1. Identification
2. History taking
a. CHIEF COMPLAINTS
o Chest pain
o Cough â sputum and blood
o Breathlessness (dyspnea)
o Cyanosis
o Wheezing
o Sore throat that associated with cough
Chest pain
īˇ SIQORAAAī Site, intensity, quality, onset, radiation, etc
īˇ Causes
o CVS
o GIT
o Respiratory
o Miscellaneous problem
īˇ CVS Causes
o MI â death to heart muscle due to lack of oxygen
o Angina pectoris â pain caused by lack of oxygen (no necrosis) (stable, unstable,
prinztemal)
o Percarditis â infection of the pericardium and inflammation of the pericardium
o Thromboembolism (PT)
o Dissecting aortic aneurysm
ī§ Aneurysm is an abnormal, permanent dilatation of a blood vessel
ī§ Most common aortic aneurysm is the descending aorta
ī§ Also the aneurysm is commonly found in the arch of the aorta
ī§ Tearing type of chest pain that radiates to the back
īˇ GIT Causes
o Esophagus problem
ī§ Inflammation â esophagitis
ī§ Spasm of esophagus
ī§ GERD â reflux disease
īˇ Gastric contents from stomach refluxing to esophagus
ī§ Esophagus carcinoma
ī§ Peptic ulcer
2. 2
o Stomach
ī§ Gastritis of the upper part of the stomach
ī§ Peptic ulcers
īˇ Respiratory Causes
o Lung parenchyma do not have nerve ending, therefore you canât feel pain
o Any involvement pathology of pleural would lead to chest pain
o Upper Respiratory Tract
ī§ Mostly talking about the trachea
ī§ Inflammation of the trachea â trachitis but bronchioles usually involved ī
upper bronchie, tracheabronchitis
ī§ Site of pain ī upper sternum or parasternum
ī§ Intensity ī moderate to severe
ī§ Qualityī
ī§ Character ī sharp pain, can be burning
ī§ Onset ī acute
ī§ Radiation ī no radiation
ī§ Aggravating factorī coughing (not as much) will cause more pain and
cause breathlessness, smoking
ī§ Alleviating factor ī coughing more alleviating factor
ī§ Associated factorī breathlessness, fever, malaise, cough
o Lower Respiratory Tract
ī§ Conditions that lead to chest pain would have pleura involvement
ī§ Causes: every pathology of the lung can lead to pain cause every
pathology involved the pleura
īˇ Pleuritis
īˇ Pleural effusion ī accumulation of exudates fluids
īˇ Pneumothorax, hydrothorax
īˇ Empyema
īˇ Hemothorax
īˇ pneumonia
ī§ The lower respiratory does not have any nerve endings, only the pleura
has nerve endings
ī§ Site depends on pathololgy and intensity same depends on pathology
ī§ Pluera are the coverings of the lungs ī visceral pleura and parietal pleura
ī§ Quality/Characterī sharp knife like pain
ī§ Aggravating factor ī pain increased during inspiration is an
important signed of pleuritis, take deep breath and if pain is
aggravating pleaura is involved

īˇ CVS cause
o Basically, only left sided of the heart is involved
o Left heart failure ī failure of the heart to properly function; failure of the heart to
have normal cardiac outputī failure of heart to pump the blood and backs up into
the lungs
o Obstruction of the mitral valve is the most important causes
ī§ Mitral stenosis ī lumen decreases, narrowing of the lumen
o Mitral regurgitationī two leaflets(unidirectional), pathology of leaflets, defect in
the mitral valve, some blood goes back (regurgitates)

pleuritis chest pain ī more air comes in pleural cavity
īˇ Male, young, Tall and thin people have more chance of getting
spontaneous pneumothorax because of narrow chest, so less
expansion of chest wall,

Monday 9-17-12
EXAMINATION OF POSTERIOR CHEST WALL
īˇ Best position is the sitting position with his hands in front of his chest and hands over his
opposite shoulder (crossed arms over chest on opposite shoulders) â scapula depressed
laterally, more surface area, increase the lung field
īˇ Tell patient to take in a breath
Inspection
17. 17
1. Shape of chest wall
īˇ Use your eyes to look for the shape of the chest. Normal shape of the chest is
elliptical. Itâs have two diameter
o Transverse diameter â if transverse is more than anterior posterior diameter =
normal chest wall (one lateral side to the other lateral side)
o Anterior posterior diameter (from anterior to posterior)
īˇ Abnormality of the chest wall
o Barrel chest wall
ī§ Anterior posterior and transverse diameter is approximately the same.
