LOCAL EXAMINATION OF THE CHEST

It is necessary for the patient to be stripped to the waist. Usually, the patient

lies in a recumbent or semi-recumbent position with arms abducted, when the

anterior and lateral aspects of the chest are being examined, and sit upright with

arms folded across the chest, when the posterior aspect of the chest is being

examined. When the patient cannot sit, the posterior chest may be examined by

turning the patient on his lateral sides. Always compare between identical points

or areas on both sides of the chest.

The right lung is composed of three lobes (the upper, middle and lower

lobes) separated from each other by the minor and major interlobar fissures,

while the left lung is composed of two lobes only (the upper and lower lobes)

separated by the major interlobar fissure only. The right lung is composed of 10

bronchopulmonary segments: the upper lobe has three segments (anterior, apical

and posterior), the middle lobe has two segments (medial and lateral) and the

lower lobe has five segments (apical, anterior, posterior, medial and lateral),

while the left lung is composed of 8 bronchopulmonary segments only: the

upper lobe has two segments (anterior and apicoposterior), the lingula has two

segments (superior and inferior) and the lower lobe has four segments (apical,

anterior, posterior, and lateral).

Surface anatomy of various organs :

1- Lungs : The apices of the lungs rise 2-3 cm above the medial thirds of the

clavicles. From this point the inner margins of the lungs and their covering

pleurae slant towards the sternum, meeting each other in midline at the

sternal angle, then on the right side: The lung margin continues down as far

as the 6th costal cartilage, where it turns laterally to meet the midclavicular

line at the 6th rib, the midaxillary line at the 8th rib and the scapular line at 10th

thoracic vertebra and then a line ascends along the paravertebral line to join

the apex. On the left side: The landmarks are the same with the exception

that the lung border turns away from sternum at 4th till the 6th costal cartilage

Page 2: pemeriksaan fisik paru

(to the parasternal line) where it turns laterally, due to the heart, which lies in

contact with chest wall in this area.

2- Pleurae : The pleura lies so close to the lungs at the apices and along the

inner margins, so following the same surface markings, but the at the lower

borders of the lungs the pleura extends farther (reaching the level of 8th rib in

the midclavicular line, level of the 10th rib in the midaxillary line and level of

12th thoracic vertebra in paravertebral line).

3- Kronig’s isthmus : a- Anterior: Medial 2/3 of the clavicle.

b- Posterior: Medial 1/3 of spine of scapula.

c- Medial: A line joining sternoclavicular joint with the 7th cervical spine

posteriorly.

d- Lateral: A line joining point A (junction of medial 2/3 of clavicle with

outer 1/3) and point B (junction of medial 1/3 of spine of scapula with

lateral 2/3).

4- Lung fissures: a- The oblique fissure (both lungs) : a line drawn from the 3rd thoracic spine

posteriorly slanting downwards and laterally to cut the 5th rib in the

midaxillary line and ends at the 6th costal cartilage anteriorly 3 inches

from middle line. It also divides the axilla into upper and lower axillary

areas.

b- The transverse fissure (right lung only): a line drawn laterally from the

costal cartilage of the 4th rib to meet the oblique fissure at the 5th rib in

midaxillary line.

6- Bare area of Heart: An area over the anterior chest wall extending from

the 4th to the 6th costal cartilages and from the left sternal border to the left

parasternal line.

7- Heart:a- Left 5th intercostal space, 3.5 inches from median plane.

b- Left 2nd costal cartilage, 1.5 inches from median plane.

c- Right 3rd costal cartilage, 1.0 inches from median plane.

d- Right 6th costal cartilage, 0.5 inches from median plane.

INSPECTION Chest is inspected from the head or from the foot. If the patient is too ill to sit

up, the back is examined by rolling the patient on each side in turn.

1- Shape of the chest: The healthy chest is an ellipse in cross section (the anteroposterior to

transverse diameters in the ratio of 5:7), bilaterally symmetrical with smooth

contours, the ribs are oblique and the subcostal angle is about 70-110o. Chest

diameters are measured by the pelvimeter. Abnormal shapes of chest that

may be present are:

a- Barrel chest : The anteroposterior diameter is increased, ribs are

horizontally placed with wide intercostals spaces, spine becomes concave

forwards, sternum is much more arched and the subcostal angle is obtuse.

