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.

Coarse crackles are somewhat louder, lower in pitch, and last longer than fine crackles. Their presence usually indicates an airway disease, such as bronchiectasis . They can also be described as unilateral or bilateral, [ 9 ] as well as dry or moist/wet.
Treatment depends on how severe the patient's condition is and the cause of the obstruction. If the patient is choking on a foreign body, the Heimlich maneuver can be used. More invasive methods, such as intubation, may be necessary to secure the airway. In severe cases, intubation may be difficult and a cricothyrotomy or tracheostomy may be ...
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
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.
Normally, the sound of the patient's voice becomes less distinct as the auscultation moves peripherally; bronchophony is the phenomenon of the patient's voice remaining loud at the periphery of the lungs or sounding louder than usual over a distinct area of consolidation, such as in pneumonia.
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]
