Which type of lung sounds are associated with congestive heart failure?

In the context of congestive heart failure (CHF), rhonchi and crackles are the lung sounds commonly associated with this condition. Congestive heart failure often leads to pulmonary edema, where fluid accumulates in the lungs. This fluid interferes with normal air movement and creates abnormal sounds.

Crackles, also referred to as rales, are short, explosive sounds resembling popping and often indicate the presence of fluid in the alveoli. This is particularly evident during inspiration. Rhonchi, on the other hand, are low-pitched, continuous sounds that may occur when air passes through larger airways obstructed by mucus or other abnormalities, often indicative of fluid or secretions.

The combination of rhonchi and crackles signifies the impaired respiratory function due to excess fluid, a hallmark of congestive heart failure. This auditory feedback can help EMTs and healthcare providers assess the severity of the patient's condition and make informed decisions about treatment.
