d. Auscultate normal breath sounds. Auscultate (examine by listening) normal
breath sounds in accordance with table in 2-2.
Table 2-2. Auscultated normal breath sounds.
e. Auscultate vesicular breath sounds (figure 2-12). These sounds are normally
heard over the entire lung surface, except beneath the manubrium sterni and in the
interscapular region. The sounds are long when the patient inhales and short when the
patient exhales.
Figure 2-12. Auscultation over lung surfaces.
f. Auscultate bronchial (tubular) breath sounds (figure 2-13) . These sounds
result from consolidation or compression of the pulmonary tissue that assists in the
transmission of sound from the bronchial tree. Bronchial breath sounds do not occur in
the normal lung except directly over the trachea. These sounds are short when the
person breathes in and long when the person breathes out. The sounds are usually
louder than vesicular breath sounds. .
