![]() Wheezes are also referred to as “Sibilant Wheezes”. There are minor differences that differentiate between the two. Wheezes and rales are terms that are often used interchangeably. Indication: These sounds indicate blockage of the airways due to any secretions or foreign bodies, etc. If a person coughs, then these rhonchi can be cleared over for some time too. They are named so because they closely appear to be like snoring and gurgling sounds. Now more prominently known as “Sonorous Wheezes”, the rhonchi are continuous, low-pitched sounds that are heard on both, inspiration and expiration of air. Indication: Crackles indicate the presence of fluid (such as pus or mucus) in the lungs, and may be associated with pulmonary edema, asthma, bronchitis, and congestive heart failure. Depending on the underlying condition, the crackles might be classified as coarse or fine-quality crackles. They resemble crackling, rattling or light bubbling type sounds, and are slow, high-pitched sounds. Previously recognized by the name of “Rales”, these abnormal breathing sounds are discontinuous types of sounds that are heard when a person inspires air. Here, we have enlisted some of the common abnormal breath sounds that are most commonly heard with a stethoscope and then treated accordingly by the doctor. Presence of Foreign Body in the AirwaysĮach one of the above mentioned causes gives rise to a different, characteristic abnormal breathing sound.Chronic Obstructive Pulmonary Disease (COPD).Causes of Abnormal Breath SoundsĪny pathology that interferes with the normal airways and their functions is said to give rise to abnormal breath sounds. When there is an underlying disease process such as inflammation, obstruction, infection, or the presence of fluid in the lungs, the airflow get turbulent and abnormal breath sounds are produced as a result.These sounds may or may not be heard by the person having the disease, requiring auscultation and other specialized tests can help in making a diagnosis. Thus, with each breath taken in and out, a gush of air moves through the respiratory tree without producing any sound. Normally, the airflow through the respiratory tree is laminar (streamlined) and encounters no obstruction. So, what are these abnormal breath sounds and where do they come from? Let us find more about them. These sounds or noises are barely audible unless otherwise heard over a stethoscope but sometimes healthy breath sounds can be audible too. However, not every abnormal breath sound is to be heard by the person experiencing it. Nothing? That means you are breathing normally.) ![]() (You may stop for 1 minute and hear yourself breathe. A person who is normal and healthy typically breathes without making any audible noise. This procedure is referred to as “Auscultation”.Īuscultation helps in finding out if there is anything wrong with your lungs and airways because any abnormal breathing sounds can be easily heard through a stethoscope.
