Figure 4
The FiO2 deviation at different set-FiO2 levels in five devices (a). The FiO2 deviation at different set-flow levels when set at different set-FiO2 levels in AIRVO 2 (b), TNI softFlow 50 (c), OH-70C (d), HUMID-BH (e), and bellavista 1000 (f). The FiO2 deviation equals the actual-FiO2 minus the corresponding set-FiO2.
