<70% of expected
Give an example of an inhaled low-dose corticosteroid that might be given in asthma treatment
Beclomethasone
Give an example of a LABA that might be given in asthma treatment
Salmeterol
Recall the steps of management for chronic asthma
SABA SABA + inhaled steroid LABA + inhaled steroid \+ LKT agonists Oral steroid
Recall the PEF indicative of each different severity of asthma
50-75% = moderate 33-50% = acute-severe <33% = life-threatening
Recall the management of acute asthma
Oxygen Nebulised salbutamol and ipratopium bromide Oral prednisolone IV hydrocortisone --> IV MgSO4 --> IV Aminophylline --> ITU and intubation

Malignancy
Atrial myxoma
Infective endocarditis
Recall 4 GI causes of clubbing
Malignancy
IBD
Coeliac
Cirrhosis
Which genetic disorder can cause COPD?
Alpha-1 anti-trypsin
Recall the steps of management of COPD (not an acute exacerbation)
- SABA/SAMA
- Add LABA/LAMA
- LABA + LAMA OR LABA + inhaled corticosteroid
- LABA + LAMA + inhaled corticosteroid
Give an example of a SAMA and a LAMA
SAMA: ipratropium bromide
LAMA: tiotropium
What is symbicort?
Combination of LABA and inhaled corticosteroid
What are COPD patients routinely vaccinated against?
Pneumococcus
Influenza
How does management of an acute exacerbation of COPD and asthma differ?
- Initial IV hydrocortisone dose is 200mg in COPD and 100mg in asthma
- Step 2 in asthma is IV MgSO4, but in COPD = IV amoxicillin
- Step 4 in asthma = ITU and intubation, in COPD = BiPAP non-invasive ventilation

Amiodarone
What would be seen on general inspection in ILD?
Clubbing
What would be heard on auscultation of the lungs in ILD?
Bi-basal, fine inspiratory crepitations
In what sort of lung disease might ground-glass opacification be seen on CT?
ILD
What would lung function tests reveal in ILD?
An obstructive pattern to results
To which group of diseases does asbestosis belong?
Pneumoconiasis
What respiratory disease do people who keep pigeons tend to get?
