Abnormal Lung Sounds. In this article learn about abnormal breath sounds including wheezing crackling rhonchi and stridor. They also can be a sign of lung disease like copd pneumonia. Wheezing sounds can usually be heard while exhaling the air during the breathing cycle wheezing sounds are caused by an obstruction to the airflow caused by the constriction of the lung airways. The most common causes of abnormal breath sounds are.
They can verify if it s the sound you thought it was or they can help you figure out which one it is. Furthermore the reproducibility of the lung sound parameters between days appears to be lower in asthmatic subjects than in controls probably due to variability of the generation and or transmission of lung sounds secondary to changes in the airway morphology. Wheezing sounds can usually be heard while exhaling the air during the breathing cycle wheezing sounds are caused by an obstruction to the airflow caused by the constriction of the lung airways. Qualitative differences in breath sounds are collectively called adventitious breath sounds. Wheezes and stridor tend to be fairly obvious when you hear them because they don t really sound like any of the others. Abnormal lung sounds such as stridor rhonchi wheezes and rales as well as characteristics such as pitch loudness and quality can give important clues as to the cause of respiratory symptoms.
Abnormal breath sounds are usually indicators of problems in the lungs or airways.
I really encourage you to ask your clinical instructor or nurse to listen with you to a patient s abnormal lung sounds. The three most common types of adventitious breath sounds are wheezes rhonchi and crackles. Wheezing is a high pitched whistling sound that is a common feature of abnormal respiratory conditions like asthma and chronic obstructive pulmonary diseases copd. These crunching sounds can sometimes mean you have a collapsed lung especially if you also have chest pain and shortness of breath. Wheezing sounds can usually be heard while exhaling the air during the breathing cycle wheezing sounds are caused by an obstruction to the airflow caused by the constriction of the lung airways. Abnormal breath sounds include sounds of differing intensity duration or quality when compared to those of the normal respiratory cycle.
