Inspection
A. Position of the patient• sitting position (cardiac disease, COPD)
• sitting position leaning on hands (an attack of asthma)
• unable to lie flat comfortable (cardiac diseases, pulmonary edema, diseases with remaining sputum)
• preference for lieing one side only (local pathologic processes – lung abscess)

Inspection
THORACIC DEFORMITIES: bilateral or unilateral
Barrel chest – the chest wall held in hyperinflation
- dilatation in lateral size of the chest (A-P diameter can be greater than the lateral)
- ‘pump handle’ – up and down movements of the ribs
- poor expansion
- emphysema, in asthma

Pectus carinatum – pigeon breast
- secondary to chronic respiratory diseases in childchood, may
be caused by rickets ( in malnutrition)

Inspection
ABNORMALITIES OF RESPIRATORY RATE AND RYTHM
Bradypnea – an abnormal slowing of respiration (central nervous system diseases, caused by drugs)
Tachypnea – an abnormal increase of breathing frequency (severe pain, chronic pulmonary or cardiac diseases, anxiety)
Apnea – the temporary cessation of breathing
Hyperpnea – an increased depth of breathing (metabolic acidosis)

Palpation
E. Tactile Fremitus
• the vibrations produced by the patient’s speaking are transmited the lung tissue and felt by hand
• normal fremitus is symetric in the same parts of the chest
• two methods of examination

Palpation
CHANGES IN TACTILE FREMITUS
Rhonchal fremitus - exudate in the trachea
Increased fremitus - lung consolidation with patent bronchus
Decreased fremitus - unilateral - bronchial obstruction, air or fluid in pleural space
bilateral - edematous chest wall chest wall thickening

Percussion
Dirrect percussion
used very unfrequently, only for percussion the clavicle
![Page 21: EXAMINATION OF RESPIRATORY SYSTEM - … of the... · the most common technic of the chest examination . ... laryngospasm, laryngeal edema, a ... COPD, diseases with bronchospasm,](https://reader031.fdocuments.in/reader031/viewer/2022022422/5a8ecf4d7f8b9ac87a8dd099/html5/thumbnails/21.jpg)
Percussion
Indirrect percussion
comparing and topographic
Normal percussion note is resonant over all of the lungs except over
organs (heart, liver), where dullness is detected.

Percussion
CHANGES IN PERCUSSION NOTE
Hyperresonance - emphysema
Impaired resonance - lung consolidations
Dullness - pulmonary infiltrations, pleural thickening
Flattness - pleural effusion

Auscultation
Auscultation
the most common technic of the chest examination
![Page 24: EXAMINATION OF RESPIRATORY SYSTEM - … of the... · the most common technic of the chest examination . ... laryngospasm, laryngeal edema, a ... COPD, diseases with bronchospasm,](https://reader031.fdocuments.in/reader031/viewer/2022022422/5a8ecf4d7f8b9ac87a8dd099/html5/thumbnails/24.jpg)
Auscultation
The breath sounds are produced by the air moving
through the tracheo-bronchial tree during respiration
- the turbulence in the large airways creates vibrations
which are transmitted through the lungs to the chest wall
It is never acceptable to listen through clothing.
The stethoscope must be in contact with the skin !!!
![Page 25: EXAMINATION OF RESPIRATORY SYSTEM - … of the... · the most common technic of the chest examination . ... laryngospasm, laryngeal edema, a ... COPD, diseases with bronchospasm,](https://reader031.fdocuments.in/reader031/viewer/2022022422/5a8ecf4d7f8b9ac87a8dd099/html5/thumbnails/25.jpg)
Auscultation
Patient is seated upright with shoulders rotated forward in a
relaxed manner
- ask the patient to breathe in & out through his mouth
deeply, but not too fast
- listen in sequence over the chest (anterior, lateral, posterior chest wall) start at the apices than move down to the bases
- remember to compare corresponding areas on each side

Auscultation
Tracheal breath sound – very loud, high-pitch
Bronchial breath sound - over trachea and main bronchi
Vesicular breath sound - over most of the lungs – the
inspiratory phase predominate

