What condition results in congested airways producing musical-like sounds during breathing?

The condition characterized by congested airways that produce musical-like sounds during breathing is known as "ronchi." This term describes low-pitched, rattling sounds caused by the obstruction of air flow in large airways, often due to mucus or other secretions. These sounds can be likened to a snoring or gurgling noise that can be heard either through the stethoscope or unaided, making them particularly recognizable.

While stridor is a high-pitched sound usually involving upper airway obstruction, crackles are sudden lung sounds typically associated with fluid in the alveoli, like in pneumonia or heart failure. Eupnea refers to normal, unlabored breathing and does not pertain to any abnormal sounds during respiration. Understanding these distinctions reinforces why "ronchi" is the appropriate choice for describing the presence of congested airways that create musical-like noises.
