Acute Cor Pulmonale, Acute Respiratory Distress Syndrome
Conditions
Brief summary
To compare the effect between mechanical ventilation strategy guided by transpulmonary pressure and tranditional lung protective ventilation strategy in acute respiratory distress syndrome for right ventricle protection.
Interventions
Mechanical ventilation parameters adjust guided by transpulmonary pressure monitoring. For pressure assist control or volumn assit control mode; inspiratory pressure or volumn setting needs to maintain Ppeak less than 25 cm H2O; PEEP was set at such a level that expiratory Ptp stayed between 0 and 5 cm H2O.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pulmonary vascular resistance (PVR) | 3 days | PVR will measured by Swan-Ganz catheter |
| Pulmonary vascular compliance | 3 days | Pulmonary vascular compliance will be calculated using pulmonary artery pressure divided by stroke output measured by Swan-Ganz catheter. |
