The study compares the safety of using pressure controlled ventilation with a positive end-expiratory pressure (PEEP) during induction of general anaesthesia immediately after apnoea to a standard method starting ventilation manually without PEEP immediately after apnoea.
Using a continuous positive pressure (CPAP) during preoxygenation, followed by pressure controlled ventilation with PEEP after apnoea during induction of general anesthesia, might offer several benefits but safety issues needs more investigation. This study compares the safety of using pressure controlled with PEEP during induction of general anesthesia immediately after apnoea to a standard method starting ventilation manually without PEEP immediately after apnoea.

The intervention consists of starting ventilation after apnoea during induction of general anesthesia with pressure controlled ventilation with PEEP instead of manually without PEEP.

Number of breaths until return of CO2.
When starting ventilation after apnea the number of breaths given until the return of CO2 is at least 1.3 kPa at a respiratory frequency of 10 per minute.
