adventitious breath sounds medical definition

Several reviews related to automatic adventitious sounds analysis have been published. While computerised respiratory sound analysis, specifically for the detection or classification of adventitious sounds, has been the focus of an increasing number of studies recently, a standardised approach and comparison has not been well established.

However, the correct detection of these sounds relies on both, the presence of an “expert”, and their degree of expertise. An expert can perform auscultation using a stethoscope to detect abnormalities in sounds and use this information when making a diagnosis. The latter are referred to as adventitious sounds. Examples of this could be the absence of sounds or additive unusual ones. Airway abnormalities can cause breathing sounds to be abnormal. These include asthma, COPD, and pneumonia amongst others.

Air or fluid in or around the lungs (such as pneumonia, heart failure, and pleural effusion).Using a stethoscope, the health care provider may hear normal breathing sounds, decreased or absent breath sounds, and abnormal breath sounds. Normal lung sounds occur in all parts of the chest area, including above the collarbones and at the bottom of the rib cage. The lung sounds are best heard with a stethoscope.
