Scott Weingart from EMCrit on pre-ox and ap-ox for the emergency RSI.

Fits in well with the talks on safe RSI and hypoxic RSI by me.

Summary:

• Non-hypoxic patient:
  • Pre-ox and Ap-Ox:
    • Non rebreather mask (NRBM) and Nasal cannula (NC), both @ 15L/min
    • or
    • any of the options below
• Hypoxic patient:
  • Pre-ox and Ap-Ox:
    • Bag-valve-mask (BVM)+PEEP (≤15cmH₂O) and NC, both @ 15L/min
    • or
    • ventilator CPAP and NC @ 15L/min
    • and 
    • consider gentle ventilation with BVM+PEEP or ventilator during apnoea