Increase anterior posterior because of increase in compliance
ī§ Causes (COPD) (expiration problem air (pockets) stays in chest wall),
increase in lung compliance (volume/pressure)
īˇ Chronic bronchial asthma
īˇ Chronic emphysema
īˇ Bronchiolestasis âirreversible dilation of bronchial tree
īˇ Chronic bronchitis
o Pigeon chest = pectus carinatum
ī§ Chest with shape of a pigeon = sternum is protruding. Abnormal
protruding of the cartilage sternum
ī§ Abnormal increase in anterior posterior diameter so therefore anterior
posterior and transverse diameter are approximately the same
ī§ Causes
īˇ COPD
īˇ Usually in pre pubertal boy (10-14 yrs)
īˇ Post surgical after heart surgery
īˇ Children (normal 0-2.5yrs)
īˇ Bone congenital abnormalities
o Marfans Syndrome
o Trisomy 21 (Downs)
o Osterogenic imperfect (Type 1 collagen)-AD but
sporadic
ī§ Can be associated with trisonomy-18 (Edwards) and tri-21,
osteomalacia
ī§ More chance of mitral valve prolapsed
o Funnel Chest = pectus excavatum
ī§ Posterior displaced lower part of the sternum
ī§ Broad upper chest wall with a thin lower chest wall. Lower part of the
sternum is depressed. Once depression of lower part of sternum, the
rib cage get narrow
ī§ Causes
18. 18
īˇ Congenital problem (lower part of the sternum is displaced
posteriorly)
īˇ Ricketts
ī§ Can be associated with mitral valve prolapsed and Turnerâs syndrome
o Flail Chest
ī§ Seen in severe trauma to chest wall (ex. Multiple Fractured rib)
ī§ Deflation during inspiration
ī§ Inflation during expiration
ī§ These are known as paradoxical movements = due to change in
internal pressure.
ī§ Complication of flail chest = pneumothorax
īˇ 2. Look for deformities in the chest wall that leads to assymetry
Swelling # of breast, # of nipples lesions of chest wall, spine
Abnormal spine---rib pump-scoliosis
Ant post curvatture-thyphosis
largosis-lumbar motor
Sinus crack-bathing from interior to exterior-causes include severe Bacteria infection
viral infection eg TB-Actinomycetes (bact)
o Kyphosis â anterior displacement of the spine
o Scoliosis â lateral displacement of the spine
o Swelling or outgrowth on one side of the chest wall
o Lordosis-inward curvature of vertebral column
īˇ 3. Look for abnormal retraction of interscapular muscles = sign of respiratory
distress (pt is probably using accessory muscles if contracting, ex. using
sternocleidomastoid)
o If someone have respiratory distress they would use the interscapular muscles
a lot. Therefore look for abnormal retraction of interscapular muscle
īˇ 4. Look for chest expansion
o Bilateral respiratory movements
o Compare chest expansion with right and left
o During inspiration = expansion of chest wall
o During expiration = deflation of chest wall
o See of the expansion of the chest is symmetrical with both sides
o Abnormality = asymmetrical (decrease expansion in one side)
ī§ Cause
īˇ Any pathology that would lead to decrease in lung capacity
(volume) = lung obstruction. Example, lung effusion
īˇ Pleura effusion
īˇ atelectasis = lung abscess
19. 19
īˇ exam â know which side is affected if there is right sided
decreased expansion, or left sided expansion.
