Summary

To investigate global and regional changes in lung ventilation and perfusion induced by prone position in ARDS patients assessed by 3D-EIT. And to investigate the difference between 2D-EIT and 3D-EIT in prone position monitoring.

Conditions

• ARDS (Acute Respiratory Distress Syndrome)
• Respiratory Failure

Interventions

Type	Name	Description
BEHAVIORAL	Prone position	Patients were ventilated based on the ARDS-Net recommendations . Patients were kept in a supine position. The process of lung ventilation and perfusion assessment was as follows: 1. PEEP was determined by the attending doctor and was kept the same during the supine and prone period. 2. 3D-EIT was used to monitor the ventilation and perfusion of ARDS patients at three timepoints: T1: supine position, T2: prone position at 30min, T3: prone position over 10 hours.
