Primary Outcome Measures

Name	Time	Method
Pre-oxygenation group - End-tidal oxygen fraction measured by the end tidal gas analyser on the anaesthetic machine [ After three minutes of pre-oxygenation with high flow humidified nasal oxygenation.];Apnoeic oxygenation group - Lowest oxygen saturation level measured by the pulse oximeter [ Pulse oximetry (oxygen saturation monitor) monitoring will be continuous and this is displayed and recorded continuously. The lowest recorded oxygen saturation during the time from completion of routine pre-oxygenation until 5 minutes after successful tracheal intubation will be the numerical data point recorded.]

Secondary Outcome Measures

Name	Time	Method
Pre-oxygenation group - Comfort level of the standard face mask and the high flow nasal cannuale assessed using a 5-Point Likert Scale.[ At completion of the study protocol]
