Definition: Pneumography, also known as lung auscultation or breath sound examination, involves the systematic evaluation of the chest by a trained professional, such as an audiologist or pulmonologist, using a stethoscope and other instruments to listen for abnormal sounds that may indicate conditions like pneumonia. The primary goal is to detect any signs of disease in the lungs, including inflammation, obstruction, or foreign bodies, which can be life-threatening if left untreated.