This deformity is present in emphysema.

b- Funnel chest : An exaggeration of normal depression seen at end of the

sternum, often congenital but may be acquired in shoemakers (pectus

excavatum). It is due to fibrous replacement of the anterior portion of the

diaphragm. It is usually asymptomatic, but when there is marked degree

of depression of the sternum, the heart may be compressed and apex

shifted to left with reduction in the lungs ventilatory capacity.

c- Rachitic chest : A groove in the region of costochondral junctions during

inspiration (Harrison’s sulcus) with swellings of costochondral junctions

(Rachitic rosary).

d- Pigeon’s chest : The sternum becomes prominent and the chest acquires a

triangular form (pectus carinatum). The congenital form is due to

5

Page 6: pemeriksaan fisik paru

malinsertion of anterior portion of the diaphragm, being inserted in

posterior rectus sheath rather than the sternum while the acquired form

occurs in rickets.

e- Spinal deformities: kyphoscoliosis and lateral scoliosis.

f- Unilateral enlargement: pleural effusion, pneumothorax, lung or chest

wall tumors, compensatory emphysema and precordial prominence

secondary to pericardial effusion or valvular heart disease.

g- Unilateral retraction: fibrothorax and lung collapse.

2- Movement of the chest:a- Inspection is the best way of assessing any limitations of movements of

the chest.

b- The degree of chest expansion is measured by placing a tape measure

below the nipples and instructs the patient to breathe deeply in and out.

Normal chest expansion is about 4-6 cm. Generalized decrease of

movement means expansion less than 2cm.

c- Compare movement of the two sides while the patient is breathing

quietly. A delay in movement on one area means that there is an element

of bronchial obstruction in the corresponding bronchus e.g. adenoma or

early bronchial carcinoma. This will not be evident if the patient breathes

deeply because it tends to overcome the obstruction.

d- Note abnormal inspiratory movements produced by contraction of the

accessory muscles of inspiration (sternomastoids, scaleni and trapezii).

e- Paradoxical movement of the chest wall (indrawing of chest wall during

inspiration) is seen in patients with double fractures of a series of ribs or

of the sternum (flail chest).

f- Unilateral reduction of chest wall movement occurs in pleural effusion,

empyema, pneumothorax, lung consolidation or collapse and lung or

pleural fibrosis. The affected side, whatever the type of pathology, always

moves less than the sound side.

g- Generalized decrease of chest expansion occurs in asthma, pulmonary

fibrosis, and emphysema and in conditions, which restrict chest

movement as ankylosing spondylitis, systemic sclerosis and obesity.

3- Symmetry of the chest:a. Healthy chest is bilaterally symmetrical with smooth contours.

6

Page 7: pemeriksaan fisik paru

b. Causes of asymmetry: pleural effusion or fibrosis and lung collapse or

fibrosis.

4- Rate and type of respiration:

a- Rate of breathing should be observed without the patient’s knowledge.

Respiratory rate varies in normal individuals between 14 and 18 per

minute. Respiratory rate is increased in pyrexia, acute pulmonary

infections, bronchial asthma and acute pulmonary edema and it is

decreased during sleep and with use of narcotics.

b- In men respiration is usually abdominothoracic (diaphragmatic) while in

women it is thoracoabdominal (costal). A change in type of breathing

may be significant of disease. Respiration is mainly thoracic in

peritonitis, ascites, large ovarian cyst or pregnancy and mainly

abdominal in ankylosing spondylitis, intercostal paralysis, fracture ribs or

pleurisy.

c- Abnormal breathing patterns are :

1) Purse lip breathing: in COPD to decrease collapse of bronchi in

expiration.

2) Bitot’s breathing: sudden deep breathing with apnea in tuberculous

meningitis.

3) Cheyne-stokes breathing: periods of apnea alternating with periods of

hyperventilation that begins gradually. It is observed in respiratory or

heart failure and is probably due to delay in circulation time between

the central and the peripheral chemoreceptors or decreased sensitivity

of the respiratory center to CO2.

4) Kussmaul’s breathing: rapid deep breathing in renal and hepatic failure.

5) Hyperventilation: in meningitis, encephalitis, cerebral hemorrhage,

fevers, hyperthyroidism, anxiety and salicylate overdose.

