Primary
| Measure | Time frame |
|---|---|
| derecruited lung volume from spontaneous breathing till mechanical ventilation after intubation, measured via electrical impedance tomography | — |
Secondary
| Measure | Time frame |
|---|---|
| derecruited lung volume between spontaneous breathing and mask ventilatio and between mask ventilation and intubated ventilation, Changes in dynamic respiratory system compliance, airway pressure and flow, tidal volumem easured at the ventilator, Measures of monitoring (heart rate, oxygen saturation endtidal CO2 partial pressure) | — |
