Q

What is the pathophysiology of a cough?

A

Irritation of Mechanoreceptors stimulates the RAS, SAS and C fibres to transmit information down the vagus nerve to the nucleus tractus solitaris in the medulla oblaganta. The NTS also receives input from inflammatory cytokines from mast cells. The NTS sends signals down efferent fibres to induces the action of the contraction of the respiratory muscles to expel air.

Q

Why do ACE inhibitors cause coughing?

A

ACE inhibitor drugs allow increased levels of the pro-inflammatory mediators bradykinin and substance P which stimulate the nucleus tractus solitaris to induce cough.

23
Q

What should be assessed in haemoptysis?

A

Volume of blood
Frequency of coughing up blood

24
Q

What is wheeze?

A

High pitched noise generated during expiration due to obstruction of airways. This is common in conditions such as asthma and COPD.

25
Q

What is stridor?

A

High pitched noise generated during inspiration due to obstruction of airways.

This occurs in whooping cough, epiglottitis, laryngeal tumour and laryngeal oedema.

26
Q

How should chest pain be assessed?

A

Site of pain.

27
Q

What does pleural pain indicate?

A

Pleuritic pain is sharp chest pain when breathing in due to inflammation of pleura.

28
Q

What does the site of retrosternal pain indicate?

A

Pain located generally behind the sternum.
-> If it is constant and gets worse, even without exertion, indicates mediastinal tumour.
-> Upper retrosternal pain indicates inflammation of the trachea/tracheitis
-> GI reflux when accompanied with burning sensation

29
Q

What does bony pain indicate in the chest?

A

Rib metastasis
Costachondritis

30
Q

What does spinal root pain indicate?

A

Radiculopathy, where there is injury to the spinal nerve root as it leaves the spine, causing pain anywhere in the body, like the chest.

31
Q

How can we assess a patient with respiratory symptoms?

A

Inspection
Percussion
Palpation
Auscultation

32
Q

What do we assess in inspection?

A

Peripheral cyanosis
Finger clubbing
Oedema
Use of accessory muscles, indicating respiratory distress
Muscle wasting
Respiratory rate
Dilated veins

33
Q

What does clubbing indicate?

A

Hypoxaemia
Malabsorption from digestive issue

34
Q

What is pectus carinatum?

A

Chest wall protrudes out and anteriorly AKA pigeon chest.

35
Q

What is pectus excavatum?

A

Ribs and sternum grow inwards and create a dent in the chest AKA funnel chest.

36
Q

What signs do you look for in palpation?

A

Reduced expansion
Position of the trachea
Mediastinal shift which occurs due to:
->pleural effusion
->Pulled towards region of lung collapse or fibrosis

37
Q

What do you assess in palpation?

A

Cricosternal distance between the cricoid cartilage and the suprasternal notch. This should be 3-4cm and is reduced in hyperinflation.

38
Q

What condition is caused by hyperinflation?

A

COPD
Chronic asthma

39
Q

What are the signs of hyperinflation?

A

Barrel chest
Loss of liver and cardiac dullness

40
Q

What are the signs of percussion that should be assessed?

A

Compare the two sides which should both be resonant.

41
Q

F

A
42
Q

What is the cause of stony dullness?

A

Pleural effusion due to greater fluid in pleural space reducing air resonance for percussion.

43
Q

What is the cause of hyper-resonance?

A

Pneumothorax
-> Collapse of the lung which causes air to fill between the lungs and chest wall that limits expansion, increasing air causing louder percussion.

44
Q

What signs should be assessed in auscultation?

A

Vesicular breath sounds that are soft and low-pitched.
Vocal fremitus
Whispering

45
Q

What causes diminished vesicular sounds?

A

Pneumothorax
Pleural effusion

46
Q

What can result in absent breathing sounds?

A

Pneumothorax
Lung collapse
Effusion

47
Q

What causes low-pitched and ‘sticky’ bronchial breathing on auscultation?

A

Consolidation of the lungs, where the air-filled spaces are filled with inflammatory exudate in the alveoli. This occurs due to atelactasis, infection, lung cancer and pulmonary haemorrhage.

48
Q

What is amphoric breathing?

A

Breath sounds over a cavity

49
Q

What causes crackles when breathing?

A

Typically occurs on inspiration
-> if they clear when coughing,it is due to larger airway secretions

50
Q

What causes coarse crackles?

A

Pneumonia
Bronchieactasis

51
Q

What are the features found in consolidation?

A

Air filled spaces of the lungs become filled with material like fluid or pus.

There is dull percussion due to loss of air, increased vocal resonance and air sounds are bronchial breathing which is loud and harsh.

52
Q

What features are found in pleural effusion?

A

On an X-Ray:
There is blunting of the costophrenic angle of the diaphragm
Mediastinal shift to contralateral side
Grey colour of lungs due to fluid
Fluid collection around the diaphragm due to action of gravity.

Examination will show dull, stony percussion and reduced chest expansion, vocal resonance and breath sounds.

53
Q

What features are found in airway obstruction?

A

Chest expansion is symmetrical with wheezing. Otherwise, there is normal breath sounds and percussion.

54
Q

What features are found in pneumothorax?

A

Pneumothorax is when air enters the pleural space and causes lung collapse. Features on X ray shows:
Mediastinal shift to contralateral side
Completely black lung with no sight of vascularisation and dullness of heart border

Examination will show hyper-resonance, reduced breath sounds and reduced chest expansion.

55
Q

What features are found in lung collapse?

A

Atelactasis is collapse of the lung due to compression or airway obstruction. X ray will show:
Mediastinal shift TOWARDS the side of the opacity, where the lung will be grey in colour and not its normal black

Phrenic angle will be higher
Silhouette of the heart will be hazy
