Summary
This study compares under controlled conditions if different flow rates affect apnoea time
after induction of anaesthesia and how CO2 clearance is influenced. Furthermore, this study
enables to quantify the effects of increased pCO2 on vital parameters (e.g. blood pressure,
cardiac output, cerebral perfusion, etc.) The investigators will enroll patients undergoing
elective surgery at the University Hospital of Bern, Switzerland.
Once anesthesia has been induced, apnoea will set it. During this period, the investigators
will compare different methods of apnoeic oxygenation for a maximum of 15 or 30 minutes.
Before discharge, an interview will be conducted, assessing complications and patient
satisfaction.
