Comparison of Actual Performance in the Flow and Fraction of Inspired O2 among Different High-Flow Nasal Cannula Devices: A Bench Study
Figure 2
The flow deviation at different set-flow levels in five devices (a). Flow deviation at different set-FiO2 levels when set at different set-flow levels in AIRVO 2 (b), TNI softFlow 50 (c), OH-70C (d), HUMID-BH (e), and bellavista 1000 (f). The flow deviation equals the actual-flow minus the corresponding set-flow.