Auscultation
ABNORMAL BREATH SOUNDS
1. Absent (decreased) breath sound:• generalized reduction in breath sound – thick chest wall, obesity
• no aerated lung under the area being examined or an intrapleural process blocking the transmission of sounds
- airway obstruction: foreign body aspiration, endobronchial tumors laryngospasm, laryngeal edema, a mucus obstruction a bronchus
- sugical removal of lung tissue: lobectomy, pneumonectomy
- pleural abnormalities: pneumothorax, pleural effusion

Auscultation
VOCAL RESONANCE - a voice sound heard over the normal lung (ask the patient to say ‘99’ or count ‘1,2,3’ while auscultating him) abnormal voice sounds• bronchophony: increased clarity of the spoken word - heard over areas
where alveoli are filled with fluid (liquid & solid medium transmits sounds better than an air-filled medium) – consolidations, athelectasis, partial compression of a bronchus by tumor
• whispered pectirology: increased transmission of the whispered word to the chest wall (often heard before other abnormal lung sounds)
• egophony: modified form of bronchophony (heard above upper level of plural effusion)

Auscultation
2. Bronchial breath sounds over the peripheral lung
• increase in tissue lung density: consolidation – pneumonia, lung abscess, dense fibrosis

Auscultation
ADDED (ADVENTITIOUS) SOUNDS can be heard during auscultation in addition to the normal breath sounds
1. Wheezes – high-pitched, musical sounds • largely occuring on expiration, sometimes on inspiration
• are due to localized narroving within the bronchial tree ( smooth muscle contraction, inflammatory changes in the chest wall)
• asthma, COPD, diseases with bronchospasm, vocal cord paralysis

Auscultation2. Cracles - (older term - rales and crepitations)
• short, discrete, non-musical sounds,
• heard mostly during inspiration,
• caused by opening of collapsed alveoli
• may be described as early or late, depending on when they are heard during inspiration
(early pulmonary edema, atelectasis, resolving pneumonia)
• coars– low-pitched, are related to larger airways
louder than fine rales, are rarely heard on expiration

Auscultation
3. Ronchi – lower -pitched sound, more sonorous• caused by mucus plugging and poor movement of airway secretion
(COPD, bronchiectases, cystic fibrosis)• heard during both phases of respiration
4. Pleural friction rub – low-pitched, loud sound, • result of rubbing of pleural surfaces together, • sounds the same as rubbing the thumb and index finger to one’s
ear, • heard during both phases of respiration • inflammation of the pleura

Extrathoracic signs of lung diseases
Cyanosis
• a blue discoloration of the skin, nail beds and mucus
membranes
• cause: elevated levels of reduced hemoglobin >5g/dL
![Page 34: EXAMINATION OF RESPIRATORY SYSTEM - … of the... · the most common technic of the chest examination . ... laryngospasm, laryngeal edema, a ... COPD, diseases with bronchospasm,](https://reader031.fdocuments.in/reader031/viewer/2022022422/5a8ecf4d7f8b9ac87a8dd099/html5/thumbnails/34.jpg)
Extrathoracic signs of lung diseases
Cyanosis:
• central - advanced pulmonary diseases, congenital heart diseases
with right-to-left shunting
• peripheral – is seen only in the extermities, ears, and lips and is caused by a reduction in the systemic blood flow resulting from a decreased cardiac output
![Page 35: EXAMINATION OF RESPIRATORY SYSTEM - … of the... · the most common technic of the chest examination . ... laryngospasm, laryngeal edema, a ... COPD, diseases with bronchospasm,](https://reader031.fdocuments.in/reader031/viewer/2022022422/5a8ecf4d7f8b9ac87a8dd099/html5/thumbnails/35.jpg)
Extrathoracic signs of lung diseases
Clubbing
• proliferative change in soft tissues of the digits
• loss of normal angle at base of nail
• ethiology is unknown: probably caused by increased blood flow through multiple arteriovenous shunts
• COPD, lung cancer, cystic fibrosis
