lung sounds

Lung sounds are the noises produced when air moves through the airways of the lungs during breathing. Normally, they are soft, gentle sounds called "vesicular" breaths, indicating healthy lung function. Abnormal sounds, like wheezes (high-pitched, whistling sounds), may suggest narrowing of airways, while crackles (small, popping sounds) can indicate fluid or inflammation. These sounds are important clues for healthcare providers to diagnose respiratory conditions such as asthma, pneumonia, or COPD. Listening to lung sounds helps evaluate lung health and guide appropriate treatment.
