These sounds are audible when auscultation is performed using a stethoscope. Vesicular breath sounds occur when the vocal cords vibrate during inspiration and expiration, when the vibrations are transmitted to the trachea and bronchi. Cedar (2018) provides further information on the physiology of breathing. Fig 1 illustrates the anatomy of the lungs and Fig 2 highlights the location of the lung lobes from an anterior chest perspective. To undertake a thorough assessment of the chest, including auscultation, it is essential to understand the anatomy and physiology of the respiratory system. The Nursing and Midwifery Council (2018) has included chest auscultation and interpretation of findings in the Standards of Proficiency for Registered Nurses, and student nurses now learn this skill as undergraduates. This is an example of a systemic assessment tool but other tools are available (Simpson, 2015)
