Symmetrical high flow nasal cannula (HFNO)
"After a 'baseline' trial using Venturi Mask, within the first 120 minutes after extubation, and assessing a PaO2/FiO2 ratio \< 300, patients will be randomly assigned to a first 1h-phase of 'conventional HFNO' or 'DUET HFNO'. At the end of each session several clinical parameters (i.e. DUS, EIT, ABGs, comfort, VAS) will be collected.~Specifically, Gas-flow rate will be set at a maximum of 60 L/min, temperature at a maximum of 37°C, while FiO2 will be adjusted to maintain SpO2 between 92 and 98%."
