respiratory sounds

Respiratory sounds are the noises made during breathing, heard through a stethoscope. Normal sounds include bronchial sounds from the trachea and vesicular sounds from the lungs' air sacs. Abnormal sounds, such as wheezes, indicate airway narrowing, while crackles suggest fluid in the lungs. These sounds help healthcare providers identify issues like infections, asthma, or other lung conditions. They are an important part of a physical exam, providing clues about lung health without invasive procedures. Each sound pattern gives insight into what might be happening inside the respiratory system.
