Compare One Side To The Other Looking For

Compare one side to the other looking for asymmetry. Note the location and quality of the sounds you hear. Thorax auscultation More often doctors use a stethoscope with two To expansions on the end. One has races - with a diaphragm and it Expansion (strengthens sounds) listen to weak sounds the chest is more often Cages - for example, breath sounds. Pay attention to place and quality of sounds which are listened. Interpretation Breath sounds are produced by turbulent air flow. They are categorised by the size of the airways that transmit them to the chest wall (and your stethoscope). The general rule is, the larger the airway, the louder and higher pitched the sound. Vesicular breath sounds are low pitched and normally heard over most lung fields. Tracheal breath sounds are heard over the trachea. Bronchovesicular and bronchial sounds are heard in between. Inspiration is normally longer than expiration (I> E). [2] Breath sounds are decreased when normal lung is displaced by air (emphysema or pneumothorax) or fluid (pleural effusion).
