结局指标

主要结局

To compare the highest pharyngeal FiO2 with delivered FiO2 .

时间窗: One hour before starting of general anesthesia.

次要结局

To find association between nasal patency & change in FiO2 during HFNO preoxygenation.(Will be done before the patient gets shifted inside the operation theatre at preoperative holding area.)
To find association between set flow rate & change in FiO2 during HFNO preoxygenation.(The flow rate will be increased at increments of 10L upto 60L, each flowrate given during a period of one minute.)