īˇ right sided pleural effusion leads to left sided expansion
īˇ Asymmetrical chest expansion is abnormal. The abnormal side
expands less and lags behind the normal side. Any form of
unilateral lung or pleural disease can cause asymmetry of
chest expansion
īˇ Let us say that the patient has decreased chest expansion on
right side. Now that we know the abnormal side is right, with
the mediastinum shifted to left, then it would mean a pushing
lesion from right. The pushing lesions are pneumothorax,
pleural effusion and large mass. The next step will help us
narrow down those possibilities.
5. Look at position of trachea
Palpation
īˇ Aim of palpation is to confirmed inspection findings
īˇ Use your hands = palms, fingers
Abnormalities
īˇ 1st Shape of the chest: 2nd chest deformities
īˇ Swelling of chest wall (but can be used for any type of swelling, not only for chest wall)
o 2nd
Size of swelling, have an approximate idea of how big it is, ex 2 cm
o 1st
Location of swelling (use anatomical landmarks); be precise as possible
ī§ Ex. Right anterior chest â can be clavicle, sternum, ribs,
o 3rd
Shape of the swelling
ī§ Round
ī§ Square
ī§ Irregular
o 4th
Consistency of swelling
ī§ How does it feel when you feel the swelling
ī§ Ex. Soft = fat cells ī lipoma
ī§ Firm ī dermoid cyst
ī§ Hard ī Calcification and sclerosis
o 5th
Look for punctum = look like a mole (mole discoloration)
20. 20
ī§ Punctum on swelling = sebaceous cyst
o 7th
Inflammatory signs
ī§ Tenderness, pain, warmness, swelling,
o Does the swelling have any discharge
ī§ Purely = abscess
o 6th
Mobility of swelling
ī§ Use two fingers, thumb and index and try to move in all directions
ī§ If its benign = no fixation
ī§ if its fixed (attachment to underlying surface) = tumors/carcinoma
o 8th
Sinus tracts on chest wall
ī§ Opening from interior to the exterior
ī§ Two important causes relate to chest wall
īˇ Complication of tuberculosis (opening on chest wall)
īˇ Chlamydia infections (actinomycetes)
ī§ Look for any discharge coming out of it, if there is discharge, take a swab
and send it to laboratory
īˇ 3rd Tenderness on chest wall
o No pain and when one touches chest wall u get pain
=tendernessī inflammation
o If you palpate a rib and you get tenderness = fracture ribs
o Palpate and get pain and tenderness between ribs (intercostals space) = pleuritis
o Tietzeâs syndrome = costal condritis (close to sternum)
o Muscle spasm
o
īˇ 4th Chest expansion Respiratory movements or chest expansion
ī§ Always compare right and left â both should be expand symmetrically
ī§ If there is a decrease expansion in one side
īˇ Any respiratory pathology that reduce chest expansion on one side
(that side that is reduced has the problem) (ex. Pleural effusion,
lung abscess, hydrothorax)
ī§ Lung collapse
īˇ Absence of lung expansion of the side that is collapsed
īˇ Atelectasis â decreased or absent air in the entire or part of a lung.
