Q

3 respiratory diseases asso. with clubbing

A

Bronchial carcinoma
Bronchiectasis
Pulmonary fibrosis

2
Q

Cough qualities:

  • Bovine
  • Rattling
  • Muffled wheezing
  • Barking
  • Whooping

Suggestive with what pathologies?

A
  • Bovine: lack of explosive onset > Vocal cord paralysis
  • Rattling: Increased bronchial secretions
  • Muffled wheezing: Airway obstruction
  • Barking = acute upper airway obstruction
  • Whooping = pertussis
3
Q

Wheezing during breathing.

Difference in wheezing between inspiration and expiration?

A

Wheezing = airway narrowing

Wheezing during inspiration/ Stridor = Upper airway obstruction

Wheezing during expiration = Lower airway obstruction

4
Q

Respiratory cause of elevated JVP?

A

Increased right heart pressure: Pulmonary hypertension

5
Q

Explain changes in breath sounds caused by pneumonia/ area of consolidation?

A

Bronchial breath sound: High frequency, with silent pause between inspiration and expiration

Pneumonia/ consolidation causes lung cavities to be filled with fluid or solid&raquo_space; Increase sound transduction > Increase upper airway breath sounds

6
Q

Differentiate Biphasic, early inspiratory, mid-inspiratory and pan-inspiratory inspiratory crackles

A

Biphasic = bronchiectasis (coarse)

Early inspiratory = small airway obstructive diseases (eg. COPD)

Mid inspiratory = pulmonary oedema

Pan-inspiratory = Diffuse fibrosis (fine), pulmonary edema (medium), Pneumonia, lung abscess, TB, COPD secretions (coarse)

7
Q

Differentiate anatomical location related to coarse or fine crackles

A
Coarse = Large airway/ bronchi 
Fine = Small airway/ Bronchioles
8
Q

Changes in vocal resonance in consolidation and pleural effusion compared to normal?

A

Normal = muffled sound, dampened by air-filled lung cavities

Consolidation: Inflammatory exudate and fibrosis transduce sound much better = Increase vocal resonance

Pleural effusion: space between auscultation and lung is increased by fluid = Quieter vocal resonance

9
Q

Differentiate causes of tenacious, purulent, and brown sputum

A

Tenacious - Asthma

Purulent - Bronchial inflammation (infection)

Brown - Intra-alveolar hemorrhage

17
Q

Key difference in sign between tension pneumothorax and pleural effusion

A

Tension pneumothorax = Hyper-resonant on percussion

Pleural effusion = fluid-filled = Stony dull on percussion

  • Crackles

Dx?

A
