What are Rales?
The Rales are abnormal lung sounds characterized by discrete non-musical crackling or popping noises. These sounds are typically heard during inspiration but may also be present during the expiration. Rales can be further classified into two subtypes: fine and coarse. Fine rales are high-pitched and soft resembling the sound of hair being rubbed between the fingers. Fine rales typically suggest conditions like pulmonary fibrosis or early congestive heart failure while coarse rales can be indicative of conditions like bronchitis or pneumonia. They are often indicative of an underlying respiratory or pulmonary condition. Rales are typically heard with the stethoscope placed on the chest while the individual breathes in and out. These sounds can provide important diagnostic information to healthcare professionals.
