High-Flow Nasal Oxygen Cannula Compared to Non-Invasive Ventilation in Adult Patients With AcuTE Respiratory Failure

"HFNC will deliver through AIRVO2. FiO2 from 21 to 100% and heated humidified gas flow up to 60 l / min with temperature of the circuit maintained at 37 degrees.~Oxygen flow will be offered through a humidified nasal catheter. Flow and FiO2 will be titrated according to the protocol to maximize patient´s comfort and SpO2."

NIPPV will be performed using a facial mask (either oronasal or full face). NIPPV will deliver pressures and FiO2 tailored to specific ARF subgroups, according to the protocol. Adjustments of the inspiratory pressure (IPAP) and expiratory pressure (EPAP) and FiO2 according to protocol
