Rails, also known as crackles or rales, are abnormal lung sounds heard during auscultation with a stethoscope. They are characterized by a series of short, popping sounds and typically indicate the presence of fluid in the airways or alveoli, often associated with conditions like pneumonia, heart failure, or pulmonary fibrosis. Rails can be categorized as fine or coarse, depending on their sound characteristics and the underlying cause of the lung pathology. These sounds are important clinical signs that help healthcare providers assess respiratory conditions.
