Transpulmonary Pressure-guided Mechanical Ventilation Strategy in Right Ventricular Protection in Patients With ARDS

RecruitingNA

Sponsor: Beijing Chao Yang Hospital

Conditions: ARDS (Moderate or Severe)

Interventions: Transpulmonary pressure guided mechanical ventilation strategy

Countries: China

To verify whether the transpulmonary pressure-guided mechanical ventilation strategy can reduce right ventricular involvement, especially the incidence of acute cor pulmonale (ACP), in patients with moderate to severe ARDS induced by pneumonia compared with the currently widely used right ventricular protective mechanical ventilation strategy.
