Design outcomes

Primary

MeasureTime frame
Time to attain adequate preoxygenation defined as an end-tidal oxygen concentration(EtO2) of 10% below the inspired oxygen concentration.Timepoint: during pre- oxygenation, before induction of general anaesthesia.—

Secondary

MeasureTime frame
Incidence of atelectasis in the immediate post-operative period using lung ultrasound. Percentage of subjects who required pre-oxygenation for more than 3 minutes to attain the target EtO2 Haemodynamic changes during pre- oxygenation Desaturation during intubation Timepoint: end of surgery—
