A structured approach to the seriously ill or injured child can rapidly optimise their outcome.
Estimation of weight in children is inaccurate and they should be weighed as soon as stabilised. The PAWPER tape allows for consideration of body habitus when estimating weight and can be used as an alternative to the formulae provided (in diagram below).
The following is a diagrammatic overview derived from an advanced paediatric life support approach.

To optimise oxygen delivery:
- Oxygen, high flow, 15 L/minute via facemask with reservoir bag or 6–10 L/minute via head box.
- If oxygen saturation < 92% or PaO2 < 80 mmHg despite maximal oxygen supply, consider providing additional respiratory support.
