Quizplus · Accepted Answer

Venturi mask is the high-flow oxygen delivery system.
If a patient requires the oxygen to be delivered at FiO2 of 50 % to keep the safe oxygen saturation level, then the high-flow system is used. Venturi mask is the commonly used high-flow system. It provides 24% - 50% oxygen concentration.
Other options are low-flow oxygen delivery systems.
Nasal prongs are commonly used in low-flow oxygen delivery systems. Oxygen flow rate is from 1 liter to 6 liter/ min.
