Sibilant

Wheezing is a term used to describe some of the abnormal wheezing sounds that can be heard when auscultating a patient's lungs with a stethoscope.

Such sounds usually indicate narrowing of the airways due to inflammation, swelling or spasm of the smooth muscles of the bronchi. Most often, wheezing occurs during exacerbations of bronchial asthma, chronic obstructive pulmonary disease, bronchitis and pneumonia.

The nature of wheezing can vary from high-frequency whistling to low-frequency wheezing. The intensity and timbre of sounds depend on the location, degree of narrowing of the airways and air flow speed.

Thus, the presence of wheezing or hissing breath upon auscultation indicates to the clinician that there is bronchial tree obstruction and may aid in the diagnosis and monitoring of related lung diseases.

Sibilant is a hissing or whistling sound. This term is applied to certain abnormal wheezes heard when a patient breathes through a stethoscope. Wheezing can occur due to narrowing of the airways, such as due to asthma, bronchitis or emphysema. They may also be a sign of pneumothorax or other pathologies of the lungs and respiratory tract. On auscultation, wheezing sounds have a high-frequency tone and resemble a whistling or hissing sound. Their presence requires further medical examination to clarify the diagnosis and prescribe adequate treatment.

A whistling sound (Sibilance) is a pathology when a patient inhales and exhales, which manifests itself in the form of certain sounds that are heard when listening under a stethoscope. It can have a different character and intensity, ranging from a slight hiss to a whistle similar to the sound of an airplane jet engine. In most cases, this condition indicates problems with the patient's respiratory tract. As a rule, such sounds do not appear at rest, but only when taking deep breaths and exhalations or when talking. It should be noted that the appearance of a whistling sound is not the only sign of a problem. The whistling sounds are usually accompanied by other symptoms such as difficulty breathing, fatigue, coughing and chest pain.

Wheezing can occur in patients with bronchitis, asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. It consists of alternating phases of inhalation and exhalation with the opening and closing of the glottis. This allows air to pass through the larynx. When whistling, a person's voice sounds very loud and sharp. The hissing sound is caused by a narrowing of the vocal cords or larynx as air tries to pass through the narrowed passage.

As with any health issue, the best solution is to see a doctor to determine the cause of the whistling sounds.
