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 F_iO₂ < 60% (mitigates oxygen toxicitty)
  • PEEP to prevent alveolar derecruitment (levels of 10-15 cm H₂O)
  • permissive hypercapnea
