Design outcomes

Primary

Measure	Time frame
The primary endpoint is defined by ventilation success according to the criteria listed below. It is assessed over a period of two minutes, during which volume-controlled ventilation is performed. Pressure and flow measurements are recorded using a flow/pressure sensor (evaluation unit SEK-SFM3300-D, Sensirion®/Nicolay®). Mechanical ventilation is provided using the Dräger Oxylog 300 VE ventilator (Drägerwerk AG & Co. KGaA, Lübeck, Germany). Each endpoint will be analyzed individually. -Minute ventilation -Ventilation pressure -Leakage volume -Leakage minute volume -Leakage pressure	—
