4 both sides anterior 4 both sides posterior
how many places do you ausculate on posterior chest?
5 (both sides)
if the e sound is very nasal/changes to an "a", blank is present

intermediate
crackles in the dependent (lowest) portions of the lungs may be heard after prolonged?
recumbency
if bronchovesicular or bronchial sounds are head in areas outside of normal, suspect?
replacement of air filled lungs by fluid or tissue consolidation
where can you hear bronchovesicular sounds? (3)
1st interspace 2nd interspace between scapula (posterior)
one special technique is the 6 minute blank test which can used to assess COPD, can predict clinical outcomes
6 minute walk test (need 100 foot hallways)
if patients 60 or older have a forced expiratory time of 9 seconds or more are 4x more likely to have?
COPD
3 tests for transmitted voice sounds
Egophony ("ee" sound) Bronchophony ("ninety-nine") whispered pectoriloquy {whispered "ninety-nine")
fine, late, inspiratory crackles that persist from breath to breath suggest?
abnormal lung tissue
in severe asthma, wheezes and breath sounds may be absent due to blank. Is this serious?
absent due to low respiratory airflow, the "silent chest" this is a medical emergency
what are adventitious sounds?
added (abnormal) sounds not part of normal breathing
crackles (aka rales) wheezing rhonci are types of blank sounds
adventitious (added) abnormal breath sounds
the intensity of breath sounds indicates?
air flow rate (decreased sound indicates decreased flow like in COPD, or when transmission of vibrations is compromised)
how many places do you auscultate on anterior chest? lateral?
anterior - 3 (on both sides of sternum) lateral - 2
in some normal people, crackles may be heard in the blank lung bases after maximum expiration
anterior lung bases
blank is the most important examination technique for assessing air flow through the tracheobronchial tree
auscultation
a silent gap between inspiration and expiration suggests blank breath sounds
bronchial breath sounds
loud, harsh, higher pitched normal breath sound with a short silence between inspiration/expiration. Expiration lasts longer than inspiration
bronchial sound, a normal breath sound
which sound has longer expiration than inspiration?
bronchial sounds (loud intensity/high pitch)
if you can hear "ninety-nine" clearly, the paitent has a transmitted voice sound called?
bronchophony (loud voice sound)
what type of sounds is inspiration and expiration almost equal?
bronchovesicular
a normal breath sound that is equal in length in inspiration and expiration, at times separated by a silent interval/gap.
bronchovesicular, a normal breath sound
what do you check if there is abnormal sounds during auscultation?
check for transmitted voice sounds
loud, lower pitched crackle -350 Hz/15-30 miliseconds
coarse crackles
discontinuous adventitious sound that is intermittent, nonmusical, and brief
crackles (rales)
these sounds arise from abnormalities of the lung parenchyma (functional tissue) and can be caused by pneumonia, interstitial lung disease, pulmonary fibrosis or abnormalities of the airways
crackles/rales
what part of your stethoscope is used to listen to breath sounds?
diaphragm (best for high pitched sounds), used directly on skin
when the patient whispers "ninety-nine" the voice should be blank and blank, if at all
faint and indistinct, if it can be heard clearly, the patient has whispered pectoriloquy
special test to assess expiratory phase of breathing, patient takes a deep breath and then breathes out as completely and quickly as possible
forced expiratory time
placing one hand on the sternum and the other on the thoracic spine and then squeezing is a special test for?
fractured rib - if this test is positive the localized pain will increase (distant from the areas your hands are squeezing on)
if crackles, wheezing, or rhonchi clear after coughing/postion change, this suggests?
inspissated secretions (thickened secretions due to dehydration) associated with bronchitis/atelectasis (collapse of lung)
when percussing the anterior chest, check for blank dullness and blank tympany, which may be displaced by hyperinflated lung due to COPD
liver dullness stomach tympany
during egophony, the patient says "ee" and you will hear?
long E sound (bleating)
breath sounds are usually louder in the lower blank lung fields
louder in the lower posterior lung fields
where do you look for retraction during the posterior exam? (1)
lower intercostal muscles during inspiration
where do you look for retraction during the anterior exam? (2)
lower intercostal muscles during inspiration supraclavicular region
before auscultation, ask patient to cough to clear?
mild atelectasis (deflated air sacs) or airway mucus (these can produce unimportant extra sounds)
the patient should be instructed to breath through their?
mouth (larger airway, can move more air, obstructed nasal passages can affect sound)
during bronchophony, the paitent says "ninety-nine". The sounds should be blank?
muffled and indistinct
in cold/tense patients, you may hear?
muscle contraction sounds, muffled/low pitched rumbling/roaring
where can you hear vesicular sounds?
over most of the lungs
where can you hear bronchial sounds?
over the manubrium (larger proximal airways)
stridor/laryngeal sounds are loudest over the blank, while wheezes/rhonchi are faint or absent in this area
over the neck
coarse, grating sounds heard primarily during expiration
pleural rubs
pleural rubs may be heard in? (3)
pleurisy pneumonia pulmonary embolism
localized bronchophony and egophony are seen in lobar consolidation caused by blank
pneumonia
the crackles of heart failure are best heard in the posterior blank lung fields
posterior inferior lung fields
patients with COPD tend to prefer to sit blankly, with lips pursed during exhalation and arms supported by knees/table
prefer to sit leaning forward
clothes, gowns, and hair can cause crackling sounds. How do you manage the chest hair?
press harder
patient is supine for anterior chest examination. How can you make a patient with difficulty breathing more comfortable for this?
raising the head of the bed
relatively low pitched (150-200 Hz) with snoring quality last over 80 miliseconds
rhonchi
a low pitched wheeze that is unrelated to airway secretions
rhonchi (some suggest not using this term)
stridor is a blank sound
tracheal sound
loud, harsh sounds heard over the trachea
tracheal sound, a normal breath sound
if you hear abnormally located bronchovesicular/bronchial breath sounds, assess blank
transmitted voice sounds (may signal pneumonia or pleural effusion, which block airways with inflammation or secretions)
fever cough bronchial breath sounds egophony blanks the likelihood of pnuemonia
triples
inspiratory sound lasts longer than expiration in blank sounds (type of normal sound)
vesicular (fade out after 1/3 of expiration)
4 normal breath sounds?
vesicular (soft/low pitch) Bronchovesicular (equal length I/E, may be gap) Bronchial (loud/harsh/high pitch/gap/long E) Tracheal (loud/harsh/over the trachea)
a soft/low pitched normal breath sound that is heard throughout inspiration, continue without pause through expiration and then fade away 1/3 of the way through expiration
vesicular breath sound (normal/soft/low pitch)
high pitched (over/= 400Hz) with hissing or shrill quality last over 80 miliseconds
wheezes
these sounds arise from narrowed airways due to asthma, COPD, or bronchitis
wheezes
continous abnormal breath sounds that are sinusoidal (fluctuate in a repetitive pattern), musical, and prolonged
wheezes/rhonchi
can chest expansion/lung excursion be done anteriorly?
yes
is tactile fremitus assessed anteriorly?
yes
