Table: Prospective, randomized trials with humidified nasal High Flow Oxygen (HFO) 1-8 Study Design Patients Treatment Primary Outcome Cuquemelle E et al. (2012) 1 intensive care unit N=30 HFO (N=18) versus standard HFO improved patient comfort by reducing follow up: 24hours parallel treatment, following 4hours pneumonia, acute chest syndrom, pulmonary oxygen (N=12) nasal dryness, but did not improve nasal airway caliber. cross-over embolism, Rittayamiai N et al. (2014) 2 intensive care unit N=17 HFO versus standard oxygen HFO reduced dyspnea and resulted in a follow up: 60min, crossover pneumonia, AECOPD, congestive heart failure, by non-rebreathing mask (each 30min, respectively) lower breathing frequency and heart rate compared to conventional oxygen therapy. Maggiore SM et al. (2014) 3 intensive care unit N=105 HFO (N=53) versus standard HFO resulted in a better oxygenation for the follow up: 48hours pneumonia, multiple trauma, atelectasis, shock, oxygen by venturi mask (N=52) same set FIO 2, and is associated with better comfort, fewer desaturations and interface displacements, and a lower reintubation rate Rittayamiai N et al. (2015) 4 emergency department N=40 HFO versus conventional HFO resulted in less dyspnea and better follow up: 60min congestive heart failure, asthmatic attack AECOPD, pneumonia, oxygen therapy comfort compared with conventional oxygen therapy Lemiale V et al. (2015) 5 intensive care unit N=100 HFO (N=52) versus standard HFO improved neither mechanical follow up: 2hours, crossover immunosuppression following solid and hematological malignancy, HIV oxygen by venturi mask (N=48). ventilatory assistance nor patient comfort compared with standard oxygen in this underpowered study. infection, steroid treatment, 2
