How do you manage an acute exacerbation of COPD?
(Patient presents with history of increasing cough, breathlessness or wheeze)
- Brief history - ask about smoking status, exercise capacity
- ABCDE assessment - take bloods and get IV access
- Give O2 via a venturi facemask (blue 2L)- aim for O2 sats 88-92%
- Do an ABG, request CXR to rule out pneumothroax or infection
- Nebulised salbutamol 5mg and ipratropium 500 mcg/ 6 hours driven by air

- If no repsonse, consider NIV.
- Call respiratory reg if no response, if still using accessory muscles despite maximal treatment call DART team as may need intubating
