Design outcomes

Primary

Measure	Time frame
To assess Peak airway pressure in both groupsTimepoint: To assess Peak airway pressure in both groups	—

Secondary

Measure	Time frame
To assess OLP (Oropharyngeal leak pressure) in both groups after intubation, after pneumoperitoneum, and after Trendelenburg position. 2)To compare the Respiratory variables ETCO2 (End tidal carbon dioxide) ,PIP(Peak inspiratory pressure, Pmean(Mean airway pressure, Cdyn (compliance dynamic), Respiratory rate. 3)To compare the intraoperative hemodynamic vitals (PR, SPO2, MAP) 4) To assess complications like, Trauma to mouth, lip tongue, blood staining at removal, sore throat, staining of device, dysphonia, hoarseness of voice Timepoint: During surgery and upto 24hr	—
