Respiratory sounds are noises produced during breathing, which can provide important information about lung health. These sounds can be classified into normal and abnormal types. Normal sounds include vesicular breath sounds, which are soft and low-pitched, while abnormal sounds, such as wheezes and crackles, may indicate underlying respiratory issues. Healthcare professionals often use a stethoscope to listen to these sounds during a physical examination. Changes in respiratory sounds can signal conditions like asthma, pneumonia, or chronic obstructive pulmonary disease (COPD). Identifying these sounds helps in diagnosing and managing respiratory diseases effectively.
