Peking Union Medical College Hospital
30 participants
Oct 31, 2024
OBSERVATIONAL
Conditions
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.
Eligibility
Inclusion Criteria3
- patients on mechanical ventilation.
- Diagnosis of ARDS was based on the Berlin definition
- Patients in need of prone position because of clinical condition
Exclusion Criteria4
- Under 18 years of age.
- Pregnant women;
- Ribcage malformation
- Any contraindication to the use of EIT (e.g. automatic implantable cardioverter defibrillator, and implantable pumps).

Interventions
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.
