Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Oropharyngeal leakage pressure (OLP) (cmH2O), this is the ventilation pressure above which a leak in the laryngeal mask becomes apparent. For this, the expiratory valve is closed (40 cmH2O) and switched to manual ventilation. The peak pressure reached until leakage corresponds to the OLP. The measurement is taken 10 minutes after induction of anaesthesia. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expiratory tidal volume (ml) Leakage volume (ml) Maximum minute volume test (16) Maximum ventilation pressure (mbar) Postoperative complaints: Sore throat Hoarseness Dysphagia Soft tissue damage Tooth damage | — |
