Study Arms (1)
Adjustment of ventilator settings by EIT
EXPERIMENTALIndividual Adjustment of Ventilator settings using an algorithm based on electrical impedance tomography.
Interventions
Diagnostic maneuvers (change in tidal volume, recruitment maneuvers) will be performed to detect overdistention, tidal recruitment and recruitability. Tidal volume will be reduced if overdistention is detected by EIT. Positive end-expiratory pressure will be increased if tidal recruitment or recruitability are detected.
Eligibility Criteria
You may qualify if:
- Acute Respiratory Distress Syndrome (according to Berlin Definition)
You may not qualify if:
- Hemodynamic Instability (defined as mean arterial pressure \< 65 mmHg OR heart rate \< 40 / min OR heart rate \> 150 / min OR cardiac index \< 2.0 l/min/m\^2 DESPITE adequate fluid resuscitation and adequate therapy with inotropes and / or vasopressors)
- Thoracic burns or severe skin injuries
- High frequency oscillatory ventilation
- Pregnancy
- Severe chronic obstructive pulmonary disease (GOLD IV)
- Esophageal varices \> grade I
- Esophageal resection
- Inspiratory oxygen requirement \> 80%
