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.

Crackles are more common during the inspiratory than the expiratory phase of breathing, but they may be heard during the expiratory phase. Crackles are often described as fine, medium, and coarse. They can also be characterized as to their timing: fine crackles are usually late-inspiratory, whereas coarse crackles are early inspiratory.
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
Another possible cause of chest pain that you can reproduce easily is costochondritis, which happens when the cartilage around your ribs becomes inflamed, the Mayo Clinic says. And it most often ...
Chest retractions may be observed in patients with asthma. During a chest retraction, the patient's skin appears to sink into the chest. During supra-sternal retractions, the skin of the neck appears to sink in as the accessory breathing muscles of the neck contract to aid with inspiration.
The classic symptoms are shortness of breath, wheezing, and chest tightness. [20] The wheezing is most often when breathing out. [ 109 ] While these are the primary symptoms of asthma, [ 110 ] some people present primarily with coughing , and in severe cases, air motion may be significantly impaired such that no wheezing is heard.

Asthma causes recurring episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or in the early morning. [4] Exercise-induced asthma is common in asthmatics, especially after participation in outdoor activities in cold weather.
