SABA or SAMA

need to determine if patient has asthmatic features because if they do then can prescribe steroids

25
What criteria suggest a COPD patient has a cross over with asthma?

27
What does Total gas transfer (TLCO) measure?
measures gas transfer from alveoli into lungs (essentially looking at how much oxygen enters RBC)
28
What causes raised TLCO?
asthma pulmonary haemorrhage (e.g. granulomatosis with polyangiitis, Goodpasture's) left-to-right cardiac shunts polycythaemia hyperkinetic states male gender, exercis
29
What causes lowered TLCO?
pulmonary fibrosis pneumonia pulmonary emboli pulmonary oedema emphysema anaemia low cardiac output
29
When do you place a chest tube in patients with effusion?
1) fluid is purulent 2) fluid is clear but pH<7.2
29

29
Management of Acute COPD exaceration
- 5 day course of oral prednisolone if clinical signs of infection ( change in colour of sputum, etc) 1st line - amoxicillin or clarithromycin or doxcycline

40
What to do if WELLS score is <4?
- perform D-Dimer test - positive D-Dimer --> do CTPA - negative D-Dimer --> stop anticoagulation and consider other diagnosis
