The aim of this study is to evaluate the effect of high-flow nasal cannula oxygen administration on apnea in patients undergoing general anesthesia with rigid bronchoscopy compared with standard anesthesia methods.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

100 % of oxygen at 70 L / min through Optiflow ™ (Fisher and Paykel Healthcare Limited, Auckland, New Zealand)
Device: Optiflow ™
standard anesthesia
supply of 100 % of oxygen at 70 L / min through Optiflow ™ (Fisher and Paykel Healthcare Limited, Auckland, New Zealand) plus standard oxygen supply through rigid bronchoscope during apnea period.
the lowest oxygen saturation
the lowest value of oxygen saturation measured percutaneously at extremity.
Time frame: apnea period during the rigidbroscopic procedure/surgery
Hypoxia occurs the first time
Time frame: intraoperative (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)
End-tidal carbon dioxide partial pressure
Time frame: Intraoperative (end-tidal CO2 partial pressure after 3 consecutive breaths after intubation or insertion of laryngeal mask following end of apnea)
Arterial oxygen / carbon dioxide partial pressure
Time frame: shortly before start of apnea (within 30 seconds)
Arterial oxygen / carbon dioxide partial pressure
Time frame: shortly after end of apnea (within 30 seconds)
hypoxemia related surgical interruptions
Time frame: 4) hypoxemia related surgical interruptions during apneic period