Hyperventilation causes respiratory alkalosis (due to CO2 wash) with

tetany and drowsiness.

5- Pulsations over the Chest Wall:a- The cardiac pulsations should be examined. In emphysema, the

hyperinflated lungs may obscure all the precordial pulsations except

those on epigastrium.

7

Page 8: pemeriksaan fisik paru

b- The apex may be displaced to opposite side by pneumothorax or pleural

effusion, or drawn to same side by pulmonary collapse or fibrosis or

pleural fibrosis. It is a guide to the position of the mediastinum.

6- Skin and Chest wall:a- Inspect the skin for scars of pleural tapping (in midaxillary or scapular

lines), scars of intercostal intubations (in 5th space in midaxillary line) or

thoracotomy scar.

b- Inspect the chest wall for dilated veins, which indicate superior vena

cava obstruction. If obstruction is proximal to the azygos vein, dilated

veins will be seen all over the chest wall and if obstruction is distal to

the azygos vein, dilated veins is seen mainly around the shoulder.

c- Cutaneous lesions such as skin eruptions, sarcoid nodules (especially in

scar areas), malignant nodules, purpuric spots, bruises or discharging

sinuses should be noticed.

7- Position of the Trachea: (Trill’s sign): a- Trachea is central in its cervical part & it is an indicator of the

mediastinal position.

b- Tracheal displacement is suspected if prominence of the sternomastoid

muscle on one side is present.

c- The trachea may be displaced to opposite side by pneumothorax or

pleural effusion or drawn to the same side by pulmonary fibrosis or

collapse or pleural fibrosis.

8- Lower Intercostal Spaces (Litten’s sign): a- Indrawing of the lower 6 intercostal spaces is normally present in deep

inspiration and in thin persons but when it is present during quite

breathing, it indicates a low flat diaphragm.

b- Contraction of a low flat diaphragm causes pull on the lower intercostal

spaces.

9- Subcostal angle:

a- Normally, the subcostal angle is from 70– 110o.

b- Increased obtuseness indicates gradual increase in intrathoracic or intra-

abdominal pressures and increased acuteness indicates abnormal

protrusion of the sternum as in pectus excavatum or emphysema.

Page 9: pemeriksaan fisik paru

PALPATION

1- Form of the chest : Diameters of the chest are measured by the pelvimeter.

The sternum and ribs should be palpated for any masses. It is important to

examine the vertebral column by passing your fingers (the thumb and index

fingers) along the lateral borders of the spine from above downwards to see if

there is kyphosis, scoliosis or kyphoscoliosis. Scoliosis may be acquired

(secondary to lung or pleural diseases where the curve of spine is towards the

diseased side) or congenital (curve of spine is towards the healthy side).

2- Trachea : a- Position of the trachea is determined by thrusting the tip of the index

finger gently into the suprasternal notch and noticing the resistance on

each side of the trachea, the side with least resistance indicates that the

trachea is shifted to the other side.

b- Normally, trachea is central in its cervical part and slightly shifted to the

right in its intrathoracic part, this shift is not felt clinically.

c- A downward movement of the trachea and larynx during inspiration,

detected by thumb and index fingers on the sides of the thyroid cartilage,

is felt in COPD patients due to contractions of the low flat diaphragm.

d- Tracheal tug (downward pull on the trachea and larynx during systole) is

felt in cases of aortic aneurysm.

3- Local tenderness : Search for local tenderness by superficial palpation of the chest while

looking at the patient’s face to see if there is pain at special areas.

Subcutaneous emphysema is recognized by the crackling sensation.

4- Tactile vocal fremitus (TVF): a- This sign detects vibrations transmitted to the hand from the larynx.

While putting palm of the same hand on the chest in identical areas on

the both sides in turn, the patient is asked to say 44 in Arabic.

b- Pathologically, vocal fremitus is diminished when a bronchus is blocked

as in tumors and in pleural effusion or pneumothorax, which damps

down vibrations.

c- Increased vocal fremitus occurs when vibrations are better conducted as

in cases of:

9

Page 10: pemeriksaan fisik paru

i- Lung consolidation as in pneumonia.

ii- Consolidation collapse with a patent bronchus.

iii- A large cavity or cavity surrounded by consolidation.

iv- At upper level of a pleural effusion posteriorly because the

collapsed lung floats on fluid and becomes in close contact

with trachea and chest wall.

v- In tension pneumothorax because the lung is collapsed totally and

transmission of vibrations is directly from the trachea.