o If atelectasis (lung collapse) you probably wonât feel
anything = absence of vibration/respiratory expansion
absence
5th Tactile or vocal fremitus
īˇ Make patient speak (say 99 or 123)
īˇ Your epiglottis works, vocal words
21. 21
īˇ Speech apparatus
īˇ Sound waves that start from larynx go to nasopharynx ī through
respiratory treeī trachea ī bronchioles ī chest wall
īˇ By telling the patient to say something, you can feel the vibration =
If there is no obstruction
o If obstruction there will be decreased vibration, ex
pneumonia, pleaural effusion (due to obstruction)
o If atelectasis (lung collapse) you probably wonât feel
anything = absence of vibration/respiratory expansion
absence
īˇ Compare the right and left using ulna surface of palm (pinky), tell
patient to say numbers and feel
â TUESDAY 9-18-12
Percussion-if ur percussion is solid liquid or gas
Use both middle fingers (interphalangeal joint), movement should be at the wrist
Two steps

iii. Hyperresonance â more than normal amount of air in the lungs; too much
gas
iv. Examples = Pneumothorax, emphysema
v. Tympani â when percussed on airway with a lot of pressure/volume
1. Example = Tuberculosis, some pneumothorax. Only seen in some
case of tuberculosis
2. Best place is abdomen in stomach, air bubble under extreme
pressure
3. Drumlike sound
b. Exam question
i. Upon palpation, you find an 8 cm mass what note is heard
1. Mass is too deep to hear the note
2. Dull
3. Resonance
22. 22
4. Tympany
5. hyperresonance
c. Each percussion notes have three characters
i. Duration
ii. Pitch-
iii. Intensity-
Intensity Pitch Duration
Dull MEDIUM MEDIUM MEDIUM
Resonance LOUD LOW HIGH-LONG
Hyperresonance LOUDER LOWER HIGH-LONGER
Typani HIGH (LOUD) HIGH DEPEND on the
tube(short
airway-short)
If intensity is lower on one side there is still pathology, even if there is resonance on both sides.
2. Second step in percussion = diaphragmatic excursion (diaghram goes down on
inspiration)
a. Tell patient to take a deep breath and then exhale and keep it in expiration mode
b. Start on the middle of the scapula and go down to the diaphragm â goes from
resonance to dull
c. Start from resonance and go till you get a dull notes = level of diaphragm during
expiration
d. Do the same for inspiration mode
e. Marked the distance = 2 cm is normal
f. Greater than 2 cm = diaphragm is not contracting fully or completely. The
pathology where the lung capacity is low
i. Example = pleural effusion, pneumonia
g. Compare the level of diaphragm on both sides. The level of diaphragm of both
side should be the same = pathology of higher diaphram
i. If the level of diaphragm is high on one side
1. Atelectasis, pleural effusion, something wrong with the
diaphragm., something taking up space in lung cavity
2. Intervation-phrenic nerve
3. Congenital diaghram
h. Dullness should be the same on the same (both) side
i. Low diaghram is normal
Organ and percussion surface should be less than 6cm
23. 23
Auscultation (breath sounds, adventitious, transmitted)
i. Breath sounds
ii. Vesicular breath sounds (low pitch)
1. Inspiration is longer than expiration (less pressure) without gap.
Heard all over the back and lung fields
2. If u hear bronchial breath sounds, some path that obstructs air way,
and narrows air way, pneumonia
iii. Bronchial (high pitch)
1. Heard where you have bronchi, over the upper sternum
2. Heard on the bronchi only (narrower)
3. Expiration is longer than inspiration and gap is present
iv. Bronchovesicular (intermediate) sternal angle
1. Inspiration and expiration is the same without a gap
2. Expiration may be longer but there shouldnât be a gap
3. Seen at the 1st and 2nd intercostal space and the anterior chest
v. Tracheal (high pitch)
1. Inspiration and expiration are equal but there should be a big gap
2. Place stethoscope on trachea
3. Inspiration could be longer
vi. Auscultate with diaphragm and compare one side with the opposite side
24. 24
vii. Look for the type of breath sound and the intesnsity of the breath sound
