- Primary Outcome Measures
Name Time Method The primary objective is to assess the difference in partial pressure of oxygen, after 3 min of preoxygenation in patients preoxygenated with HFNO vs patients preoxygenated with bag mask ventilationTimepoint: The difference in partial pressure of oxygen will be noted by taking arterial blood sample after three minutes of pre oxygenation
- Secondary Outcome Measures
Name Time Method 1. Difference in partial pressure of oxygen.Timepoint: After intubation;2. Difference in end tidal O2Timepoint: After intubation;3. Incidence of hypoxemic events(SpO2 92%)Timepoint: Number of Events until intubation;4. Tolerability of high flow nasal canula by patients, i.e., if patients request to reduce flow or feeling of dryness, itching etc.Timepoint: Till induction;5.Time taken to successful intubationTimepoint: After Intubation;6. Any complications until following intubation like arrhythmiasTimepoint: After intubation;7. Reoxygenation time defined as the time taken for SpO2 to return to 100% after mechanical ventilation.Timepoint: After initiation of Mechanical ventilation