(1) (2) (3) (4) Suprascapular Upper interscapular Lower interscapular Subscapular

Steps in estimation of TVF posteriorly, note do each step on both sides in turn

5- Movements of the chest wall:a- Respiratory movements are compared on infraclavicular, mammary

areas, inframammary, suprascapular, interscapular, scapular and

infrascapular areas.

b- Hands are put (with fingers directed towards clavicles) to compare

movements of the infraclavicular areas. For movements of the

suprascapular areas hands are put also with the fingers directed upwards.

10

Page 11: pemeriksaan fisik paru

c- Grasping the sides of the chest with the outstretched thumbs near the

middle line and asking the patient to take a deep breath examine

movements of the mammary, inframammary and infrascapular areas.

d- Unilateral reduction of chest wall movement occurs in pleural effusion,

pneumothorax, empyema and in pulmonary consolidation and collapse.

In bronchial asthma, emphysema and diffuse pulmonary fibrosis

movements of the chest wall are symmetrically reduced (in the first two

cases due to over inflation of the lungs and in the last case the

movement is restricted by the less distensible lungs).

6- Palpable adventitious sounds:

a- Palpable pleural rub may be present in the lower axillary or

infrascapular areas.

b- Palpable rhonchi may be present in asthmatic patients.

11

Page 12: pemeriksaan fisik paru

7- Pulsations:a- The hand should be placed on each side of chest to avoid overlooking

dextrocardia. The apex, left parasternal 3rd and 4th spaces, pulmonary,

aortic and epigastric areas should be palpated for pulsations.

b- Pulsations in pulmonary area indicate pulmonary hypertension or

pulmonary artery aneurysm. A palpable pulmonary component of the 2nd

heart sound “diastolic shock” is present in pulmonary hypertension.

PERCUSSION

1- Percussion is setting up artificial vibrations in a tissue by means of a sharp

tap with the fingers. The middle finger of the left hand is placed in close

contact with the chest wall and a blow is made on the second phalanx with

the middle finger of the right hand. The striking finger must be kept at right

angle to the other finger and wrist movement makes striking and the finger

must be lifted immediately to avoid damping vibrations.

2- Usually percussion of the chest is light percussion except at the back (a large

mass of tissue) or on determination of the upper border of the liver

anteriorly.

3- Percussion proceeds from resonant to dullness and parallel to the percussed

border (except in Kronig’s isthmus where it proceeds from dullness to

resonance).

4- Normal resonance is found over lung tissue, hyperresonance is found in

emphysema and pneumothorax and tympany is found over the stomach.

Normal dullness is found over solid viscera such as the liver and the heart,

impaired note is found over consolidated or collapsed lung and stony

dullness is found in cases of pleural effusion.

5- Percussion note should be compared on both sides of chest as follows:

a- Anteriorly:

i- Clavicles.

ii- From 1st intercostals space to upper border of liver on right and to

the 6th intercostal space on the left side in midclavicular line.

iii- Percussion may be done also in the anterior axillary line.

b- Axillae: From 4th to 7th intercostals spaces in the midaxillary line.

12

Page 13: pemeriksaan fisik paru

c- Posteriorly:

i- Kronig’s isthmus.

ii- Suprascapular area.

iii- Interscapular areas.

iv- Scapular areas.

v- Infrascapular areas down to the 11th rib or 12th thoracic spine.

6- We start percussion by determining the upper border of the liver in the

midclavicular line then comparative percussion on both sides of chest (each

side in turn space by space) in midclavicular, midaxillary and scapular lines.

7- On reaching upper border of the liver, we fix the finger and ask the patient to

take a deep breath and then we repercuss again to see whether the diaphragm

is mobile or not (tidal percussion). After finishing tidal percussion, and the

finger is still in place, we percuss lightly to see lung encroachment on liver

dullness (hyperinflation or emphysema).

8- During percussion of back, on reaching level of the diaphragm, we do tidal

percussion to detect diaphragmatic mobility on each side. Tidal percussion

differentiates between supra and infradiaphragmatic dullness and detects

diaphragmatic paralysis.

