About this study

As mentioned above

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Indication of an elective surgery with invasive arterial blood pressure measurement in awake patients
  • written informed consent

Exclusion criteria

  • Emergency surgery
  • Patients with expected difficult airway and indication for an awake fiberoptic intubation and therefore no need of preoxygenation
  • no written informed consent
