High flow oxygen results in better oxygenation in emergency cases needing rapid sequence induction for anaesthesia. Secondary outcome measure is time for any desaturation.
The investigators intend to do the study using high flow oxygen for all emergency cases needing rapid sequence induction. As part of the study the Investigators will measure the oxygen levels in the blood gas sample of the patient and the heart rate of anesthetist in charge of the airway management. After the airway is secured the time for desaturation will be noted.

RECRUITINGOxygen levels in blood gas sample
Oxygen levels in blood gas sample after the airway is secured
Time frame: intraoperative
time to desaturation
after airway is secured time will be noted for oxygen levels to fall to 92% before the ventilation is started.
Time frame: intraoperative or 10 minutes after intubation
heart rate of anaesthetist performing the intubation
Time frame: During the process of induction of anaesthesia and intubation upto 5 minutes post intubation
