158 Annals of Thoracic Medicine - Vol 10, Issue 3, July-September 2015 Auscultation of the respiratory system Malay Sarkar, Irappa Madabhavi 1 , Narasimhalu Niranjan, Megha Dogra 2 Abstract: Auscultation of the lung is an important part of the respiratory examination and is helpful in diagnosing various respiratory disorders. Auscultation assesses airflow through the trachea-bronchial tree. It is important to distinguish normal respiratory sounds from abnormal ones for example crackles, wheezes, and pleural rub in order to make correct diagnosis. It is necessary to understand the underlying pathophysiology of various lung sounds generation for better understanding of disease processes. Bedside teaching should be strengthened in order to avoid erosion in this age old procedure in the era of technological explosion. Key words: Breath sound, bronchial breathing, crackles, rubs, wheeze T he auscultation of the respiratory system is an inexpensive, noninvasive, safe, easy- to-perform, and one of the oldest diagnostic techniques used by the physicians to diagnose various pulmonary diseases. History taking and a detailed physical examination, including the time-honored sequence of inspection, palpation, percussion, and auscultation should be considered an essential part of clinical examination, even in 21 st century with explosive advancement in technology related to health sciences. Technologic advancement has led to erosion in the bedside teaching due to overreliance on laboratory testing; therefore, the clinical relevance of auscultation has receded significantly in recent years. It was Hippocrates who began the concept of auscultation by applying ear to the patient’s chest to hear transmitted breath sounds and called this procedure as “immediate auscultation”. He described this as a method of direct auscultation. However, with the invention of stethoscope by Rene Theophile Hyac in the Laënnec in 1816; the art of auscultation not only became popular worldwide, but also comfortable for patients and physicians. Laënnec published his seminal work in 1819 in his masterpiece, “A Treatise on the Diseases of the Chest” .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