viii. If intensity is decreased on one side, there is a pathology on that side. Ex-
pleural effusion, lung abscess
ix. Adventious breath sounds
1. Crackles/Rales
a. Discontinuous breath sounds (heard without sounds)
b. Duration = 3-5milliseconds or 15-30 milliseconds
i. Bronchiectasis â postâĻ
ii. Deflated airways that tries to open
c. Pitch
d. Creaking cracking, popping quality
i. FINE (soft in nature) high pitch 5-10 milliseconds
1. Parenchyma of lungs, pulmonary fibrosis,
pneumonia
ii. Coarse (loud) low pitch 30-40 milliseconds
1. Bronchiectasis postâĻ
iii. Heard in inspiratory
1. Early inspiratory crackle
a. Bronchial asthma
b. Chronic bronchitis
2. Middle one third mid inspiratory crackle
3. Late inspiratory crackle (lower lobes)
a. Lung Fibrosis
b. Left heart failure
4. PAN inspiratory crackle-heard throughout
inspiratory
iv. Heard in expiratory (bronchiectasis)
1. Early expiratory crackle
2. Middle expiratory crackle
3. Late expiratory crackle
4. PAN expiratory
25. 25
2. Wheeze â high pitched! Continuous breath sound, character is
musical
a. Abnormal breath sound, heard during late inspiration or
early expiratory (sound during expiratory mostly)
i. Asthma
ii. Emphysema
iii. Bronchciestatisis
iv. all 4 COPDâs â chronic bronchitis, youâll hear more
crackles than wheeze
v. Left heart failureī cardiac asthma
3. Rhonchi â low pitched! Continuous but low pitch. where there are
large airway secretions. Characterī snoring quality.
4. Stridor, heard during inspirations, where there are obstruction of
upper air ways.
a. Pharyngitis
b. Anaphylaxis-edema in larynx
c. Croupī larynx tracheobronchitis
d. Laryngitis
5. Pleural rub = friction rub, sound heard on surface rub
a. Parietal and visceral pleura rub togetherī friction
b. Pleural effusion
c. Something between the pleura or fluid accumulation
i. Pleuritis best example
Transmitted-
īˇ Make patient speak and listen to sound transmission of sound waves from
respiratory system to surface area.
īˇ Normal lung tissue filters high pitch sounds
o Only low pitch sounds come to surface
1. Bronchophony- (+) get loud and clear 99
a. Ask pt to say 99 or 123 and listen to sounds
26. 26
b. Should only hear low pitch sounds, (muffled 99) is normal
c. If abnormal, you get high pitch clear 99
d. Consolidation phase in Lobar pneumonia, bronchial pneumonia
2. Egophony-
a. Ask patient to say eeeeeeeeee
b. If normal muffled eeeeeeeee
c. Pathology is involved eeee becomes loud aaayy
d. Consolidation phase in Lobar pneumonia
3. Whispering pectoriloquoy
a. Tell pt to whisper 123 or 99
b.
c. Normal u donât hear nothing
d. If whispers 99 u can hear 99 thatâs abnormal
e. Consolidation phase in Lobar pneumonia
4. Anterior chest
a. From above the 2nd intercostal space and below 5th intercostals can hear the same on
both sides
b. You can chest both sides
c. Anterior chest
i. During inspection, when pt. inspires, add the position of the trachea
ii. Trachea should be at the midline
iii. Confirm during palpation. = traits method. = use three fingers. 2 on
sternoclaviculare, feel tracheal rings. Anterior most part are most prominent.
Come down feeling the rings. Check the two distances from the midpoint
iv. Tracheal deviation = mediastinal shift.
v. Trachea towards the rights = pathology of right or left lung. Right lung =
atelectasis= deviation of trachea of the same sided lesion, everything else is
towards the opposite side
vi. Trailes procedure
27. 27
1. Use middle three fingers, sit up straight, place two out of three on
sternoclavicule prominence and then make sure the there is same
amount of space between the two fingers
-site of more negative pressure trachea deviates towards that side
-pleural effusion on right side, which side will trachea deviate
towards the left, increase pressure on the right side and lower on the
left side
Pleuaral effusion, hydrothorax, if increase pressure on one side
trachea deviates toward the other
Atelectacisī same side
