Design outcomes

Primary

Measure	Time frame
The temporal courses of pressure and flow rate are recorded as measured from the ventilator. After the experiments the intratidal profile of compliance is calculated from these data in an offline analysis.	—

Secondary

Measure	Time frame
Oxygenation is protocollized during the experiments. Data analysis is performed offline, after the experiments.	—
