  • 2. Presence of the following criteria for moderate to severe ARDS as defined by the Berlin Criteria within 24 hours of the first infustion:
  • 1. Onset within 7 days of known clinical insult or requiring increasing respiratory rate, increasing oxygen flows, or increased work of breathing, and
  • 2. Bilateral lung opacities not fully explained by pleural effusions, atelectasis, or nodules, and
  • 3. PaO2/FiO2 (P/F ratio) ≤ 200 mm Hg, and
  • 4. Invasive or noninvasive ventilation with a minimum PEEP 5 cm H2O or minimum of continuous positive airway pressure (CPAP) 5 cm H2O, or High Flow Nasal Oxygen at ≥ 30 L/min, and
  • 5. Respiratory failure not fully explained by cardiac failure or fluid overload.

You may not qualify if…

  • 1. Lack of signed and dated informed consent form (either by the individual or by the individual's healthcare proxy).
