>0.5, the effusion is an exudate
This is different to protein G
<30G- transudative
>30- exudative
What are indications for long term oxygen therapy in a patient with COPD?
very severe airflow obstruction (FEV1 < 30% predicted). Assessment should be ‘considered’ for patients with severe airflow obstruction (FEV1 30-49% predicted)
cyanosis
polycythaemia
peripheral oedema
raised jugular venous pressure
oxygen saturations less than or equal to 92% on room air
Management for symptomatic pneumothorax is:
1st line- FNA
2nd line- chest drain
When is a chest drain preferred over FNA?
Assess for high risk characteristics:
haemodynamic compromise (suggesting a tension pneumothorax)

bilateral pneumothorax

What are Interstitial Lung Diseases?
These are conditions characterised by inflammation and fibrosis of the lung parenchyma.
Fibrosis involves replacement of the lung elastic tissue to the non functional fibrotic tissue

Management:
Avoid exposure to coal dust and other respiratory irritants (e.g. Smoking).
