Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Agreement between the estimated tidal volume (ml) using electrical impedance tomography and the tidal volume obtained using a flow sensor (ml), with mean bias under 50ml | — |
Secondary
| Measure | Time frame |
|---|---|
| Agreement between the estimate from tidal volume calibrated by pneumotachograph at spontaneous breathing (ml) and of the tidal volume estimated at different pressure levels (ml), with mean bias under 50ml;Agreement between the estimated tidal volume (ml) calibrated in sitting position and the same parameter obtained in supine position, with mean bias lower than 50ml;Comparison between tidal volume estimate (ml) based on electrical impedance tomography signals and an algorithm that estimates tidal volume (ml) adding anthropometric information | — |
