In a population of ARDS patients, we explore the influence of different PEEP levels on regional ventilation distribution, ventilation homogeneity, and the center of ventilation, optimal PEEP and lung recruitment potential as well as the extent of lung collapse and overdistension as detected by 3D-EIT.

| lung recruitment potential assessed by 3D EIT | Procedure | Patients were ventilated based on the ARDS-Net suggestions. The patients were kept at supine position. The lung recruitment potential assessed by 3D EIT was as follows:
|
| Measure | Description | Time Frame |
|---|---|---|
| OD/CL and optimal PEEP monitored by EIT | Monitoring the lung collapse and overdistension region by EIT at different PEEP levels. Measure the optimal PEEP level based on collapse and overdistension rate. | 5-10min |
| Measure | Description | Time Frame |
|---|---|---|
| ventilation distribution monitored by EIT | Monitoring the lung ventilation distribution by EIT at different PEEP levels | 5-10min |
| GI monitored by EIT | Global Inhomogeneity (GI) Index monitored by EIT at different PEEP levels |
