hengitysäännettä

Hengitysäännettä refers to the sounds produced by breathing. These sounds are generated by the movement of air through the respiratory system, including the nose, pharynx, larynx, trachea, bronchi, and lungs. Under normal circumstances, breathing is relatively quiet. However, various conditions can alter the quality and intensity of these sounds, making them audible or even prominent.

Common causes of audible breathing sounds include congestion in the nasal passages, inflammation of the airways, or the presence of excess mucus. These can lead to sounds such as a stuffy nose, snoring, or a rattling sensation. More significant alterations in breathing sounds can indicate underlying medical issues. For example, a whistling or wheezing sound might suggest narrowed airways, often associated with asthma or other respiratory diseases. A harsh, crowing sound, known as stridor, can indicate a severe obstruction in the upper airway, requiring immediate medical attention. Crackling or bubbling sounds, often heard during auscultation with a stethoscope, can signify fluid in the lungs, as seen in pneumonia or pulmonary edema.

Healthcare professionals use the characteristics of breathing sounds to help diagnose respiratory conditions. While some breathing sounds are normal physiological occurrences, changes or the presence of unusual sounds warrant further investigation to ensure proper respiratory function and health.
