Detailed explanation-1: -Adventitious sounds refer to sounds that are heard in addition to the expected breath sounds mentioned above. The most commonly heard adventitious sounds include crackles, rhonchi, and wheezes. Stridor and rubs will also be discussed here.

Detailed explanation-2: -Normal lung sounds are generated by the air flow in the respiratory tract and are characterized by broad-spectrum noise. Adventitious lung sounds are additional sounds superimposed on normal lung sounds, which can be continuous with a musical character (ie, wheezes), or discontinuous and explosive (ie, crackles).

Detailed explanation-3: -The presence of equal bilateral breath sounds indicates that both lungs are inflating equally with a given breath, which means the airways leading from the mouth to alveoli are likely to be intact and the chest cavity is free from air/blood that would prevent lung expansion.

Detailed explanation-4: -Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales). Rhonchi. Sounds that resemble snoring. Stridor. Wheeze-like sound heard when a person breathes. Wheezing. High-pitched sounds produced by narrowed airways.
