Design outcomes

Primary

Measure	Time frame
To compare the incidence of gastric insufflation during pre oxygenation using face mask ventilation in supine and propped up at 15 degree positions by measuring the antral volume using ultrasound. Timepoint: Before and after 3 minutes of preoxygenation	—

Secondary

Measure	Time frame
1.To compare the time taken to reach ETO2 of 90% in both groups. 2.To compare the saturation,rate of rise of peak airway pressure & the ETCO2 between two groups. 3.To compare the incidence of sideeffects like aspiration,nausea,vomitting in both groupsTimepoint: Baseline,1 minute,2 minutes,3 minutes,4 minutes,5 minutes.	—