9- If there is dullness at any line we do shifting dullness to detect any fluid level

(hydropneumothorax) and we repeat it in three planes to see if it is localized

or not (while sitting in midclavicular line and in the midaxillary line and

while lying flat).

10- Bare area of the heart, normally dull by light percussion, becomes

resonant in emphysema and left sided pneumothorax. When the heart is

enlarged or in pericardial effusion the size of the dullness increases.

11- Dullness in Traube’s area may be due to:

a- Left pleural effusion.

b- Left basal consolidation.

c- Enlarged left lobe of the liver.

d- Ascites.

e- Splenomegaly.

f- Full stomach and gastric carcinoma.

13

Page 14: pemeriksaan fisik paru

12- Increased resonance of Traube’s are may be due to:

a- Left basal collapse.

b- Pneumoperitoneum.

c- Cirrhotic shrunken liver.

d- Splenectomy.

e- Dilatation of the stomach.

AUSCULTATION1- Normal breath sounds are generated by turbulence of air in the large airways.

They are composed of two elements: the bronchial and the vesicular

elements.

2- Normally, expiration is longer than inspiration, with inspiration/expiration

ratio of 1:1.33, but clinically inspiration is heard longer than expiration

14

Page 15: pemeriksaan fisik paru

because flow of air is turbulent (active process) while it is laminar in

expiration (passive process).

3- Auscultation determines:

a- Equality of Breath Sounds.

b- Intensity of Breath Sounds: Decreased in emphysema and in bronchial

obstruction.

c- Character of the Respiratory sounds:

1. Vesicular breathing: inspiration longer and expiration nearly

inaudible.

2. Bronchial breathing: inspiration= expiration with a gap in-between.

i- Ordinary bronchial: over trachea and in massive

effusion.

ii- Cavernous: over large cavities.

iii- Tubular: in pneumonic consolidation.

iv- Amphoric: in tension pneumothorax.

3. Bronchovesicular: Normally occurs near lung roots behind & in upper

lobes near middle line anteriorly (inspiration=expiration without gap).

d- Vocal resonance:

a. Quantitative changes:

i. Increase: bronchophony and pectoriloquy. Vocal resonance is

examined for by asking the patient to say 44 in Arabic in loud

voice and then to whisper it to detect for whispering

pectoriloquy. The presence of whispered pectoriloquy over the

spinous process of the 4th, 5th and 6th thoracic vertebrae in adults

& over the first 2 or 3 thoracic spines in infants is called

D’Espin’s sign. Bronchophony and whispering pectoriloquy are

heard in the same instances with bronchial breathing.

ii. Decrease: as in pleural effusion and pneumothorax.

b. Qualitative changes: Egophony: It is a peculiar form of vocal

resonance which is heard at the upper limit of pleural effusion

posteriorly. It is detected by asking the patients to say “A” which will

be heard as “E”.

e- Adventitious sounds:

15

Page 16: pemeriksaan fisik paru

a. Rhonchi: Sibilant (high pitched) and sonorous (low pitched). They are

caused by vibrations of the walls of narrowed airways and are more

evident during expiration.

b. Crepitations:

i. Coarse: They are mainly audible during inspiration and are

usually due to increased secretions resulting from chronic

bronchitis or bronchiectasis. Coarse bubbling crepitations occur

in bronchopleural fistula. They may vary from breath to breath

and be modified or abolished by coughing.

ii. Fine: They represent the opening of a small airway previously

closed (or opening of collapsed alveoli). They are most

numerous during the second half of inspiration and are not

influenced by cough. Such crackles are heard in pulmonary

fibrosis & edema, allergic alveolitis, cystic fibrosis, miliary

tuberculosis, pneumonic consolidation (especially as resolution

begins) and over infarcted lung. Post-tussive crepitations may

also be heard in cases of pulmonary tuberculosis.

c. Pleural rub: It is a coarse leathery sound that tends occurs in the same part of the

respiratory cycle (during both inspiration and expiration). It is not altered by

cough. The intensity of pleural rub is often increased by deep breathing and by

firm pressure of the stethoscope. Pleural rub is distinguished from pericardial rub

by its disappearance on holding breath.
