    Disease stage Possible interventions Vasoplegia NO, almitrine, CO2 … FiO2, CPAP, NIV, Prone Hypoxemia position… Respiratory drive Opioids, sedatives…

  15. Slide 15: Progression of the disease: what can we do?

    Negative pressure Viral biology: Micro/macro thrombosis, Assess and control Anticoagulation ? Progression of the disease What can we do?

  16. Slide 16: Negative intrathoracic pressure

    Negative intrathoracic pressure • Esophageal pressure • How to assess • Surface electromyography • Clinical signs • CPAP? • How to control • NIV? • Mechanical ventilation

  17. Slide 17: Non invasive support: pro and con

    Non invasive support Pro Con • Increase PaCO2 • Increase oxygenation • May not decrease effort • May decrease the Ppl swings • Right ventricular failure • Acute Kidney Injury

  18. Slide 18: How I set the ventilator

    How I set the ventilator • Mode • FiO2 Remember that it is • Tidal Volume a long lasting disease • Respiratory rate • PEEP

  19. Slide 19: Which patient am I treating? Type L, Type H

    1. Which patient am I treating? Type L Type H

  20. Slide 20: Which patient am I treating? Type L, Type H

    1. Which patient am I treating? Type L Type H • Low elastance • High elastance • Low VA/Q • High shunt • Low lung weight • High lung weight • Low recruitability • High recruitability

  21. Slide 21: Mechanical ventilation Type L

    Mechanical ventilation Type L Sedation and muscle relax • Mode: Volume Controlled Ventilation Why? • FiO2: high as needed Why? • Tidal Volume: even > than 6 ml/kg Why? • Respiratory rate: try < 20 bpm Why? • PEEP: 8-10 cmH2O Why? • Prone position: only as a rescue Why?

  22. Slide 22: Mechanical ventilation Type L

    Mechanical ventilation Type L Sedation and muscle relax In these high compliance patients (> 50 ml/cmH2O) the plateau, driving pressure and mechanical power levels are well below the “classical” severe ARDS

  23. Slide 23: Mechanical ventilation Type H

    Mechanical ventilation Type H Sedation and muscle relax • Mode: Volume Controlled Ventilation Why? • FiO2: high as needed Why? • Tidal Volume: possibly 6 ml/kg Why? • Respiratory rate: to stay < 60 mmHg PaCO2 Why? • PEEP: possibly < 15 cmH2O Why? • Prone position: daily Why?

  24. Slide 24: Mechanical ventilation Type H

    Mechanical ventilation Type H Sedation and muscle relax In these low compliance patients (< 50 ml/cmH2O) the plateau, driving pressure and mechanical power levels are the same of the “classical” severe ARDS

  25. Slide 25: Weaning

    Weaning COVID-19 pneumonia lasts long, early weaning is problematic

  26. Slide 26: Remember

    Remember 1. More than 50% do not have a “classical” ARDS 2. It’s a long course disease 3. 10 cmH2O of PEEP, sedation and especially patience is likely the best we can offer
