Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
To compare the highest pharyngeal FiO2 with delivered FiO2 .	One hour before starting of general anesthesia.

Secondary Outcome Measures

Name	Time	Method
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.
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.
