From: Inspiratory oscillatory flow with a portable ventilator: a bench study
Peak inspiratory flow. Correlation between the airway pressure amplitude (Paw-amplitude) and the ratio of the peak inspiratory flow with the Oxylog 3000™ to the peak inspiratory flow with the Evita-4 NeoFlow™ (flow-ratio ox/ev). Only measurements in the biphasic intermittent positive airway pressure or the intermittent positive pressure ventilation modes without leakage and without single spikes in the flow curve were included.
