We will compare various clinically relevant outcomes in patients treated for type II (hypercapnic) acute respiratory failure (ARF) with either High-Flow Nasal Cannula (HFNC) or Non-Invasive Ventilation (NIV) in a general adult hospital.~All patients treated with HFNC were treated with an Optiflow device (Fisher&Paykel). Various Bilevel positive airway pressure (BiPAP) devices were used during the study period.~All ventilatory parameters were set according to the treating physicians' preferences.
