessness, coughing and hypoxia. Bronchospasms are a serious potential complication of placing a breathing tube during general anesthesia.
