Laennec's sounds are a sound that is heard during auscultation of the lungs. It occurs as a result of air passing through the respiratory tract and can be caused by various lung diseases such as asthma, bronchitis, pneumonia and others. Laennec noise is usually described as a hoarse, rough, creaking sound, similar to a cracking or crunching sound. It can be heard on both inhalation and exhalation, and is often accompanied by other sounds such as crepitus and wheezing.
Laennec noise is often diagnosed in patients with acute respiratory infection, especially in children. However, it can also be associated with chronic lung diseases such as emphysema or bronchiectasis. In such cases, Laennec noise may be constant or intermittent and accompanied by other symptoms such as cough, shortness of breath and chest pain.
Auscultation of the lungs is used to diagnose Laennec murmur. The doctor listens to the patient's lungs and determines the presence or absence of this sound. If a Laennec murmur is present, it may indicate the presence of a serious lung disease and requires further evaluation and treatment.
Treatment for Laennec noises depends on the cause of their occurrence. If it is associated with an acute respiratory illness, then treatment with antibiotics and other drugs to control the infection is usually sufficient. In the case of chronic lung diseases, treatment may include breathing therapy, inhalation and other methods.
It is important to remember that Laennec noise is only one symptom of lung disease. If you hear this sound, contact your doctor for advice and diagnosis.
