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.
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.

Patients often experience wheezing, shortness of breath, and a chronic cough. A wheeze is a coarse, whistling sound in the airways during breathing. Patients can have worsening of their symptoms called exacerbations. Exacerbations may include increased mucus production and reduced exercise tolerance. [11]
Crackles are the clicking, rattling, or crackling noises that may be made by one or both lungs of a human with a respiratory disease during inhalation, and occasionally during exhalation. They are usually heard only with a stethoscope ("on auscultation"). Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. [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.
With emphysema the shortness of breath due to effective bronchoconstriction from excessive very thick mucus blockage (it is so thick that great difficulty is encountered in expelling it resulting in near exhaustion at times) can bring on panic attacks unless the individual expects this and has effectively learned pursed lip breathing to more quickly transfer oxygen to the blood via the damaged ...
Officials at the state Department of Juvenile Justice did not respond to questions about YSI. A department spokeswoman, Meghan Speakes Collins, pointed to overall improvements the state has made in its contract monitoring process, such as conducting more interviews with randomly selected youth to get a better understanding of conditions and analyzing problematic trends such as high staff turnover.
Whistling can be used to control trained animals such as dogs. A shepherd's whistle is often used instead. Whistling has long been used as a specialized communication between laborers. For example, whistling in theatre, particularly on-stage, is used by flymen (members of a fly crew) to cue the lowering or raising of a batten pipe or flat. This ...
