Exclusion Criteria:
Patients 7 years or younger who undergo general anesthesia with rigid bronchoscopy
Device: Optiflow
supply of oxygen at 2 L / min/ kg through Optiflow
Hypoxia occurs the first time
The time taken to reach the point at which peripheral oxygen saturation fell below 90 for the first time immediately after the onset of apnea
Time frame: The time taken to reach the point at which peripheral oxygen saturation fell below 90% for the first time immediately after the onset of apnea intraoperatively.
the lowest oxygen saturation
the lowest value of oxygen saturation measured percutaneously at extremity.
Time frame: apnea period during the rigidbroscopic procedure/surgery
Occurence of hypoxic event
Occurence of hypoxic event: Presence or absence of hypoxia(peripheral oxygen saturation fell below 90% ) during rigid bronchoscopy
Time frame: apnea period during the rigidbroscopic procedure/surgery
End-tidal carbon dioxide partial pressure
Time frame: end-tidal CO2 partial pressure after 3 consecutive breaths after intubation or insertion of laryngeal mask following end of apnea during intraoperative period.
