The efficacy of oxygen wafting using different delivery devices, flow rates and device positioning.

Background: Oxygen "wafting" provides a non-contact oxygen alternative for uncooperative paediatric patients in the emergency department (ED). The aim of this study was to identify the combination of oxygen delivery device, flow rate and device positioning that delivers the highest concentration of wafted oxygen.

Methods: ED nursing staff were surveyed to determine current oxygen wafting practice.
