Methods We performed a prospective randomized cross-over study on hypoxemic (PaO2/FiO2 ≤300 mmHg) non-intubated patients admitted to Intensive Care Unit of San Gerardo Hospital. We delivered the same air/oxygen mix by HFNC (40 L/min) and facial mask for 20 minutes by random order. Continuous recordings of lung aeration and minute ventilation by Electrical Impedance Tomography (EIT) and of inspiratory effort by esophageal pressure swings (ΔPes) were obtained.
