Peak inspiratory flow

WebWhat does peak inspiratory flow mean? The PIFR is the maximal flow generated during a forced inspiratory maneuver. It is regularly measured without resistance during standard pulmonary function testing. When inhaling through a DPI, high internal resistance impacts the PIFR generated and needed for drug dispersion. WebFeb 8, 2024 · The analysis was used to recommend a strategy for setting the flow rate at or above the patient’s peak inspiratory flow when HFNT is used with a blender and equal to the patient’s peak inspiratory rate when bleed-in oxygen is used. The analysis also teaches how to titrate the settings to achieve a desired fraction of inhaled oxygen, (FiO2 ...
