34
Q

When are the accessory inspiratory muscles used?

A

Accessory inspiratory muscle used if adequate pulmonary ventilation cannot be achieved by normal inspiratory efforts when there is gross overdistension of the lungs:

  • Advanced emphysema
  • Attack of severe asthma
  • Stridor due to laryngeal/ tracheal obstruction
35
Q

When are the accessory expiratory muscles used?

A

Accessory expiratory muscles used the elastic recoil of the lungs is insufficient to empty the alveoli or if there is expiratory airway obstruction:

  • Some patients with emphysema
  • Some cases of chronic bronchitis
  • Asthma
36
Q

How do patients with expiratory obstruction present?

A

Some patients will stand and grasp a table so that they fix the shoulder girdle and use latissimus dorsi to augment the expiratory effort

37
Q

Why does pursed lip breathing present in emphysema?

A
  • Pursed lip breathing is a a breathing technique used to control shortness of breath
  • It allows pressure to be maintained in the alveoli, preventing their collapse and limiting trapped air to improve ventilation
38
Q

Why is there barrel chest in emphysema?

A

Barrel chest occurs due to loss of elastin in the lung allows the chest wall to expand

39
Q

What is the significance of tracheal position in emphysema?

A

Tracheal position is used to detect mediastinal displacement

40
Q

Which conditions cause tracheal deviation away from affected side?

A
  • Tension pneumothorax
  • Large pleural effusion
41
Q

Which conditions cause tracheal deviation towards the affected side?

A
  • Lung/ lobar collapse
  • Pulmonary fibrosis (particularly upper lobe)
42
Q

Describe the underlying pathophysiology of lung/lobar collapse

A
  • Occurs following obstruction of a bronchus
  • Gas is resorbed from the lung parenchyma distal to the obstruction
  • Lung collapses (volume reduction and negative mass effect)
43
Q

Which areas on the chest are expected to be dull on percussion in a normal individual?

A

Due to density of structures:

  • Liver
  • Heart
  • Clavicle
  • Sternum
44
Q

In COPD, why are normal areas of dullness absent?

A

On percussion, there is decreased hepatic and cardiac dullness due to hyperinflation of the lungs as it pushes the liver down and increases air in the cavity (hyperresonance)

45
Q

Which lobes of the lungs are best auscultated over the anterior chest?

A
  • Right upper lobes
  • Right middle lobes
  • Left upper lobes
46
Q

Which lobes of the lungs are best auscultated over the posterior chest?

A
  • Right lower lobes
  • Left lower lobes
47
Q

What are the three different types of breath sounds?

A
  • Vesicular
  • Bronchial
  • Tracheal
48
Q

Describe the location, quality and pitch of tracheal breath sounds

A
  • Location: trachea
  • Quality: loud, harsh, hollow
  • Pitch: higher
49
Q

Describe the location, quality and pitch of bronchial breath sounds

A
  • Location: manubrium
  • Quality: loud, less harsh, hollow
  • Pitch: higher
50
Q

Describe the location, quality and pitch of vesicular breath sounds

A
  • Location: peripheral lung
  • Quality: softer (audible gap between inspiratory & expiratory phase sounds)
  • Pitch: low
51
Q

What is lung consolidation?

A
  • Lung consolidation is a solidification of lung tissue due to the filling of the lungs with liquid and solid material
  • These liquids replace the air normally present in alveoli
52
Q

What is the commonest cause of lung consolidation?

A

Pneumonia

53
Q

What pathological processes may lead to consolidation?

A

Pneumonia – bacterial infection in alveoli produces an inflammatory process and exudate accumulates in alveoli

54
Q

In lung consolidation, what is heard over the lung fields during ausculation?

A

Bronchial breathing

55
Q

Why are bronchial breath sounds heard over an area of pneumonic consolidation?

A
  • If bronchial breath sounds are heard over the chest, it suggests consolidation/fibrosis
  • Sounds of bronchial breathing are generated by turbulent air flow in the large airways, and are usually heard over the trachea/manubrium in healthy patients
56
Q

What are the different types of abnormal breath sounds?

A
  • Discontinuous (non-musical):

I. Crackles

II. Pleural friction rub

  • Continuous (musical):

I. Wheezes

II. Stridors

57
Q

What are the causes of pleural friction rub?

A
  • Pleurisy
  • Pulmonary infarction (due to PE)
58
Q

What are respiratory crackles?

A

Respiratory crackles are abnormal breath sounds due to the snapping open of airways / fluid in airways)

59
Q

What are the two types of respiratory crackles and when are they seen?

A
  • Fine crackles – early and fine in idiopathic pulmonary fibrosis, consolidation and LVF
  • Coarse crackles – early and coarse in COPD, bronchiectasis (may reduce after coughing)
60
Q

What are the four possible sounds heard on percussion?

A
  • Resonant → normal finding
  • Dull → increased tissue density
  • Stony dull → pleural effusion
  • Hyperresonant → decreased tissue density
61

65
Q

Which structures in the thorax are well-endowed with pain fibres and which are not?

A
  • Well-endowed: parietal pleura
  • Poorly endowed: visceral pleura
66
Q

What is the significance of pain fibres with reference to how patients experience pain in respiratory conditions?

A
  • Pathology involving the parietal pleura is very sharp, well-localised pain which is worse on inspiration and coughing
  • Pathology arising in the lung itself is diffused and poorly-localised pain
67
Q

Why does the trachea shift in tension pneumothorax?

A

Increased pressure of air in the pleural space pushes the trachea away from the lesion

68
Q

In 4 steps, explain why hypotension often presents with tension pneumothorax

A

Pushed mediastinum obstructs great vessels in lung hilum

⇒ Decreased venous return from the pulmonary artery

⇒ Decreased cardiac output

Hypotension
