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. [2]
Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. [2] Bilateral crackles refers to the presence of crackles in both lungs. Basal crackles are crackles apparently originating in or near the base of the lung.
During auscultation, deep breaths are taken through the mouth and abnormal sounds listened for. [18] [19] Abnormal sounds include: Wheezes, describing a continuous musical sound on expiration or inspiration. A wheeze is the result of narrowed airways. Common causes include asthma and emphysema. [20]
When this occurs, the person experiences autophony, the hearing of self-generated sounds. [1] These sounds, such as one's own breathing, voice, and heartbeat, vibrate directly onto the ear drum and can create a "bucket on the head" effect, making it difficult for the patient to attend to environmental sounds.
Cheyne–Stokes respiration is an abnormal pattern of breathing characterized by progressively deeper, and sometimes faster, breathing followed by a gradual decrease that results in a temporary stop in breathing called an apnea. The pattern repeats, with each cycle usually taking 30 seconds to 2 minutes. [1]
Recently, she has had difficulty breathing unlike anything she remembers. At times, she feels tightness in her chest, and experiences a fit of coughing and wheezing.
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. [108]
