Abstract

High-flow nasal cannula (HFNC) is a non-invasive respiratory support increasingly applied to hypoxemic acute respiratory failure patients. HFNC decreases dyspnea, improves oxygenation and enhances patient's comfort.

Highlights

  • High-flow nasal cannula (HFNC) is a non-invasive respiratory support increasingly applied to hypoxemic acute respiratory failure patients

  • In the present study, to identify the mechanisms underlying the clinical benefits associated with HFNC, we measured in hypoxemic non-intubated critically ill patients the effects of HFNC on lung aeration, patient’s effort and CO2 washout efficiency

  • 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
