![]() ![]() In the fall of 1816 (a year after the battle of Waterloo), he was summoned to the bedside of a young woman with a chest illness. The hero of this rediscovery was an introverted, diminutive, very asthmatic, very prudish, and very tuberculotic Breton physician, named René Théophile Hyacinthe Laënnec. It took a lot of serendipity (and plenty of shyness) to rekindle it as indirect auscultation, that is, one “mediated” by a newly invented cylindrical instrument, the stethoscope. by the sound they make.” Yet, during the 18th and early 19th centuries, direct auscultation fell rapidly out of favor, being replaced by a newer diagnostic modality: chest percussion. He wrote, “Who knows? It may be possible to discover the motions of internal parts. The hypochondriacal Robert Hooke, an assistant to Robert Boyle and one of the first scientists to use the word cell (1664), even had a good insight in describing heart sounds. Since then, chest auscultation was mentioned by Caelius Aeralianus, Leonardo Da Vinci, Ambroise Paré, William Harvey, Giovanni Battista Morgagni, Gerhard Van Swieten, William Hunter, and many others. In fact, Hippocrates himself taught and practiced auscultation, advising physicians to apply their ears to the patient’s thorax in order to detect various diagnostic sounds. 1400–1200 BC), and the Hippocratic writings (4th century BC). References to breath sounds first appeared in the Ebers papyrus (c. Philadelphia: Lippincott Williams & Wilkins.Auscultation of the direct or immediate variety (that is, without the use of the stethoscope) has actually been around for a long time. Brunner & Suddarth's Textbook of Medical-Surgical Nursing. Do you have an easy acronym or pearl for remembering breath sounds, or some test-taking strategies to share?īreath Sounds Reference Hinkle, J. Reviewing what you know and thinking about each response choice can help you focus in on the correct answer. During lung auscultation, crackles are heard in pulmonary fibrosis, which is choice B. There would be loss of breath sounds over the area of a pneumothorax as there is no air movement in the area of auscultation. In general, there are not specific adventitious breath sounds associated with neuromuscular disorders.Ī pneumothorax is a collapsed lung. ![]() Diaphragmatic weakness can lead to hypoventilation chest wall muscle weakness can lead to ineffective cough and upper airway muscle weakness can lead to difficult swallowing and ineffective clearing of upper airway secretions. Neuromuscular disorders can cause respiratory problems through several pathways as the muscles responsible for breathing are affected. The crackles are the result of the snapping open of collapsed, stiff alveoli. This may be hard to distinguish from congestive heart failure. The most common adventitious breath sound associated with pulmonary fibrosis is fine bibasilar crackles. This scarring leads to thickness and stiffness in the lungs. Pulmonary fibrosis is a form of interstitial lung disease in which scarring (or fibrosis) is the hallmark clinical feature. For testing purposes, however, expiratory wheezes are associated with asthma. Initially the wheezes are expiratory but depending on confounding factors or worsening clinical symptoms, there may be inspiratory wheezes, rhonchi or crackles. As air moves through these narrowed airways, the primary lung sound is high-pitched wheeze. This response is triggered by an irritant, allergen, or infection. The resulting physiologic response in the airways is bronchoconstriction and airway edema. AsthmaĪsthma is a condition mediated by inflammation. In this instance, it would be helpful to go through each clinical condition separately and predict what you may hear on auscultation. Now, let’s think about test-taking strategies.
