Ventilator Therapy for ED Patients with ARDS

  • As we manage critically ill patients for longer periods of time, it is likely that many of us will manage patients who develop ARDS
  • Current mortality for patients with ARDS ranges from 30-40%
  • ED treatment for patients with ARDS includes treating the inciting event, supportive critical care, and ventilator management
  • Current ventilator management in patients with ARDS includes:
    • avoiding alveolar overdistention (tidal volumes of 6 ml/kg)
    • maintaining FiO2 < 60% (mitigates oxygen toxicitty)
    • PEEP to prevent alveolar derecruitment (levels of 10-15 cm H2O)
    • permissive hypercapnea
