结局指标
主要结局
Regional ventilation monitored by EIT
时间窗: 5-10minutes
Using EIT to monitor the regional ventilation during supine and prone position, to monitor the ventilation distribution change.
Regional perfusion monitored by EIT
时间窗: 5-10minutes
Using EIT to monitor the regional perfusion during supine and prone position, to monitor the ventilation distribution change.
V/Q monitored by EIT
时间窗: 5-10minutes
Ventilation and perfusion monitored by EIT in supine and prone position. To evaluate the V/Q match, deadspace and shunt lung region.
次要结局
