What are the main rules of lung auscultation?
Auscultation of the lungs should be systematic, including all lobes of the anterior, lateral and posterior chest. The examiner should begin at the top, compare side with side and work towards the lung bases. The examiner should listen to at least one ventilatory cycle at each position of the chest wall.
In what order do you Auscultate heart sounds?
There are two normal heart sounds that should be elicited in auscultation: S1 (lub) and S2 (dub). The practitioner should listen over each of the four main heart valve areas: the aortic, pulmonary, tricuspid and mitral valve areas. They should also listen for any additional sounds such as clicks, and heart murmurs.
