![]() Normal breathing sounds clear and smooth. They detect specific sounds that help them understand lung health. When doctors listen to lungs, they hear more than breaths. Understanding Lung Sounds and Abnormal Breath Types The identification of these lung sounds plays a crucial role in the assessment of respiratory health and the determination of underlying conditions. Rhonchi suggest blockages in larger airway passages due to secretions or swelling.Rales are associated with fluid accumulation at a smaller scale within the alveoli.Rhonchi: Low-pitched possible during both inhalation and exhalation.įurther differentiation is found in their indicative conditions:.Rales: High-pitched predominantly during inhalation.Conditions that can lead to rhonchi include chronic bronchitis and COPD (Chronic Obstructive Pulmonary Disease). These sounds occur when there is an obstruction in the larger airways of the lungs, often due to mucus buildup or inflammation narrowing the air passages. Rhonchi, on the other hand, are low-pitched noises that may mimic the sound of snoring or moaning. These sounds suggest the presence of fluid in the small airways or alveoli of the lungs, commonly associated with conditions such as pneumonia, heart failure, or pulmonary fibrosis. They resemble the sound of opening a Velcro strip or rubbing hair between fingers close to the ear. ![]() Rales are fine, short, crackling sounds heard in the lungs with a stethoscope during inhalation. Each sound indicates different underlying conditions and helps in diagnosing specific lung problems. Rales and rhonchi are two types of lung sounds that medical professionals listen for to assess a patient's respiratory health.
