Final answer:
Adventitious breath sounds are classified into continuous (wheezes) and discontinuous (crackles). Continuous sounds are long musical sounds, while discontinuous sounds are brief popping noises, each indicating different respiratory conditions.
Step-by-step explanation:
The two classifications of adventitious breath sounds are continuous and discontinuous.
Continuous adventitious sounds, also known as wheezes, are musical, prolonged, and typically heard during expiration. They are indicative of airway narrowing or obstruction. Examples include asthma, emphysema, or chronic bronchitis. Discontinuous sounds, or crackles, are brief, intermittent, popping sounds. These sounds are associated with conditions such as pneumonia, heart failure, or interstitial lung disease. Identifying these breath sounds is crucial for health professionals to assess respiratory status and diagnose underlying conditions.
