NCT02920879

Brief Summary

This study investigates airway effects of PEEP during maskventilation at anesthesia induction. Four patient groups will be ventilated with different PEEP and driving pressures to evaluate time to open airway after start of positive pressure maskventilation during anesthesia induction.

Outcome Measures

Primary Outcomes (1)

  • Time to open airway

    Time to open airway depending on ventilatory settings

    20 minutes

Study Arms (4)

0 CPAP/ 0 PEEP, driving pressure 10

OTHER

Patients will be preoxygenated with a CPAP-level of 0 cmH2O and after anesthesia induction, mask-ventilated with ZEEP and a driving pressure of 10 cmH2O./PEEP-level, driving pressure

Procedure: PEEP-level, driving pressure

0 CPAP/ 0 PEEP driving pressure 20
