Bronchial Sounds
Breath sounds are similar to tracheal sounds in that
the expiratory phase is louder and lasts longer than the
inspiratory phase. The major distinguishing characteristic is
the high pitched, harsh quality of the expiratory phase.
Posterior
(Four Sites)
Wheezing Sounds
These musical wheezing sounds are often heard in asthma
patients. During inspiration, the wheeze is slightly higher in
pitch than during expiration. Wheezing in asthmatics is often
present in either one or both phases of respiration.
Pleural Friction
This sound originates from the friction of inlamed pleural
surfaces moving against one another. The sound is repetitive
as long as the breathing pattern and position remain
constant. Similar to but lower in pitch than crackles.

Medium-Fine
Crackles
These noises begin about mid-inspiration and progressively
increase in intensity up to the end of expiration. Coarse
crackles are also audible in the early expiratory phase of
some of the breaths.
Ronchi, Crackles
Coarse crackles are present during both inspiration and
expiration. There are also some very low pitched repetitive
sounds that are ronchi. High pitched squeaks are also audible
against a background of bronchial breath sounds.
Coarse Crackles
Coarse crackles begin at the onset of inspiration and diminish
in intensity and prevalence toward the end of inspiration.
Expiration is not audible.
Pulmonary Edema
Coarse and medium crackles appear toward the end of
inspiration and continue into expiration. The respiratory rate is
rapid and expiratory phase is “bronchial” in character. These
features exist during respiratory distress and congestion.
