Breath Sounds A Guide to Auscultating Breath SoundsWheezing: Wheezing is a highpitched, whistling sound that is a common feature of abnormal respiratory conditions like asthma and chronic obstructive pulmonary diseases (COPD). Wheezing sounds can usually be heard while exhaling the air during the breathing cycle.

Adventitious breath sounds are abnormal sounds that are heard over a patient's lungs and airways. These sounds include abnormal sounds such as fine and coarse crackles (crackles are also called rales), wheezes (sometimes called rhonchi), pleural rubs and stridor. Abnormal breath sounds can indicate a lung problem, such as an obstruction, inflammation, or infection. Learn about breath sounds and what they may mean.

The lung sounds are best heard with a stethoscope. This is called auscultation. Normal lung sounds occur in all parts of the chest area, including above the collarbones and at the bottom of the rib cage. Using a stethoscope, the doctor may hear normal breathing sounds, decreased or absent breath sounds, and abnormal breath sounds. abnormal lung sounds and pathophysiology Abnormal Breathing Sounds Types and Causes Posted by Dr. Chris Abnormal breathing sounds differs in quality from the normal hollow, rustling sound that is heard as air passes through the large airways like the pharynx, larynx and trachea (bronchial breathing) and resonates in the bronchial tree and lungs (vesicular breathing).

I really encourage you to ask your clinical instructor or nurse to listen with you to a patients abnormal lung sounds.

It is important to distinguish normal respiratory sounds from abnormal ones for example crackles Abnormal breath sounds include: the absence of sound andor; the presence of normal sounds in areas where they are normally not heard. For example, bronchial (loud& tubular) breath sounds are abnormal in peripheral areas where only vesicular (soft& rustling) sounds should be heard.
