A 69-year-old morbidly obese man presents to a rural emergency department with 2 days of worsening dyspnoea. He has been treated for respiratory sepsis with 3 L normal saline plus IV ceftriaxone and azithromycin according to local guidelines. The local doctor requests retrieval to a tertiary hospital because there is no HDU facility and asks how to optimise him while waiting for the retrieval team.

He is cooperative but finds the mask uncomfortable, and fixed-wing transfer will take 2 hours including transfers. Complete the table of relative risks and benefits for respiratory support options.
